       简介：监听器介绍和Servlet3.0的注解自定义原生Listener监听器实战

       1、自定义Listener(常用的监听器 servletContextListener、httpSessionListener、servletRequestListener)
           @WebListener
           public class RequestListener implements ServletRequestListener {

               // TODO Auto-generated method stub
               System.out.println("======requestDestroyed========");
           }

           @Override
           public void requestInitialized(ServletRequestEvent sre) {
               System.out.println("======requestInitialized========");

           }
