spring事件监听

spring事件监听

ApplicationListener监听容器中发布的事件

实现ApplicationListener来完成事件监听

public interface ApplicationListener<E extends ApplicationEvent> extends EventListener {

   /**
    * Handle an application event.
    * @param event the event to respond to
    */
   void onApplicationEvent(E event);

}

可以使用publishEvent方法来发布事件

ApplicationContext context = new AnnotationConfigApplicationContext(MainConfig4.class);

context.publishEvent(new ApplicationEvent() {
        });
