httpsessiondemo.java

这是用Java写的一个监听器的代码

package cn.mldn.lxh.listener ;

import javax.servlet.http.* ;

public class HttpSessionDemo 
	implements HttpSessionListener,HttpSessionAttributeListener
{
	private HttpSession session ;
	// 实现方法
	public void sessionCreated(HttpSessionEvent se)
	{
		this.session = se.getSession() ;
		System.out.println("** Session 创建 ....") ;
		System.out.println("** SessionID --> "+this.session.getId()) ;
	}
	public void sessionDestroyed(HttpSessionEvent se)
	{
		System.out.println("** Session 销毁 ....") ;
	}
	public void attributeAdded(HttpSessionBindingEvent se)
	{
		System.out.println("** Session 增加属性:"+se.getName()+" --> "+se.getValue()) ;
	}
	public void attributeRemoved(HttpSessionBindingEvent se)
	{
		System.out.println("** Session 删除属性:"+se.getName()+" --> "+se.getValue()) ;
	}
	public void attributeReplaced(HttpSessionBindingEvent se)
	{
		System.out.println("** Session 替换属性:"+se.getName()+" --> "+se.getValue()) ;
	}
};
