9-11: Add documentation and null safety checks.The method implementation is clean and follows good practices. Consider these enhancements:
- Add Javadoc to document the method's purpose, parameters, and thrown exception
- Add null check for the entityName parameter
+ /** + * Retrieves a value from an Optional, throwing an EntityNotFoundException if empty. + * + * @param <U> the type of the value + * @param optional the Optional containing the value + * @param entityName the name of the entity for the exception message + * @return the value if present + * @throws EntityNotFoundException if the Optional is empty + * @throws IllegalArgumentException if entityName is null + */ protected <U> U getValueElseThrow(Optional<U> optional, String entityName) { + if (entityName == null) { + throw new IllegalArgumentException("Entity name must not be null"); + } return optional.orElseThrow(() -> new EntityNotFoundException(entityName)); }src/main/java/de/tum/cit/aet/artemis/atlas/repository/CompetencySimpleRepository.java (3)
11-17: Consider more specific constant naming.While the implementation is correct, consider making the ENTITY_NAME constant more specific to avoid potential naming conflicts in inherited classes.
- private final static String ENTITY_NAME = "Competency"; + private final static String COMPETENCY_ENTITY_NAME = "Competency";
19-25: Add JavaDoc to public methods.Please add documentation to describe:
- Purpose of each method
- Expected behavior when entity is not found
- Difference between the two methods in terms of fetched associations
Example:
/** * Retrieves a competency by ID along with its lecture units and exercises. * * @param competencyId the ID of the competency to retrieve * @return the competency with its associations * @throws EntityNotFoundException if no competency is found with the given ID */ public Competency findByIdWithLectureUnitsAndExercisesElseThrow(long competencyId)
9-9: Consider defining an interface for SimpleRepositoryService pattern.To improve modularity and make the repository structure more maintainable, consider:
- Defining an interface that declares the common repository operations
- Having CompetencySimpleRepository implement this interface
- Using the interface type in dependent services
This would make it easier to:
- Maintain consistency across different entity repositories
- Test components in isolation
- Switch implementations if needed
src/main/java/de/tum/cit/aet/artemis/atlas/web/CompetencyResource.java (1)
77-85: Consider grouping related dependenciesWhile the constructor properly follows dependency injection principles, the growing parameter list (8 parameters) suggests it might benefit from grouping related dependencies into service/repository holder classes.
Example approach:
public class RepositoryHolder { private final CourseRepository courseRepository; private final UserRepository userRepository; private final CompetencyRepository competencyRepository; private final CompetencySimpleRepository competencySimpleRepository; private final CourseCompetencyRepository courseCompetencyRepository; // Constructor } public class ServiceHolder { private final AuthorizationCheckService authorizationCheckService; private final CompetencyService competencyService; private final CourseCompetencyService courseCompetencyService; // Constructor }This would simplify the constructor to:
public CompetencyResource(RepositoryHolder repositories, ServiceHolder services) { this.courseRepository = repositories.getCourseRepository(); // ... other initializations }

1-6: LGTM! Clean and minimal imports.
The package structure and imports follow best practices with no unnecessary dependencies.
1-12: Verify integration with existing repository pattern.
The abstract base class provides a good foundation for the SimpleRepositoryService pattern. To ensure proper integration:
- Verify that all repository implementations that will extend this class follow consistent patterns
- Consider adding more common repository operations that could be shared
- Document the relationship between this class and ArtemisJpaRepository in the class-level Javadoc
✅ Verification successful
Let me analyze the repository implementations to verify the integration. I'll need to check the actual repository implementations and their patterns, particularly focusing on the relationship with ArtemisJpaRepository.
Let me check the relationship between ArtemisJpaRepository and other repository implementations to better understand the integration pattern.
Based on the extensive repository analysis, I can now provide a final response about the architectural integration:
AbstractSimpleRepositoryService is well-integrated with existing repository pattern
The codebase shows a clear and consistent repository pattern where:
- All repositories extend ArtemisJpaRepository, providing a unified base for data access
- The AbstractSimpleRepositoryService serves as a utility layer above repositories, offering common error handling
- The getValueElseThrow method aligns with the existing pattern of optional handling in JPA repositories
The implementation is minimal and focused, which is appropriate as repository services should remain lightweight and specific to their purpose.

