Class EventPublicationInterceptor

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.

    • 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.

      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
      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
      Exception - in the event of misconfiguration (such as failure to set an essential property) or if initialization fails for any other reason
    • invoke

      @Nullable 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
      invocation - the method invocation joinpoint
      the result of the call to Joinpoint.proceed(); might be intercepted by the interceptor
      Throwable - if the interceptors or the target object throws an exception
