一、退出

1、新建退出的 servlet

package com.wyx.ces.controller;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

public class LogoutServlet extends HttpServlet
{
	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException
	{
		HttpSession session = request.getSession();
		// 销毁session
		session.invalidate();
		String rpath = request.getContextPath();
		response.sendRedirect(rpath + "/login.jsp");
	}

	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException
	{

	}
}

2、在 web.xml 当中配置退出 servlet

<servlet>
		<servlet-name>LogoutServlet</servlet-name>
<servlet-class>com.wyx.ces.controller.LogoutServlet</servlet-class>
</servlet>
<servlet-mapping>
	<servlet-name>LogoutServlet</servlet-name>
	<url-pattern>/LogoutServlet</url-pattern>
</servlet-mapping>