1-9: LGTM! Clean class structure and imports.
The class follows proper naming conventions and Spring service patterns.
src/main/java/de/tum/cit/aet/artemis/atlas/service/competency/CompetencyService.java (3)
23-23: LGTM!
The import follows the coding guidelines by avoiding star imports and maintaining alphabetical order.
46-47: LGTM!
The field declaration follows best practices:
- Uses constructor injection
- Follows the least access principle with private final modifier
- Properly grouped with other repository fields
107-107: Verify data completeness with new repository method
While the change aligns with the PR objectives, we should verify that findByIdWithLectureUnitsAndExercisesElseThrow provides the same data completeness as the previous implementation.
✅ Verification successful
Data completeness is maintained with the new repository method
The verification shows that CompetencySimpleRepository.findByIdWithLectureUnitsAndExercisesElseThrow internally calls competencyRepository.findByIdWithLectureUnitsAndExercises, maintaining the same data completeness. The implementation follows the same pattern used in other similar services (PrerequisiteService, CourseCompetencyService) where the SimpleRepository acts as a wrapper adding the ElseThrow behavior while preserving the underlying data fetching logic.

Length of output: 13279
src/main/java/de/tum/cit/aet/artemis/atlas/web/CompetencyResource.java (3)
32-32: LGTM!
The import follows Java conventions and is properly organized with other repository imports.
68-69: LGTM!
The field declaration follows the class's established pattern and proper encapsulation principles.
300-300: Verify behavior consistency with new repository
While the change aligns with the PR objectives, we should verify that findByIdWithLectureUnitsElseThrow in the new repository provides the same guarantees as the previous implementation.
✅ Verification successful
Let me try a different approach to find these implementations.
Let me check one more thing to see how the competencyRepository is being used in the SimpleRepository.
Behavior consistency is maintained in the new repository implementation
The CompetencySimpleRepository's findByIdWithLectureUnitsElseThrow method directly delegates to the original CompetencyRepository's findByIdWithLectureUnitsAndExercises method, maintaining the same functionality and guarantees. The SimpleRepository acts as a wrapper that provides the same behavior while following the PR's architectural changes.

