Migration Guide 2.3

Dev Mode Working Directory

The working directory for dev mode has been changed from the build directory (target/) to the root of the project. This makes the execution of the tests with continuous testing consistent with the tests executed via Surefire.

To restore the previous behavior, you can define <workingDir>${project.build.directory}</workingDir> in the Quarkus Maven plugin configuration.

gRPC Server Interceptors

Global gRPC server interceptors have to be annotated with @io.quarkus.grpc.GlobalInterceptor since 2.3.

Prior to Quarkus 2.3, all the CDI beans implementing io.grpc.ServerInterceptor where considered global interceptors, i.e. applied to all gRPC services. Since 2.3, it is possible to make a service-specific interceptor, by adding @io.quarkus.grpc.RegisterInterceptor(MyInterceptor.class) on a gRPC service implementation. To easily distinguish between per-service interceptors and global ones, the aforementioned @GlobalInterceptor annotation has been introduced.

CDI @PreDestroy and @PostConstruct methods on bean classes

Fixed a bug where @PreDestroy and @PostConstruct methods declared on bean classes were considered business methods which violated CDI specification rules. Therefore, starting with 2.3, an invocation of these methods will no longer be intercepted by any @AroundInvoke interceptors declared on the bean class and/or on these lifecycle methods.

This means that if you previously leveraged this scenario (for example to apply @Transactional to post construct callback), you will need to change your code. Here is an example of an approach that will still work:

@Dependent
class MyBean {
   @PostConstruct
   void init() {
     doInit(); // Interception works for self-invocation
   }
   
   @Transactional
   void doInit() {
     // ...e.g. save something in DB
   }
}

Deprecated methods in OIDC TokenStateManager

io.quarkus.oidc.TokenStateManager has had its String createTokenState(RoutingContext, OidcTenantConfig, AuthorizationCodeTokens), AuthorizationCodeTokens getTokens(RoutingContext, OidcTenantConfig, String) and void deleteTokens(RoutingContext, OidcTenantConfig, String) methods deprecated and these methods will be removed soon.

Please use Uni<String> createTokenState(RoutingContext, OidcTenantConfig, AuthorizationCodeTokens, CreateTokenStateRequestContext), Uni<AuthorizationCodeTokens> getTokens(RoutingContext, OidcTenantConfig, String, GetTokensRequestContext) and Uni<Void> deleteTokens(RoutingContext, OidcTenantConfig, String, DeleteTokensRequestContext) instead, where the request contexts can be used to run the blocking tasks.

Reactive Routes

The extension artifact id was changed from quarkus-vertx-web to quarkus-reactive-routes, i.e. you should add the following dependency in your pom.xml:

<dependency>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-reactive-routes</artifactId>
</dependency>

NOTE: The original artifact io.quarkus:quarkus-vertx-web is automatically relocated to this new dependency. However, users are encouraged to update the dependency as soon as possible.

New @PersistenceUnitExtension qualifier for TenantResolver/TenantConnectionResolver

Multi-tenancy support in Hibernate ORM relies on user-provided TenantResolver beans, and optionally TenantConnectionResolver beans.

Starting with Quarkus 2.3, you should always use the @PersistenceUnitExtension CDI qualifier for such bean definitions, even when targeting the default persistence unit, and you should never use the @PersistenceUnit CDI qualifier for such bean definitions.

In short, add a @PersistenceUnitExtension annotation for TenantResolver or TenantConnectionResolver beans targeting the default persistence unit:

+ @PersistenceUnitExtension("nameOfMyPersistenceUnit")
  @RequestScoped
  public class CustomTenantResolver implements TenantResolver {
      @Override
      public String resolveTenantId() {
          // ...
      }
  }

And replace the @PersistenceUnit annotation with a @PersistenceUnitExtension annotation for TenantResolver or TenantConnectionResolver beans targeting a named persistence unit:

- @PersistenceUnit("nameOfMyPersistenceUnit")
+ @PersistenceUnitExtension("nameOfMyPersistenceUnit")
  @RequestScoped
  public class CustomTenantResolver implements TenantResolver {
      @Override
      public String resolveTenantId() {
          // ...
      }
  }

Old bean definitions with the old qualifiers will continue to work for now, but such support will be removed in a later version of Quarkus.

Note that @PersistenceUnit is still a valid annotation for injecting EntityManager/EntityManagerFactory in your components; it just shouldn't be used as a CDI qualifier for TenantResolver/TenantConnectionResolver beans.
