springboot-@EventListener简单用法

@Component
public class TestEventListener {
    @EventListener(classes = {ApplicationEvent.class})
    public void testEvent(ApplicationEvent event){
        System.out.println("done---->"+event.toString());
    }

//     直接在方法里面进行指定也是可以的。不需要再注解里面设置
//    @EventListener()
//    public void testEvent(ApplicationEvent event){
//        System.out.println("done---->"+event.toString());
//    }

    @EventListener()
    public void testEvent2(ApplicationStartedEvent event){
        System.out.println("done--Even2-->"+event.toString());
    }
}
