All Implemented Interfaces:
Advice, Interceptor, MethodInterceptor, Aware, InitializingBean, ApplicationEventPublisherAware
```
public class EventPublicationInterceptor
extends Object
implements MethodInterceptor, ApplicationEventPublisherAware, InitializingBean
```
Interceptor that publishes an ApplicationEvent to all ApplicationListeners registered with an ApplicationEventPublisher after each successful method invocation.
Note that this interceptor is only capable of publishing stateless events configured via the "applicationEventClass" property.

public EventPublicationInterceptor()
```
- Method Detail
  - setApplicationEventClass
```
public void setApplicationEventClass(Class<?> applicationEventClass)
```
    Set the application event class to publish.
    The event class must have a constructor with a single Object argument for the event source. The interceptor will pass in the invoked object.
    Throws:
    IllegalArgumentException - if the supplied Class is null or if it is not an ApplicationEvent subclass or if it does not expose a constructor that takes a single Object argument
  - setApplicationEventPublisher
```
public void setApplicationEventPublisher(ApplicationEventPublisher applicationEventPublisher)
```
    Description copied from interface: ApplicationEventPublisherAware
    Set the ApplicationEventPublisher that this object runs in.
    Invoked after population of normal bean properties but before an init callback like InitializingBean's afterPropertiesSet or a custom init-method. Invoked before ApplicationContextAware's setApplicationContext.
    Specified by:
    setApplicationEventPublisher in interface ApplicationEventPublisherAware
    Parameters:
    applicationEventPublisher - event publisher to be used by this object
  - afterPropertiesSet
```
public void afterPropertiesSet()
                        throws Exception
```
    Description copied from interface: InitializingBean
    Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.
    This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
    Specified by:
    afterPropertiesSet in interface InitializingBean
    Throws:
    Exception - in the event of misconfiguration (such as failure to set an essential property) or if initialization fails for any other reason
  - invoke
```
public Object invoke(MethodInvocation invocation)
              throws Throwable
```
    Description copied from interface: MethodInterceptor
    Implement this method to perform extra treatments before and after the invocation. Polite implementations would certainly like to invoke Joinpoint.proceed().
    Specified by:
    invoke in interface MethodInterceptor
    Parameters:
    invocation - the method invocation joinpoint
    Returns:
    the result of the call to Joinpoint.proceed(); might be intercepted by the interceptor
    Throws:
    Throwable - if the interceptors or the target object throws an exception
