7.连接到数据库   jdbc.properties   用的是MSQ数据库

1 jdbc.driverClassName=com.mysql.jdbc.Driver2 jdbc.url=jdbc:mysql:///smbms3 jdbc.user=root4 jdbc.password=root

8.MyBatis-config.

 1 <?"1.0" encoding="UTF-8" ?> 2 <!DOCTYPE configuration 3   PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 4   ""> 5 <configuration> 6  <!--别名--> 7  <typeAliases> 8   <package name="cn.happy.entity"></package> 9  </typeAliases>10  <!-- &lt;!&ndash;关联小配置&ndash;&gt;11  <mappers>12   <mapper resource="cn/sale/dao/IUserDAO."/>13  </mappers>-->14 </configuration>

9.先修改login.jsp和welcome.jsp

login.jsp

 1 <%@ page pageEncoding="utf-8" isELIgnored="false" %> 2 <!DOCTYPE html> 3 <html> 4 <head lang="en"> 5  <meta charset="UTF-8"> 6  <title>系统登录 - 超市账单管理系统</title> 7  <link rel="stylesheet" href="css/style.css"/> 8 </head> 9 <body class="login_bg">10  <section class="loginBox">11   <header class="loginHeader">12    <h1>超市账单管理系统</h1>13   </header>14   <section class="loginCont">15    <form class="loginForm" action="${pageContext.request.contextPath}/user/doLogin">16     <div class="inputbox">17      <label for="user">用户名：</label>18      <input id="user" type="text" name="userCode" placeholder="请输入用户名" required/>19     </div>20     <div class="inputbox">21      <label for="mima">密码：</label>22      <input id="mima" type="password" name="userPassword" placeholder="请输入密码" required/>23     </div>24     <div class="subBtn">25      <input type="submit" value="登录" />26      <input type="reset" value="重置"/>27     </div>28 29    </form>30   </section>31  </section>32 33 </body>34 </html>
