1、创建一个maven Project项目如下图：步骤 File->New->others搜索maven
2、按照上面教程，即可创建出一个Maven项目，项目结构如下图
3、将JRE版本设置为1.8，可使用默认的或者自己导入
4、配置 pom.xml
1 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 2 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

7、在src/main/java添加如下包
8、代码开始
（1）dto层 UserDto
package com.lyy.dto; public class UserDto { private Integer userid;//用户id private String username;//用户名 public Integer getUserid() { return userid; } public void setUserid(Integer userid) { this.userid = userid; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } }
(2)dao层 UserDao
package com.lyy.dao; import java.util.List; import org.apache.ibatis.annotations.Param; import org.apache.ibatis.annotations.Select; import com.lyy.dto.UserDto; public interface UserDao { List<UserDto> findByAll(@Param("pageSize")Integer pageSize,@Param("page")Integer page); }
（3）mapper层 UserMapper.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" > <mapper namespace="com.lyy.dao.UserDao" > <resultMap id="userMap" type="com.lyy.dto.UserDto"> <result column="userid" property="userid"/> <result column="username" property="username"/> </resultMap> <!-- 查询用户--> <select id="findByAll" resultMap="userMap"> SELECT u.userid,u.username from lv_user u where u.deleted=0 and u.flag=1 <if test="pageSize!=null and page!=null"> LIMIT #{page},#{pageSize} </if> </select> </mapper>
（4）service层 UserService
package com.lyy.service; import java.util.List; import com.lyy.dto.UserDto; public interface UserService { List<UserDto> findByAll(Integer pageSize,Integer page); }
（5）业务实现层 UserServiceImpl
package com.lyy.serviceimpl; import java.util.List; import javax.annotation.Resource; import org.springframework.stereotype.Service; import com.lyy.dao.UserDao; import com.lyy.dto.UserDto; import com.lyy.service.UserService; @Service public class UserServiceImpl implements UserService { @Resource private UserDao userDao; public List<UserDto> findByAll(Integer pageSize, Integer page) { Integer pageSizes=pageSize==null?10:pageSize; Integer pages=page==null?0:(page-1)*pageSizes; return userDao.findByAll(pageSizes, pages); } public UserDto userListDatil(Integer userid) { return userDao.userListDatil(userid); } }
(6)UserController代码 UserController
package com.lyy.controller; import java.util.List; import javax.annotation.Resource; import javax.servlet.http.HttpServletRequest; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import com.lyy.base.BasicResult; import com.lyy.dto.UserDto; import com.lyy.service.UserService; @Controller @RequestMapping("user") public class UserController { @Resource private UserService userService;
@RequestMapping("/userList") public String userList(HttpServletRequest request,Model model,Integer pageSize,Integer page){ List<UserDto> uList = userService.findByAll(pageSize, page); model.addAttribute("uList", uList); return "userList"; } }
8、在WEB-INF添加一个jsp文件夹
jsp文件夹下添加 userList.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <html> <head> <title>用户</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> </head> <body> <table> <tr> <td> 用户名称</td> <td> 用户id</td> </tr> <c:forEach items="${uList}" var="u"> <tr> <td> ${u.username} <td> <td> ${u.userid} </td> </tr> </c:forEach> </table> </body> </html>