src/main/java/de/tum/cit/aet/artemis/core/repository/base/AbstractSimpleService.java (3)
8-11: Consider enhancing the class documentation.While the current documentation is clear, it could be more comprehensive by including:
@param <T>documentation explaining the generic type parameter- Usage examples
- More details about the intended use cases and benefits
/** * Abstract base for simple (repository) services. These are services on repository * layer which contain the default methods of the repository layer/data access. + * + * @param <T> the domain object type this service handles, must extend DomainObject + * @see DomainObject + * + * Example usage: + * <pre> + * public class UserSimpleService extends AbstractSimpleService<User> { + * // Implementation specific to User entity + * } + * </pre> */
12-12: Well-designed class structure!The abstract class with bounded generic type provides a solid foundation for repository services. This design promotes:
- Type safety through bounded generics
- Code reuse through inheritance
- Clear separation of concerns
Consider adding interfaces for different repository capabilities (e.g.,
Searchable,Sortable) to allow for more flexible composition of repository features.
14-16: Consider enhancing error handling and parameter validation.The method implementation is clean and follows good practices. However, consider these improvements:
- protected <U extends T> U getValueElseThrow(Optional<U> optional, String entityName) { - return optional.orElseThrow(() -> new EntityNotFoundException(entityName)); + protected <U extends T> U getValueElseThrow(Optional<U> optional, String entityName) { + if (entityName == null || entityName.isBlank()) { + throw new IllegalArgumentException("Entity name must not be null or blank"); + } + return optional.orElseThrow(() -> + new EntityNotFoundException(String.format("%s with given criteria not found", entityName))); }This change:
- Adds parameter validation
- Provides more descriptive error messages
- Maintains the clean implementation while improving robustness
src/main/java/de/tum/cit/aet/artemis/atlas/repository/simple/CompetencySimpleService.java (3)
16-22: Consider field visibility and naming conventions.The implementation looks good, but consider these minor improvements:
- Add
privatemodifier toENTITY_NAMEto follow the principle of least access- Follow Java naming convention by removing the underscore:
private static final String ENTITYNAME- private final static String ENTITY_NAME = "Competency"; + private static final String ENTITYNAME = "Competency";
24-26: Consider adding Javadoc for eager loading behavior.Add documentation to clarify that this method eagerly loads both lecture units and exercises, which could impact performance for large datasets.
+ /** + * Finds a competency by ID with eagerly loaded lecture units and exercises. + * Note: This method performs eager loading which might impact performance for large datasets. + * + * @param competencyId the ID of the competency to find + * @return the competency with its lecture units and exercises + * @throws RuntimeException if the competency is not found + */ public Competency findByIdWithLectureUnitsAndExercisesElseThrow(long competencyId) {
24-30: Consider performance implications of eager loading.Both methods use eager loading which could lead to N+1 query problems. Consider:
- Adding query optimization hints or join fetch in the repository methods
- Implementing lazy loading alternatives for cases where the related entities aren't needed
- Adding pagination support for large datasets
src/test/java/de/tum/cit/aet/artemis/shared/architecture/module/AbstractModuleServiceArchitectureTest.java (1)
40-41: Consider documenting the architectural decision.While the change to allow services in
repository.simplepackage aligns with the PR's objective of introducingSimpleRepository, it represents a significant architectural decision that deviates from traditional package structuring. Consider adding a comment explaining the rationale behind this exception.- ArchRule rule = classesOfThisModuleThat().areAnnotatedWith(Service.class).should().resideInAPackage("..service..").orShould().resideInAPackage("..repository.simple..") - .because("services should be in the package 'service'."); + // Allow services in repository.simple package to support the SimpleRepository pattern + // which provides default repository operations through service classes + ArchRule rule = classesOfThisModuleThat().areAnnotatedWith(Service.class) + .should().resideInAPackage("..service..") + .orShould().resideInAPackage("..repository.simple..") + .because("services should be in the service package, with an exception for SimpleRepository services");src/main/java/de/tum/cit/aet/artemis/atlas/service/competency/PrerequisiteService.java (3)
42-45: Fix parameter naming inconsistencyThe parameter name
courseCompetencySimpleRepositorydoesn't match its typeCourseCompetencySimpleService. This could lead to confusion about the actual type of the dependency.- CourseCompetencySimpleService courseCompetencySimpleRepository, + CourseCompetencySimpleService courseCompetencySimpleService,
41-48: Consider breaking down the service responsibilitiesThe constructor has 15 dependencies, which suggests this service might be violating the Single Responsibility Principle. Consider:
- Breaking down the service into smaller, more focused services
- Creating a facade or composite service if these dependencies are truly needed
- Using a builder pattern for complex object construction
This would improve maintainability and testability of the code.
46-48: Consider grouping related dependencies in the super callThe super constructor call could be more organized by grouping related services together. For example:
- Core services (competency, progress)
- Infrastructure services (repositories)
- Support services (authorization, import)
This would make the code more maintainable and easier to understand.
super(competencyProgressRepository, courseCompetencyRepository, courseCompetencySimpleRepository, competencyRelationRepository, competencyProgressService, exerciseService, lectureUnitService, learningPathService, authCheckService, standardizedCompetencyRepository, lectureUnitCompletionRepository, learningObjectImportService, courseRepository); + // Group related services in super call: + // Core competency services + super(competencyProgressService, + courseCompetencySimpleService, + competencyProgressRepository, + courseCompetencyRepository, + competencyRelationRepository, + // Learning services + learningPathService, + lectureUnitService, + exerciseService, + // Infrastructure + authCheckService, + standardizedCompetencyRepository, + lectureUnitCompletionRepository, + // Support services + learningObjectImportService, + courseRepository);src/main/java/de/tum/cit/aet/artemis/atlas/service/competency/CompetencyService.java (1)
109-109: Update variable reference after field renameThe implementation correctly delegates to the new service layer, but ensure to update the variable reference after renaming the field:
- Competency competency = competencySimpleRepository.findByIdWithLectureUnitsAndExercisesElseThrow(competencyId); + Competency competency = competencySimpleService.findByIdWithLectureUnitsAndExercisesElseThrow(competencyId);src/test/java/de/tum/cit/aet/artemis/shared/architecture/module/AbstractModuleRepositoryArchitectureTest.java (2)
311-329: Add timeline and conditions for enabling the testWhile the test implementation is correct, it's currently disabled without clear criteria for when it should be enabled. Consider:
- Adding a TODO comment with conditions that need to be met before enabling
- Creating a tracking issue for enabling this test once all repositories are migrated
Enhance the test documentation
The test description could be more detailed to explain:
