@RepositoryEventHandler events stop with @RepositoryRestController

Question

When I create a @RepositoryRestController for an entity, the associated @RepositoryEventHandler methods are not triggered in Spring Data REST via S

Answer 1

It's as implemented. :-)

The methods defined in a @RepositoryRestController implementation replace the methods in the default RepositoryEntityController which publish @RepositoryEventHandler events.

But it's easy to add these events making the @RepositoryRestControll a ApplicationEventPublisherAware implementation and publishing the events like the default RepositoryEntityController implementation:

@Slf4j
@RepositoryRestController
@AllArgConstructor
public class AccountRespositoryRestController 
    implements ApplicationEventPublisherAware {

    private final AccountRepository repository;
    private ApplicationEventPublisher publisher;

    @Override
    public void setApplicationEventPublisher(
        ApplicationEventPublisher publisher) {
        this.publisher = publisher;
    }

    @RequestMapping(method = RequestMethod.POST,value = "/accounts")
    public @ResponseBody PersistentEntityResource post(
        @RequestBody Account account,
        PersistentEntityResourceAssembler assembler) {

        // ...
        publisher.publishEvent(new BeforeCreateEvent(account));
        Account entity = this.repository.save(account);
        publisher.publishEvent(new AfterCreateEvent(entity));

        return assembler.toResource(entity);
    }
}

You can also inject the publisher without making the class ApplicationEventPublisherAware:

@Slf4j
@RepositoryRestController
@AllArgConstructor
public class AccountRespositoryRestController {

    private final AccountRepository repository;
    private final ApplicationEventPublisher publisher;

    @RequestMapping(method = RequestMethod.POST,value = "/accounts")
    public @ResponseBody PersistentEntityResource post(
        @RequestBody Account account,
        PersistentEntityResourceAssembler assembler) {

        // ...
        publisher.publishEvent(new BeforeCreateEvent(account));
        Account entity = this.repository.save(account);
        publisher.publishEvent(new AfterCreateEvent(entity));

        return assembler.toResource(entity);
    }
}
