根据以前写过的登录，现在来写一下获取总记录数根据上一个继续编写
1.在IUserInfoDAO中编写
1 //2.获取总记录数 2 public int getTotalCount();
IUserInfoDAO.xml
1 <!--2.获取总记录数--> 2 <select id="getTotalCount" resultType="int"> 3 select count(1) from smbms_user 4 </select>
2.Service层
IUserInfoService
1 //2.获取总记录数 2 public int getTotalCount();
Service层下的impl包中定义一个类实现接口IUserInfoServiceImpl
1 @Service("userService") 2 public class UserInfoServiceImpl implements IUserInfoService { 3 4 //植入dao对象 5 @Resource(name = "IUserInfoDAO") 6 IUserInfoDAO userInfoDAO; 7 //2.获取总记录数 8 public int getTotalCount() { 9 return userInfoDAO.getTotalCount(); 10 }
3.controller包下定义的类UserInfoController
1 @Controller 2 public class UserInfoController { 3 //空指针 4 //DI 5 @Resource(name = "userService") 6 IUserInfoService userInfoService; 7 8 @RequestMapping("/isLogin") 9 public String isLogin(UserInfo info){ 10 //引用service 11 UserInfo user = userInfoService.isLogin(info); 12 if (user!=null&&user.getUserName()!=null){ 13 //login success 14 return "welcome"; 15 }else{ 16 return "login"; 17 } 18 } 19 /*让用户看到该视图*/ 20 @RequestMapping("/showUserList") 21 public String showUserList(){ 22 return "userList"; 23 }
4.最后来修改jsp页面
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}/isLogin" method="post"> 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>