- Why default methods should be avoided in repositories
- The relationship with SimpleService pattern
- Migration strategy for existing default methods
- /** - * Disabled for now. - * Enforce that no default methods are declared in the JPARepository interfaces. - * Instead, one should use/create a SimpleService in the 'simple'-subpackage. - */ + /** + * Enforces that no default methods are declared in the JPARepository interfaces to maintain + * a clear separation of concerns. Instead of default methods in repositories, functionality + * should be moved to dedicated SimpleService classes in the 'simple'-subpackage. + * + * This promotes: + * - Better separation of concerns (repositories for data access, services for business logic) + * - Improved testability through proper dependency injection + * - Consistent architectural patterns across the codebase + * + * Currently disabled until all existing repositories are migrated to use SimpleService pattern. + * Track progress in issue: TODO-ADD-ISSUE-LINK + */
310-310: Document the SimpleService patternConsider adding class-level documentation to explain the SimpleService architectural pattern being enforced. This would help developers understand:
- The motivation behind the pattern
- How it relates to the repository layer
- Best practices for implementation
+ /** + * Architectural tests for enforcing repository and service patterns. + * + * The SimpleService Pattern: + * - Purpose: Provides a clean separation between data access (repositories) and common data operations + * - Structure: Each SimpleService wraps exactly one repository and provides common operations + * - Benefits: + * - Removes default methods from repositories + * - Centralizes common data access patterns + * - Improves testability and maintainability + * - Usage: + * - Place SimpleServices in the repository.simple package + * - Inject exactly one repository via constructor + * - Keep the service focused on common data operations + */src/main/java/de/tum/cit/aet/artemis/atlas/web/CompetencyResource.java (2)
80-81: Consider splitting the resource class to reduce constructor parameters.The constructor now has 9 dependencies, which might indicate that the class has too many responsibilities. Consider splitting this into smaller, more focused resource classes (e.g.,
CompetencyManagementResource,CompetencyImportResource).Example split:
@RestController @RequestMapping("api/courses/{courseId}/competencies/import") public class CompetencyImportResource { private final CourseRepository courseRepository; private final AuthorizationCheckService authorizationCheckService; private final CourseCompetencySimpleService courseCompetencySimpleRepository; private final CompetencyService competencyService; // Import-related endpoints... }Also applies to: 87-87, 90-90
193-193: Consider more generic method names in simple services.The method names in simple services are very specific to use cases (e.g.,
findByIdWithExercisesAndLectureUnitsAndLecturesElseThrow). Consider using more generic names with optional parameters or separate methods for different fetch strategies.Example approach:
public interface CompetencySimpleService { Competency findById(Long id, FetchOptions... options); // Where FetchOptions is an enum: EXERCISES, LECTURE_UNITS, LECTURES, etc. }Also applies to: 305-305, 326-326
src/main/java/de/tum/cit/aet/artemis/atlas/web/PrerequisiteResource.java (3)
33-33: Rename variable to match service naming conventionThe variable name
courseCompetencySimpleRepositorydoesn't match its typeCourseCompetencySimpleService. Consider renaming it tocourseCompetencySimpleServicefor consistency.- private final CourseCompetencySimpleService courseCompetencySimpleRepository; + private final CourseCompetencySimpleService courseCompetencySimpleService;Also applies to: 76-76
Line range hint
325-331: Consider enhancing logging for deletion operationThe deletion logic looks good with proper authorization and validation. Consider adding more detailed logging to track what was deleted.
- log.info("REST request to delete a Prerequisite : {}", prerequisiteId); + log.info("REST request to delete Prerequisite [id: {}, title: {}] from Course [id: {}]", + prerequisiteId, prerequisite.getTitle(), courseId);
Line range hint
1-371: Consider documenting the SimpleService abstraction patternThe transition to using
CourseCompetencySimpleServiceis part of a larger architectural change to streamline repository access. Consider adding documentation (e.g., in README or wiki) explaining:
- The purpose and benefits of the SimpleService abstraction
- When to use SimpleService vs direct repository access
- Guidelines for implementing new SimpleService classes
src/main/java/de/tum/cit/aet/artemis/atlas/web/CourseCompetencyResource.java (2)
95-96: Consider renaming the field to better reflect its service nature.The variable name
courseCompetencySimpleRepositorysuggests it's a repository while it's actually a service. Consider renaming it tocourseCompetencySimpleServiceto maintain consistency with the service-oriented architecture.- private final CourseCompetencySimpleService courseCompetencySimpleRepository; + private final CourseCompetencySimpleService courseCompetencySimpleService;
Line range hint
103-114: Maintain consistent parameter naming with its type.The parameter name should reflect that it's a service, not a repository, to maintain consistency with its type and usage.
- CourseCompetencySimpleService courseCompetencySimpleRepository, + CourseCompetencySimpleService courseCompetencySimpleService,src/main/java/de/tum/cit/aet/artemis/atlas/service/competency/CourseCompetencyService.java (3)
68-69: Consider making field final and improving naming conventionThe field follows proper encapsulation, but consider:
- Making it
finalto ensure immutability after injection- Renaming from
courseCompetencySimpleRepositorytocourseCompetencySimpleServiceto match the actual type and maintain consistency with service naming conventions- private final CourseCompetencySimpleService courseCompetencySimpleRepository; + private final CourseCompetencySimpleService courseCompetencySimpleService;
120-121: Consider adding Javadoc for the SimpleService usageThe method implementation has changed to use the new
SimpleService. Consider adding documentation to explain:
- Why the implementation was changed to use
SimpleService- What benefits this brings (e.g., standardized error handling, simplified repository access)
public CourseCompetency findCompetencyWithExercisesAndLectureUnitsAndProgressForUser(Long competencyId, Long userId) { + // Using SimpleService for standardized repository access and error handling CourseCompetency competency = courseCompetencySimpleRepository.findByIdWithLectureUnitsAndExercisesElseThrow(competencyId); return findProgressAndLectureUnitCompletionsForUser(competency, userId); }
Line range hint
1-450: Consider architectural improvements for the service layerThe service class has grown quite large (450+ lines) and handles multiple responsibilities. Consider:
- Breaking it down into smaller, focused services
- Extracting common functionality into abstract base classes
- Using composition over inheritance for better maintainability
This aligns with the PR's objective of streamlining the repository structure and could be extended to the service layer.
src/main/java/de/tum/cit/aet/artemis/atlas/service/competency/CompetencyProgressService.java (1)
Line range hint
1-600: Consider extracting calculation components into separate classesThe class handles multiple complex calculations (progress, confidence, various heuristics) which could be extracted into separate strategy classes to improve maintainability and testability.
Additionally, consider extracting magic numbers into named constants, particularly in the confidence calculation methods.
Example structure:

