jpa/boot-read-replica-postgresql/src/test/java/com/example/demo/readreplica/controller/ArticleControllerIntTest.java (1)
32-55: Relying on a hard-coded ID and data might lead to fragile tests.The test expects an article with ID
1and a specific title in the data store. If this fixture data is missing or changed, the test would fail. Consider dynamically creating this fixture or using an in-memory DB seeder so the test remains resilient and self-contained.jpa/boot-read-replica-postgresql/src/main/java/com/example/demo/readreplica/domain/CommentDTO.java (1)
7-9: Consider null checks or validations.While this conversion is straightforward, it may be beneficial to handle potential cases where
commentDTOis null or where itscomment()value is invalid. Adding basic null checks or assertions can increase safety.jpa/boot-read-replica-postgresql/src/main/java/com/example/demo/readreplica/domain/ArticleDTO.java (1)
16-25: Streamline comment conversion.The loop-based approach works well. For slightly more concise code, consider leveraging streams directly, such as:
commentDTOs.stream() .map(CommentDTO::convertToComment) .forEach(article::addComment);Otherwise, the logic is correct and straightforward as implemented.
jpa/boot-read-replica-postgresql/src/main/java/com/example/demo/readreplica/controller/ArticleController.java (1)
45-53: Consider using 204 (No Content) for successful deletions.
Returning202 Acceptedmay confuse clients if the operation completes immediately rather than asynchronously.ResponseEntity.noContent()is more common for synchronous deletions and signals the resource has been removed.- return ResponseEntity.accepted().build(); + return ResponseEntity.noContent().build();jpa/boot-read-replica-postgresql/src/main/resources/application.yml (2)
48-50: LGTM! Good addition of RFC 7807 Problem Details support.The addition of Problem Details support is a good practice for standardized error responses. This aligns well with REST API best practices and RFC 7807.
Consider implementing a global exception handler (
@ControllerAdvice) to leverage this configuration effectively, especially for the Article-related operations. This will ensure consistent error responses across your API.
48-50: Consider additional Problem Details customization options.You might want to add more problem details configurations for better error handling:
mvc: problemdetails: enabled: true + # Customize the default problem detail fields + messages: + # Use message codes from messages.properties + always-use-message-format: true + # Include message detail for validation errors + validation-errors-as-violations: true

boot-ultimate-redis/src/test/java/com/example/ultimateredis/controller/RedisControllerTest.java (3)
31-31: Great addition to validate the response type.
Using .hasContentType(MediaType.APPLICATION_JSON) ensures the returned content is JSON, improving test coverage and consistency with best practices for RESTful APIs.
46-46: Consistent response type validation.
Verifying that the response is JSON aligns the contract with expectations and ensures reliable data parsing in consumer services.
66-66: Solid check for JSON response format under async conditions.
Confirming the content type in this retry-based test is especially important to ensure consistent behavior in time-sensitive scenarios.
jpa/boot-read-replica-postgresql/src/test/java/com/example/demo/readreplica/controller/ArticleControllerIntTest.java (3)
25-25: Ensure MockMvcTester is a stable and well-documented approach.
Using MockMvcTester is slightly unconventional compared to the default Spring Boot MockMvc. Confirm that it’s correctly configured and documented, so that future contributors can easily maintain the tests.
64-113: Excellent comprehensive test for article lifecycle.
This sequence thoroughly covers creation, retrieval, and deletion, ensuring the entire workflow is valid. Only minor concern is time-based checks using LocalDateTime.now(). Borderline timing in test environments might cause sporadic failures if run near midnight.
117-118: Good edge-case handling for delete on non-existent article.
This test ensures 404 is returned for non-existent resources, improving API reliability. The coverage is appropriate.
jpa/boot-read-replica-postgresql/src/main/java/com/example/demo/readreplica/domain/CommentDTO.java (1)
3-4: No issues with the import statement.
Importing Comment is necessary for the conversion logic. Everything looks good here.
jpa/boot-read-replica-postgresql/src/main/java/com/example/demo/readreplica/domain/ArticleDTO.java (1)
3-4: Static import usage is acceptable.
Using static imports for convertToComment is fine, though some teams prefer explicit references to improve clarity. The current approach is acceptable.
jpa/boot-read-replica-postgresql/src/main/java/com/example/demo/readreplica/service/ArticleService.java (5)
12-12: Transactional usage is appropriate.
Declaring the class-level @Transactional(readOnly = true) ensures that all read operations are in a read-only transaction. It’s a good optimization for read-heavy services.
21-21: Updated ID type to Long.
Switching from Integer to Long is consistent with larger ID ranges. No issues detected.
25-27: Existence check is clear.
This direct delegation to the repository for existence checks is straightforward and promotes clarity. Good choice.
31-31: Conversion method usage looks correct.
Calling articleDTO.convertToArticle() aligns with the new structure. This approach keeps DTO logic isolated from the service and is well-structured.
36-39: Deletion approach is fine.
Utilizing repository-level deleteById is a standard pattern. Ensure that id validity checks or existence checks are handled where needed (likely in the controller), if necessary.
jpa/boot-read-replica-postgresql/src/main/java/com/example/demo/readreplica/repository/ArticleRepository.java (1)
12-12: Validate the removal of @Transactional(readOnly = true) and ID type alignment
Switching from Integer to Long is consistent with typical ID usage in JPA, and the Optional<Article> return type is a good practice. However, confirm whether removing the @Transactional(readOnly = true) annotation was intentional. If the method is only reading data, re-introducing the read-only annotation can yield performance benefits and avoid accidental writes within the same transaction scope.
Would you like me to run a shell script to locate all callers of findByArticleId and confirm that none rely on read-only semantics?
jpa/boot-read-replica-postgresql/src/main/java/com/example/demo/readreplica/controller/ArticleController.java (4)
7-7: No issues found with the new import.
The DeleteMapping annotation import properly facilitates handling HTTP DELETE requests.
14-14: ServletUriComponentsBuilder import is correct.
This import is crucial for constructing self-descriptive resource URIs, improving REST API standards.
37-43: Location URI creation looks good.
Using ServletUriComponentsBuilder for the Location header aligns with standard RESTful best practices. The path expansion is correct for dynamically generating resource URIs.
27-27: Verify consistency of the updated ID type.
Switching from Integer to Long is fine, but ensure downstream code also uses Long.
Here's a script you can run to quickly identify any old references:
✅ Verification successful
ID type is consistently Long across the codebase
Based on the search results, the ID type is consistently using Long throughout the codebase, including:
- The Article entity uses
private Long id - The ArticleRepository methods use
Longfor ID parameters - The ArticleService methods use
Longfor ID parameters - No references to
Integertype for IDs were found
The change from Integer to Long is consistent with the rest of the codebase.

