1.登录页面的实现（login.jsp）


<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>登录页面</title>
    <link rel="stylesheet" href="./css/style.css" type="text/css">
</head>
<body>
<div class="login-form-wrap">
    <h1>登录页面</h1>
    <form class="login-form" action="/cookie/UserServlet" id="regist" method="get" autocomplete="off">
        <label>
            <input type="text" id="username" name="username" placeholder="Username" value="">
        </label>
        <label>
            <input type="password" id="password" name="password" placeholder="Password" value="">
        </label>
        <input type="submit" value="登录">
        <a href="./regist.jsp">未注册？点击注册</a>
    </form>
</div>
</body>
<script>
    //1.为表单登录绑定提交事件
    document.getElementById("regist").onsubmit = function() {
        //2.获取填写的用户名和密码
        let username = document.getElementById("username").value;
        let password = document.getElementById("password").value;
 
        //3.判断用户名是否符合规则
        let reg1 = /^[a-zA-Z]{4,16}$/;
        if(!reg1.test(username)) {
            alert("用户名不符合规则，请输入4 ~ 16位纯字母！");
            return false;
        }
 
        //4.判断密码是否符合规则
        let reg2 = /^[\d]{6}$/;
        if(!reg2.test(password)) {
            alert("密码不符合规则，请输入6位纯数字密码！");
            return false;
        }
        //5.如果所有条件都不满足，则提交表单
        return true;
    }
</script>
</html>

表单信息提交到UserServlet类


package com.hbsi.controller;
import com.hbsi.bean.User;
import com.hbsi.service.UserService;
import com.hbsi.service.impl.UserServiceImpl;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;
@WebServlet("/UserServlet")
public class UserServlet extends HttpServlet {
    UserService service=new UserServiceImpl();
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        req.setCharacterEncoding("UTF-8");
        resp.setCharacterEncoding("UTF-8");
        resp.setContentType("text/html;charset=UTF-8");
        String username = req.getParameter("username");
        String password = req.getParameter("password");
        User user=new User(username,password);
        User user1= service.selectUsermassage(user);
        //判断用户名
        if(username==null || "".equals(username)) {
            //2.1用户名为空，重定向到登录页面
            resp.sendRedirect("/cookie/login.jsp");
            return;
        }
        //2.2 用户名不为空，将用户名存入到绘话域
        if(user1 !=  null) {
                req.getSession().setAttribute("user1", user1);
                resp.sendRedirect("/cookie/usermassage.jsp");
        }else {
            req.setAttribute("msg","该用户名未注册或密码错误！！！");//封装请求属性
            req.getRequestDispatcher("login.jsp").forward(req,resp);
        }
    }
 
    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        doGet(req, resp);
    }
}

2.注册页面（register.jsp）


 
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>注册页面</title>
    <link rel="stylesheet" href="./css/regist01.css" type="text/css">
