Class ApplicationListenerMethodTransactionalAdapter

java.lang.Object

org.springframework.context.event.ApplicationListenerMethodAdapter

org.springframework.transaction.event.ApplicationListenerMethodTransactionalAdapter

All Implemented Interfaces:

java.util.EventListener, ApplicationListener<ApplicationEvent>, GenericApplicationListener, Ordered

class ApplicationListenerMethodTransactionalAdapter
extends ApplicationListenerMethodAdapter

GenericApplicationListener adapter that delegates the processing of an event to a TransactionalEventListener annotated method. Supports the exact same features as any regular EventListener annotated method but is aware of the transactional context of the event publisher.

Processing of TransactionalEventListener is enabled automatically when Spring's transaction management is enabled. For other cases, registering a bean of type TransactionalEventListenerFactory is required.
