5）ServletRequestListener：

ServletRequestListener能監聽到Request的生成和銷燬。

例 2.2.5.1

package com;
import javax.servlet.ServletRequestEvent;
import javax.servlet.ServletRequestListener;
public class MyServletRequestListener implements
ServletRequestListener {
/*public void requestDestroyed(ServletRequestEvent sre)Notification that the servlet request is about to go out of scope. */
    public void requestDestroyed(ServletRequestEvent arg0) {
        System.out.println("馬克-to-win destroyed"+arg0.getServletRequest().getRemoteAddr());
    }
/*public void requestInitialized(ServletRequestEvent sre)Notification that the servlet request is about to go into scope. */
    public void requestInitialized(ServletRequestEvent arg0) {
        System.out.println("馬克-to-win request Initialized"+arg0.getServletRequest().getRemoteAddr());
    }
}
