Eclipse+Maven+SpringMVC+Mybatis+MySql搭建总结

安装配置Maven省略

 

新建Maven项目,选择maven-archetype-webapp，填写GroupID和ArtifactID

 

修改pom.xml

建好项目结构包

com.zns.controller

com.zns.service

com.zns.mapper

com.zns.domain

 

在com.zns.mapper下新建xmls文件夹用于存放mapper xml文件

 

假设数据库有一张用户表 就2个字段 主键 和 账号

 

新建User类

package com.zns.domain;
 
 
public class User {
    private int UserID;
    private String UserAccount;
     
    public int getUserID() {
        return UserID;
    }
    public void setUserID(int userID) {
        UserID = userID;
    }
    public String getUserAccount() {
        return UserAccount;
    }
    public void setUserAccount(String userAccount) {
        UserAccount = userAccount;
    }       
}

 

 

新建UserMapper接口

package com.zns.mapper;

import com.zns.domain.User;

public interface UserMapper {
    public User getByID(int id);
}

 

 

新建UserMapper xml文件(在mapperxml包下新建)

<?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.zns.mapper.UserMapper">
    <select id="getByID" parameterType="int"
        resultType="com.zns.domain.User">
        select UserID,UserAccount from users where UserID=#{UserID}
    </select>
</mapper>

 

 

新建UserService

package com.zns.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.zns.domain.User;
import com.zns.mapper.UserMapper;

@Service
public class UserService {
    @Autowired
    private UserMapper userMapper;

    public User getByID(int id) {
        return userMapper.getByID(id);
    }
}

 

 

src/main/resources下新建如下结构的配置文件

src/main/resources

  mybatis

      mybatis-config.xml

  spring

     spring-context.xml

     spring-mvc.xml

     spring-mybatis.xml

  jdbc.properties 

 

jdbc.properties内容为

jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/mydb1?useUnicode=true&characterEncoding=utf-8
jdbc.username = root
jdbc.password =123456

 

mybatis-config.xml内容为

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>
    <!-- 返回resultType为map时，如果数据为空的字段，则该字段会省略不显示， 可以通过添加该配置，返回null -->
    <settings>
        <setting name="callSettersOnNulls" value="true" />
    </settings>
</configuration>

在src/main/webapp/WEB-INF下新建views/user/detail.jsp对应目录和文件

detail.jsp内容为

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!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=UTF-8">
<title>user detail</title>
</head>
<body>
    id为： ${userInfo.userID}
</body>
</html>

 

 

新建UserController

package com.zns.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.zns.domain.User;
import com.zns.service.UserService;

@Controller
@RequestMapping("/User")
public class UserController {
    @Autowired
    private UserService userService;

    @RequestMapping("/Detail1")
    public String Detail1(ModelMap modelMap, int id) throws Exception {
        User user = userService.getByID(id);
        modelMap.addAttribute("userInfo", user);
        return "/user/detail";
    }

    @RequestMapping("/Detail2")
    public @ResponseBody Object Detail2(int id) throws Exception {
        User user = userService.getByID(id);
        return user;
    }
}

 

 

启动项目访问测试

http://localhost/myproject/User/Detail1?id=10  跳转到jsp页面

http://localhost/myproject/User/Detail2?id=10  返回json数据

 

 

基本搭建完毕...