12-12: Verify the impact of artifact ID change on dependent modules.
The artifact ID and name changes from boot-jpa-read-replica-postgresql to boot-read-replica-postgresql look good, making the naming more concise.
Let's verify if there are any modules depending on this artifact:
Also applies to: 14-14
✅ Verification successful
Artifact ID change is safe to proceed
The verification shows that:
- The module is correctly referenced in the root
pom.xmlasjpa/boot-read-replica-postgresql - No other files in the codebase reference the old artifact ID
- The module is properly listed among other JPA-related modules in the
jpadirectory
The artifact ID change is self-contained and doesn't impact any dependent modules.

112-112: Verify compatibility with the updated googleJavaFormat version.
The update to googleJavaFormat version 1.25.2 is a minor version bump that could affect code formatting.
Let's verify the formatting changes by checking the diff after running spotless:
✅ Verification successful
Let me analyze the code formatting impact by checking for any Java files that might be affected by the Google Java Format version change.
Let me try a different approach to check the formatting patterns.
Let me try one final check to verify the impact of the Google Java Format version change.
Based on the analysis of the code samples and formatting patterns, I can now provide a final response about the Google Java Format version update.
The update to googleJavaFormat 1.25.2 appears safe to proceed
The code samples show consistent formatting patterns that align well with Google Java Format's style rules. The examined files demonstrate:
- Clean import statements with proper spacing
- Consistent indentation (2-space)
- Standard method chaining patterns
- Proper class and method declarations
The minor version bump (1.25.2) typically focuses on bug fixes and minor improvements rather than significant formatting changes. The formatting patterns in the codebase appear to follow standard Java conventions that are stable across recent versions of Google Java Format.

💡 Codebase verification
Problem Details enabled but error handling implementation is incomplete
The problem details configuration is enabled in application.yml, but the Article-related components lack proper error handling implementation:
- No custom exceptions defined for Article-related error scenarios
- No global exception handler found in the project
- ArticleService returns Optional but there's no explicit error handling for not-found scenarios
- No ResponseStatusException usage found in the controllers
To properly integrate with Problem Details:
- Create a GlobalExceptionHandler class with @ControllerAdvice
- Define custom exceptions for Article-related error scenarios (e.g., ArticleNotFoundException)
- Handle Optional.empty() cases in the controller by throwing appropriate exceptions
- Consider adding validation error handling
🔗 Analysis chain
Verify error handling integration with Article operations.
Let's verify that the problem details configuration is properly integrated with the Article-related error scenarios.
Let me gather more specific information about the error handling in this project.
Let me check for specific error handling implementations in the Article-related components.
Let me check one more aspect to verify the error handling integration.
