getApplicationListeners中会根据事件监听器对象和事件类型在多播器的监听器对象中查找满足条件的事件监听器对象,并进行缓存。 invokeListener 先判断是否有设置错误处理程序,如果有则需要用错误处理程序来处理事件监听器中发生的异常。代码如下: protected void invokeListener(ApplicationListener<?> listener, ApplicationEvent...

then the array may contain inner PropertyChangeListeners which are also PropertyChangeListenerProxy objects. If the calling method is interested in retrieving the named property then it would have to test the element to see if it is a proxy class....
If you have read any of the component how-to pages, you probably already know the basics of event listeners. Let us look at one of the simplest event handling examples possible. It is called Beeper, and it features a button that beeps when you click it. Click the Launch button to run...
