Asynchronous execution of ApplicationListeners through annotation [SPR-3876]

[spring-projects-issues]

Steven Devijver opened SPR-3876 and commented

Attached is a 3-class implementation that lets ApplicationListener implementations execute in an asynchronous fashion:

@Async
public class MyApplicationListener implements ApplicationListener {
public void onApplicationEvent(ApplicationEvent event) {
// do something
}
}

The implementation includes a BPP that detects @Async on ApplicationListeners and wraps them in a decorator with a TaskExecutor. On arrival of an event the onApplicationEvent() method is executed in a seperate thread.

FYI: This is supported if you use the http://static.springframework.org/spring/docs/2.5.x/api/org/springframework/context/event/SimpleApplicationEventMulticaster.html by setting a TaskExecutor - configured on the event submitting side.

#8211 is along the same generic @Async approach as in this request (marking arbitrary methods as @Asynchronous).