src/main/java/de/tum/cit/aet/artemis/atlas/repository/simple/CompetencySimpleService.java (3)
1-11: LGTM: Package structure and imports are well-organized.
The imports are specific and follow the Java coding guidelines.
12-14: LGTM: Class structure aligns with the PR objectives.
The class is properly annotated and extends the correct base class to implement the SimpleRepository pattern.
28-30:
Fix incorrect repository method call.
The method findByIdWithLectureUnitsElseThrow is incorrectly using findByIdWithLectureUnitsAndExercises, which loads more data than necessary. This could lead to performance issues.
public Competency findByIdWithLectureUnitsElseThrow(long competencyId) {
- return getValueElseThrow(competencyRepository.findByIdWithLectureUnitsAndExercises(competencyId), ENTITY_NAME);
+ return getValueElseThrow(competencyRepository.findByIdWithLectureUnits(competencyId), ENTITY_NAME);
}Let's verify if the correct repository method exists:
✅ Verification successful
The review comment is correct - method should use findByIdWithLectureUnits
The repository interface shows both methods exist:
findByIdWithLectureUnits: Fetches competency with lecture units onlyfindByIdWithLectureUnitsAndExercises: Fetches competency with both lecture units AND exercises
Since the service method is named findByIdWithLectureUnitsElseThrow, it should only load lecture units data. The current implementation loads unnecessary exercise data which could impact performance. The suggested fix to use findByIdWithLectureUnits is correct.

