EventPublicationInterceptor

public EventPublicationInterceptor()

方法详细资料

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.

抛出:

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)

从接口复制的说明: 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.

指定者:

setApplicationEventPublisher 在接口中 ApplicationEventPublisherAware

参数:

applicationEventPublisher - event publisher to be used by this object

afterPropertiesSet

public void afterPropertiesSet()
                        throws Exception

指定者:

afterPropertiesSet 在接口中 org.springframework.beans.factory.InitializingBean

抛出:

Exception

invoke

public Object invoke(org.aopalliance.intercept.MethodInvocation invocation)
              throws Throwable

指定者:

invoke 在接口中 org.aopalliance.intercept.MethodInterceptor

抛出:

Throwable
