Document that @TransactionalEventListener is not supported with ReactiveTransactionManager

[Cepr0]

Affects: Spring Boot 2.2.0.M3

---

If we publish the events within the transactional reactive methods, for example:

@Transactional
public Mono<Model> create(Model model, ModelEvent.Type type) {
    return repo.save(model)
            .doOnSuccess(m -> publisher.publishEvent(new ModelEvent(m, type)));
}

then the 'event listener' method with @TransactionalEventListener is not invoked (regardless of whether the @Async annotation is used or not):

// @Async
@TransactionalEventListener(condition = "#event.inTransactionEventListener()")
public void handleEventInTransactionEventListener(ModelEvent event) {
    log.info("[i] Handled event: {}, in transactional event listener", event.getModel());
}

Related demo is here.

Hi,
any updates on this issue? I'm having this problem with Spring Boot 2.4.0-RC1

Thanks for the nudge and sorry this wasn't triaged earlier. @TransactionalEvenListener only works with imperative transactions, not reactive transaction so we'll have to clarify that in the reference guide and, potentially, the javadoc of related classes.

Hi,
thank you for clarification.

@snicoll Hi.
Is there any plan to support TransactionalEventListener for Reactive ? (like @ReactiveTransactionalEventListener).

[snicoll]

I am afraid not.

As a documentation ticket, this duplicates #25805.

As of 6.1, @TransactionalEventListener can be triggered with reactive transactions through adding the transaction context as the event source: #27515 (comment)