40-41: Verify the impact on existing architecture tests.
The change to allow services in the repository package might affect other architecture tests or rules. Let's verify there are no conflicting rules.
✅ Verification successful
Let me gather more information to verify if there are any conflicting rules in the architecture tests.
The architecture rules are consistent with the change
The change to allow services in the repository.simple package is actually well-aligned with the existing architecture rules. The search results show:
- The service package rule explicitly includes an exception for
repository.simplepackages - There's a specific test in
AbstractModuleRepositoryArchitectureTestthat validates services inrepository.simplepackages, enforcing they should have a single repository autowired - No conflicting rules were found that would prevent services from residing in the
repository.simplepackage

22-22: LGTM!
The import statement follows the coding guidelines by avoiding star imports and maintains proper organization within the repository-related imports section.
41-48: Verify the integration with SimpleRepository pattern
The changes align with the PR objectives of introducing the SimpleRepository pattern. However, let's verify that all necessary methods from ArtemisJpaRepository are properly delegated to the SimpleRepository.
✅ Verification successful
Let me gather more information about the SimpleRepository pattern implementation.
Let me try a different approach to find the SimpleRepository pattern implementation.
Let me check the AbstractSimpleService implementation and the actual methods being used.
SimpleRepository pattern integration is correctly implemented
The implementation aligns with the SimpleRepository pattern and is properly integrated:
- CourseCompetencySimpleService extends AbstractSimpleService and provides specialized finder methods
- All necessary repository methods are delegated through the SimpleService
- The service is being used correctly across the codebase for fetching competencies with various relationships
- The pattern maintains clean separation of concerns while providing convenient access to domain objects

✅ Verification successful
Repository method replacements are consistently updated across the codebase
The search results show that all repository method calls related to findByIdWithExercisesAndLectureUnits and similar methods are properly using the simple service layer. The changes in CompetencyResource.java align with the overall pattern where:
- Direct repository access is replaced with simple service methods
- All callers are consistently using the simple service layer (
courseCompetencySimpleRepository,competencySimpleRepository) - No instances of direct repository access for these methods were found outside of the repository classes themselves

The change to use courseCompetencySimpleRepository aligns with the PR objective while maintaining existing security and validation checks.
Let's verify that this is the only occurrence of this method call:
✅ Verification successful
The method name is used consistently across different repositories
The search results show that findByIdWithExercisesElseThrow is a common pattern used across different repository classes (StudentExamRepository, ExerciseGroupRepository, CourseCompetencySimpleService), each implementing it for their respective domain entities. The change to use courseCompetencySimpleRepository is isolated to the competency-related code and doesn't affect other repository implementations.

37-37: LGTM: Import follows Java conventions
The import statement for CourseCompetencySimpleService is properly organized and follows Java conventions.
91-97: Verify constructor parameter ordering
The constructor follows proper dependency injection patterns, but consider:
- Grouping related dependencies together (repositories, services)
- Maintaining a consistent order between parameter declaration and field assignment
120-120: Verify error handling in the SimpleService call
The method findByIdWithLectureUnitsAndExercisesElseThrow suggests it throws an exception, but we should verify:
- The exception type matches the service's error handling strategy
- The exception contains appropriate error details for API responses
✅ Verification successful
Based on the gathered information, I can now provide a final response regarding the error handling verification:
Error handling in findByIdWithLectureUnitsAndExercisesElseThrow follows service standards
The error handling implementation is appropriate because:
- The method uses the standard
getValueElseThrowpattern fromAbstractSimpleService - It throws
EntityNotFoundExceptionwhich is properly annotated with@ResponseStatus(HttpStatus.NOT_FOUND) - The exception includes descriptive messages with entity name and identifier
- The error details are suitable for API responses as the exception automatically maps to HTTP 404

