Spring Add error handler for transactional event

Exceptions propagated from the transactional event listener are handled by TransactionSynchronizationUtils and are not rethrown. However, the lack of a configurable error handler for these exceptions makes it difficult to customize exception handling during transactional event processing. To address this, I added an abstract error handler that can be defined as follows:

@Component
public abstract class TransactionalEventErrorHandlerImpl extends TransactionalEventErrorHandler {

    // can inject other beans

    @Override
    public void handle(ApplicationEvent event, @Nullable Throwable ex) {
        // custom logic
    }

}
