#### 事件监听者角色

`ApplicationListener` 充当了事件监听者角色，它是一个接口，里面只定义了一个 `onApplicationEvent（）`方法来处理`ApplicationEvent`。`ApplicationListener`接口类源码如下，可以看出接口定义看出接口中的事件只要实现了 `ApplicationEvent`就可以了。所以，在 Spring 中我们只要实现 `ApplicationListener` 接口的 `onApplicationEvent()` 方法即可完成监听事件

`ApplicationEventPublisher` 接口的`publishEvent（）`这个方法在`AbstractApplicationContext`类中被实现，阅读这个方法的实现，你会发现实际上事件真正是通过`ApplicationEventMulticaster`来广播出去的。具体内容过多，就不在这里分析了，后面可能会单独写一篇文章提到。
