public interface ApplicationListener<E extends ApplicationEvent>
extends java.util.EventListener

Interface to be implemented by application event listeners. Based on the standard java.util.EventListener interface for the Observer design pattern.

As of Spring 3.0, an ApplicationListener can generically declare the event type that it is interested in. When registered with a Spring ApplicationContext, events will be filtered accordingly, with the listener getting invoked for matching event objects only.
