之前一直在做的一個GIS系統項目，採用了jsp+servlet框架，數據傳輸框架採用了apache的thrift框架，短時多傳的風格還不錯，但是較其他的java web項目顯得有點太臃腫了，現在要跟大家介紹一下最近剛研究的輕量級java web框架。
1.首先是建立maven專案
本人開發用的IDE用的是IDEA 2017，Google上這樣評價IDEA：最適合開發java程式的IDE，看到這裡大家就應該知道了。首先新建一個maven程序，如圖
#選擇從archeType創建，在src-》main資料夾下建立java（resource）資料夾，這樣才能在該資料夾下建立java class，同時在java目錄下建立如下四個資料夾，分別代表控制器、資料儲存處理、物件模型、處理服務。
#2.新增maven專案依賴。
pom.xml，各個相依性所對應的模組名稱已註明。

3.在service下建立服務介面類別
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資料夾下建立實作介面方法的類別
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資料夾下建立資料取得介面類別
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.建立控制器實作類別
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檔案下建立資料夾，並設定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.建立application.properties文件，設定jdbc
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/chuyin jdbc.username=root jdbc.password=root
9.設定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，至此後台已全部配置完畢，看一下效果吧，可以看到資料已經取得成功。
