All Implemented Interfaces:

ApplicationEventMulticaster, BeanFactoryAware

public class ScopeApplicationEventMulticaster

extends SimpleApplicationEventMulticaster

implements BeanFactoryAware

EventMulticaster that propagates events not only to singletons and prototypes instantiated on startup of type ApplicationListener (default behaviour of Spring) but also to listeners (managed beans) in session and request scope.

Listeners in session scope will be instantiated even if they are not instantiated yet; listeners in request scope will not be instantiated if they are not instantiated yet.