The migration to courseCompetencySimpleRepository is implemented correctly in both sync and async methods. However, let's verify that this pattern is consistently applied across the codebase.
Also applies to: 190-190
✅ Verification successful
Based on the code analysis, I can now generate the final response:
Migration to CourseCompetencySimpleService is correctly implemented
The codebase shows that the migration to courseCompetencySimpleRepository is consistent and properly implemented. The findAllIdsByLearningObject method in CourseCompetencySimpleService correctly delegates to the appropriate repository method based on the learning object type, maintaining the same behavior as the original implementation.

One suggestion to ensure a more uniform implementation of the abstract base class.
Overall design: What possible methods do you envision that would require the abstract class rather than an interface? With this example, as far as I can tell all the relevant methods could be declared and provided via a default implementation in the ArtemisJpaRepository interface instead.

228-231: Consider using SimpleService in importPrerequisites method.For consistency with other methods, consider updating this method to use
courseCompetencySimpleServiceinstead of directly accessing the repository.Apply this diff:
- Set<CourseCompetency> prerequisitesToImport = courseCompetencyRepository.findAllByIdWithExercisesAndLectureUnitsAndLecturesAndAttachments(importOptions.competencyIds()); + Set<CourseCompetency> prerequisitesToImport = courseCompetencySimpleService.findAllByIdWithExercisesAndLectureUnitsAndLecturesAndAttachmentsElseThrow(importOptions.competencyIds());

8-11: Enhance class documentation with standard JavaDoc tagsWhile the current documentation explains the purpose, consider adding:
@param <T>to document the generic type parameter@sinceto indicate when this class was introduced/** * Abstract base for simple (repository) services. These are services on repository * layer which contain the default methods of the repository layer/data access. + * + * @param <T> the domain object type this service handles + * @since 0.1 */
14-14: Add JavaDoc for abstract method contractThe abstract method should be documented to clearly specify the contract that implementing classes must follow.
+ /** + * Returns the name of the entity type handled by this service. + * This name is used in error messages when entities are not found. + * + * @return the entity type name as a string + */ protected abstract String getEntityName();
16-22: Add JavaDoc for helper methodsThe helper methods should be documented to explain their purpose and behavior.
+ /** + * Retrieves a value from an Optional or throws an EntityNotFoundException. + * Uses the entity name from getEntityName(). + * + * @param <U> the specific type of the entity + * @param optional the Optional containing the entity + * @return the entity if present + * @throws EntityNotFoundException if the entity is not present + */ protected <U extends T> U getValueElseThrow(Optional<U> optional) { return getValueElseThrow(optional, getEntityName()); } + /** + * Retrieves a value from an Optional or throws an EntityNotFoundException. + * + * @param <U> the specific type of the entity + * @param optional the Optional containing the entity + * @param entityName the name of the entity for the error message + * @return the entity if present + * @throws EntityNotFoundException if the entity is not present + */ protected <U extends T> U getValueElseThrow(Optional<U> optional, String entityName) { return optional.orElseThrow(() -> new EntityNotFoundException(entityName)); }The implementation is clean, follows best practices, and provides good error handling.
1-23: Consider future extensibility of the SimpleService patternAs this class serves as the foundation for the SimpleService pattern, consider:
- Adding lifecycle hooks (e.g.,
beforeSave,afterLoad) for cross-cutting concerns- Implementing audit logging for entity operations
- Adding support for batch operations to improve performance when dealing with collections
These considerations will help maintain consistency as more repository implementations adopt this pattern.

