三、web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"

</session-config>

    </web-app>

四、建立本地数据库

库名：OrderDatabase

表名：user

字段

添加一条数据

五、编写代码

1、项目结构

在src/main/java下新建com.zp.test包

2、entity包下编写实体类

package com.zp.test.entity;

public class User {

    private int user_id;

    private String user_name;

    private String password;

    private String phoneNumber;

    private String image_address;

    private String email;

    private String province;

    private String city;

    private int user_status; 

    private int limit;

    private int isdel;

    private String erweima;

    public int getUser_id() {
        return user_id;
    }

    public void setUser_id(int user_id) {
        this.user_id = user_id;
    }

    public String getUser_name() {
        return user_name;
    }

    public void setUser_name(String user_name) {
        this.user_name = user_name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getPhoneNumber() {
        return phoneNumber;
    }

    public void setPhoneNumber(String phoneNumber) {
        this.phoneNumber = phoneNumber;
    }

    public String getImage_address() {
        return image_address;
    }

    public void setImage_address(String image_address) {
        this.image_address = image_address;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getProvince() {
        return province;
    }

    public void setProvince(String province) {
        this.province = province;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public int getUser_status() {
        return user_status;
    }

    public void setUser_status(int user_status) {
        this.user_status = user_status;
    }

    public int getLimit() {
        return limit;
    }

    public void setLimit(int limit) {
        this.limit = limit;
    }

    public int getIsdel() {
        return isdel;
    }

    public void setIsdel(int isdel) {
        this.isdel = isdel;
    }

    public String getErweima() {
        return erweima;
    }

    public void setErweima(String erweima) {
        this.erweima = erweima;
    }

}

3、sql包下编写sql语句

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
 <!DOCTYPE mapper
    PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
    "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.zp.test.dao.UserDao">

    <select id="selectUser" resultType="com.zp.test.entity.User" parameterType="map">
        SELECT * FROM user where user_id = #{user_id}
    </select>

</mapper>

4、dao包下编写Dao

package com.zp.test.dao;

import java.util.List;
import java.util.Map;
import com.zp.test.entity.User;

public interface UserDao {

    public List<User> selectUser(Map<String,Object> map);   

}

5、service包下编写service

package com.zp.test.service;

import java.util.List;
import java.util.Map;

import com.zp.test.entity.User;

public interface UserService {

    public List<User> selectUser(Map<String,Object> map);

}

6、serviceImpl包下编写serviceImpl

package com.zp.test.service.serviceImpl;

import java.util.List;
import java.util.Map;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.zp.test.dao.UserDao;
import com.zp.test.entity.User;
import com.zp.test.service.UserService;

@Service
public class UserServiceImpl implements UserService{

    @Resource
    private UserDao ud;

    @Override
    public List<User> selectUser(Map<String, Object> map) {

        return ud.selectUser(map);
    }

}

7、controller包下编写controller

package com.zp.test.controller;

import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.zp.test.entity.User;
import com.zp.test.service.UserService;

@Controller
@RequestMapping("/userinfo")
public class UserController {

      @Resource
      private UserService us;

      @RequestMapping(value="/{id}")
      @ResponseBody
      public List<User> test(@PathVariable Long id,HttpServletRequest request,HttpServletResponse response){

          System.out.println(id);

          Map<String,Object> paramMap=new HashMap<String,Object>();
          paramMap.put("user_id", id);
          List<User> ulist = us.selectUser(paramMap);
          for(User u : ulist){
              System.out.println(u.getUser_name());
          }
          return ulist;
      }

}

8、编写index.jsp页面

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<script type="text/javascript" src="static/js/jquery-1.10.1.min.js"></script>
<script>
function test1(){

    $.ajax({
         url:"/test2/userinfo/5",
         data:{},
         type:"post",
         dataType:"json",
         success:function(data){
             alert("success");
             alert(data[0].user_name);
         },
         error:function(){
             alert("error");
         }
     });

}

function test2(){
    window.location.href="test2.jsp";
}

</script>
<body>
<input type="button" value="test1" onclick="test1();"/>
<input type="button" value="test2" onclick="test2();"/>
</body>
</html>

六、运行项目，进入欢迎页，点击test1

返回查询结果，与步骤四中数据库表中数据一致，证明搭建成功
