maven Spring+Spring MVC+Mybatis+mysql轻量级Java web开发环境搭建

　　之前一直在做的一个GIS系统项目，采用了jsp+servlet框架，数据传输框架采用了apache的thrift框架，短时多传的风格还不错，但是较其他的java web项目显得有点太臃肿了，现在给大家介绍一下最近刚刚研究的轻量级java web框架。

1.首先是创建maven项目

本人开发用的IDE用的是IDEA 2017，Google上这样评价IDEA：最适合开发java程序的IDE，看到这里大家就应该知道了。首先新建一个maven程序，如图

选择从archeType创建，在src-》main文件夹下创建java（resource）文件夹，这样才能在该文件夹下创建java class，同时在java目录下创建如下四个文件夹，分别代表控制器、数据存储处理、对象模型、处理服务。

2.添加maven项目依赖。

pom.xml，各个依赖项所对应的模块名称已注明。

3.在service下创建服务接口类

ITestService.Java

package com.chuyin.service;

import com.alibaba.fastjson.JSONObject;

/**
 * Created by Zhang Feiyue on 2017/7/8.
 */
public interface ITestService {
    public JSONObject getUsers(JSONObject param);
}

4.在service文件夹下创建实现接口方法的类

TestService.Java

package com.chuyin.service.impl;

import com.alibaba.fastjson.JSONObject;
import com.chuyin.mapper.TestMapper;
import com.chuyin.service.ITestService;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import javax.annotation.Resources;
import java.util.List;

/**
 * Created by Zhang Feiyue on 2017/7/8.
 */
@Service
public class TestService implements ITestService {
    @Resource
    private TestMapper testMapper;

    @Override
    public JSONObject getUsers(JSONObject param) {
        List<JSONObject> userList = testMapper.getUsers(param);
        JSONObject result = new JSONObject();
        result.put("userList", userList);
        return result;
    }
}

5.在mapper文件夹下创建数据获取接口类

TestMapper.Java

package com.chuyin.mapper;

import com.alibaba.fastjson.JSONObject;
import org.springframework.stereotype.Component;

import java.util.List;

/**
 * Created by Zhang Feiyue on 2017/7/8.
 */
@Component
public interface TestMapper {
    public List<JSONObject> getUsers(JSONObject param);
}

6.创建控制器实现类

TestController.Java

package com.chuyin.controller;

import com.alibaba.fastjson.JSONObject;
import com.chuyin.service.impl.TestService;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;

/**
 * Created by Zhang Feiyue on 2017/7/8.
 */
@RestController
@RequestMapping("/test")
public class TestController {
    @Resource
    private TestService testService;

    @RequestMapping(value = "/getUser", method = RequestMethod.POST)
    public JSONObject getUser(@RequestBody JSONObject param) {
        JSONObject result = testService.getUsers(param);
        result.put("success", true);
        return result;
    }
}

7.resources文件下创建文件夹，并配置TestMapper.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.chuyin.mapper.TestMapper">
    <select id="getUsers" parameterType="JSON" resultType="JSON">
        <![CDATA[
        select * from base_user where username=#{username}
        ]]>
    </select>
</mapper>

8.创建application.properties文件，配置jdbc

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/chuyin
jdbc.username=root
jdbc.password=root

9.配置log4j.xml,mybatis-config.xml,spring-common.xml,spring-mvc.xml

log4j.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration PUBLIC "-//LOGGER" "log4j.dtd">

好了，至此后台已全部配置完毕，看一下效果吧，可以看到数据已经获取成功。
