Hello Spring Team!

I have a problem: In my project, I need use @TransactionalEventListener to handle the Cached-Objects to synchronization，in my demo project, I found a problem: If your need use @Transaction in TestCase method, you need to auto-rollback the testing data! so you must be use@Transaction, but now, @TransactionalEventListener it's not work! OMG! I think so is a bug? WHY CANNOT USE @Transactional TO TESTING @TransactionalEventListener ? Is this a reasonable situation?

Show my demo code:

DemoServiceImpl.java

@Service
public class DemoServiceImpl implements DemoService {

    final ApplicationEventPublisher applicationEventPublisher;

    public DemoServiceImpl(ApplicationEventPublisher applicationEventPublisher) {
        this.applicationEventPublisher = applicationEventPublisher;
    }

    @Transactional
    @Override
    public void test() throws SQLException {
        applicationEventPublisher.publishEvent("Demo Test!");
        applicationEventPublisher.publishEvent(Integer.MAX_VALUE);
        throw new SQLException("Test exception");
    }
}

DemoEventReceiverComponentImpl.java

@Service
//@Component
public class DemoEventReceiverComponentImpl implements DemoEventReceiverComponent {

//    @EventListener
    @TransactionalEventListener(phase = TransactionPhase.AFTER_COMMIT, fallbackExecution = false)
    public void onEvent(String data) {
        System.out.println(data);
    }

    //    @EventListener
    @TransactionalEventListener(phase = TransactionPhase.AFTER_COMMIT, fallbackExecution = false)
    public void onEvent2(Integer data) {
        System.out.println(data);
    }
}

DemoServiceImplTest.java

@SpringBootTest
class DemoServiceImplTest {

    @Autowired
    DemoService demoService;

    @Transactional  // Look at this!!! If you comment this line, onEvent*() it's to work!
    @Test
    void test1() throws SQLException {
        demoService.test();
    }
}

[Crying] It took me two days to find out the problem. It was too confusing. I cant say why not? Is there any other solution?

The root cause of this problem is: @Transactional in TestCase it to be rollback transaction! onEvent*() is can't calling exection. Why not improve it so that it can be tested normally.