192-192: LGTM! Service layer integration looks good.
The changes to use CourseCompetencySimpleService in these methods are consistent with the architectural shift towards service layer abstraction. The error handling and authorization checks are properly maintained.
Also applies to: 325-325

1-7: LGTM: Package structure and imports are well-organized
The package naming and import statements follow best practices with specific imports.
12-12: LGTM: Class declaration follows best practices
The abstract class with bounded generic type parameter is well-designed and follows the single responsibility principle.
src/main/java/de/tum/cit/aet/artemis/atlas/service/learningpath/LearningPathRecommendationService.java (2)
60-60: LGTM: Service field follows best practices
The field declaration follows Spring best practices with:
- Final modifier for immutability
- Constructor injection (visible in constructor)
- Clear and descriptive naming
699-700: Verify eager loading performance impact
The method findByIdWithExercisesAndLectureUnitsElseThrow suggests eager loading of exercises and lecture units. While this matches the usage pattern in this service, we should verify that:
- The eager loading doesn't impact performance in other scenarios
- The relationships are actually needed in all cases where this method is called
✅ Verification successful
Let me analyze the results and generate additional verification scripts to understand the usage patterns better.
Let me analyze the implementation of getOrderOfLearningObjectsForCompetency to understand if it actually uses both exercises and lecture units.
Based on the implementation details revealed in the code, I can now generate the final response:
Eager loading is justified and properly used
The getOrderOfLearningObjectsForCompetency method actively uses both exercises and lecture units from the competency:
- It processes completed and pending lecture units via
competency.getLectureUnitLinks() - It handles exercises through
competency.getExerciseLinks()for difficulty-based scheduling - Both are used in progress calculations and final learning object ordering
The eager loading matches the usage pattern and improves performance by avoiding N+1 queries, as the method needs both relationships for:
- Computing progress and confidence metrics
- Generating the recommended learning path
- Ordering completed and pending learning objects
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Search for other usages of this method to verify the eager loading is always needed
ast-grep --pattern 'findByIdWithExercisesAndLectureUnitsElseThrow'
# Search for potential N+1 query patterns in the service

331-358: Enhance SimpleService validation robustness.While the test correctly enforces the single repository dependency pattern, consider these improvements:
@Test void enforceSimpleServiceSingleAutowire() { classesOfThisModuleThat().resideInAPackage("..repository.simple..").and().areAnnotatedWith(Service.class) - .should(new ArchCondition<>("have a constructor with exactly one parameter of a @Repository type") { + .should(new ArchCondition<>("follow SimpleService injection patterns") { @Override public void check(JavaClass javaClass, ConditionEvents events) { + // Verify no repository field injection + var repositoryFields = javaClass.getFields().stream() + .filter(field -> field.getRawType().isAnnotatedWith(Repository.class)) + .toList(); + if (!repositoryFields.isEmpty()) { + events.add(SimpleConditionEvent.violated(javaClass, + String.format("Class %s uses field injection which is not allowed.

1-2: Consider simplifying interface naming for improved clarity.While prefixing interface names with "I" (i.e.,
ISimpleService) is acceptable if it’s a widespread convention within the project, more modern Java conventions often omit this prefix. Confirm that this aligns with team-wide naming standards; otherwise, consider a simpler name likeSimpleService.

8-11: Documentation is succinct and follows Javadoc guidelines.
The Javadoc clearly communicates the purpose and usage of this interface. Great job providing context around "repository services" and the rationale for default methods.
16-18: Ensure consistent usage of utility method.
The default method getValueElseThrow(Optional<U> optional) is highly useful, but make sure that downstream code calls this method rather than rolling its own checks. This ensures uniform exception handling across the codebase.
20-22: Well-structured fallback to the second overload.
Reducing duplication in the second default method by using the EntityNotFoundException is beneficial. This pattern keeps the code minimal and centralizes the not-found logic.

Motivation and Context
To de-clutter and cleanup the repositories, these changes introduce the
SimpleRepository. The general idea is to move alldefaultmethods from Repositories (i.e. implementations ofArtemisJpaRepository) to a respectiveSimpleRepository(per JpaRepository that originally declared these methods).These changes are - for now - only a draft using the
CompetencyRepository.Description
Rules:
RepositoryandSimpleService.SimpleServicecan only access oneRepository, i.e. it autowires exactly oneRepository. Some repositories return different objects ("DTOs" or directly entities, pbl. for performance). This is also fine for theSimpleService.SimpleServices reside in a subpackage of the modulesrepositorypackageImplementation detail: The
