首先创建一个servlet接受和处理请求：
package com.atm.servlet;import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.annotation.*;
import java.io.IOException;//用户退出
@WebServlet("/logout")
public class ExitServlet extends HttpServlet {@Overrideprotected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//销毁session对象，或销毁session中保存的用户数据// request.getSession().removeAttribute("ua");request.getSession().invalidate();response.sendRedirect("/changepage/login.jsp");}@Overrideprotected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {doPost(request,response);}
}
对前端页面进行修改：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page language="java"%>
<%@ page import="java.util.*"%>
<%@ page import="java.text.*"%>
