一个相对比较简单的留言簿！功能还比较齐全！

package com.pure35.servlet;

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 Logout extends HttpServlet {

	private static final long serialVersionUID = 1L;

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

		this.doPost(request, response);
	
	}

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

		//使用户session失效
		HttpSession session=request.getSession();
		session.invalidate();
		
		//提示信息
		//TODO  添加提示信息代码
		
		//跳转到登陆页面
		request.getRequestDispatcher("login.jsp").forward(request, response);
		
	}
