SSM到Spring Boot-從零開發校園商鋪平臺二（SSM框架搭建配置與驗證）

配置Maven

通過maven引入項目所需要的的架包，編寫pom.xml文件

逐層完成SSM的各項配置

編輯jdbc.properties並保存在src/main/resources目錄下

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/o2o?useUnicode=true&characterEncoding=utf8
jdbc.username=toot

驗證DAO

package com.imooc.o2o.dao;

import java.util.List;

import com.imooc.o2o.entity.Area;

public interface AreaDao {

    /*
     * 列出區域列表
     * @return areaList
     */
    List<Area> queryArea();
}

src/main/resources/mapper路徑下創建AreaDao.xml文件

<?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.imooc.o2o.dao.AreaDao">

 <select id="queryArea" resultType="com.imooc.o2o.entity.Area">
        SELECT

        area_name,

        FROM
        tb_area
        ORDER BY
        priority DESC
    </select>

</mapper>

package com.imooc.o2o;

import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/*
 * 配置spring和junit整合，junit啓動時加載springIOC容器
 */
@RunWith(SpringJUnit4ClassRunner.class)
//告訴junit spring配置文件的位置
@ContextConfiguration({"classpath:spring/spring-dao.xml"})
public class BaseTest {

}

package com.imooc.o2o.dao;

import com.imooc.o2o.BaseTest;
import com.imooc.o2o.entity.Area;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;


import java.util.List;

import static junit.framework.TestCase.assertEquals;


public class AreaDaoTest  extends BaseTest {
    @Autowired
    private AreaDao areaDao;
    @Test
    public void queryArea() {
        List<Area> list = areaDao.queryArea();
        assertEquals(3,list.size());
    }
}

run as運行測試文件，JUnit進度條綠色，測試通過。

驗證Service

com.imooc.o2o.service路徑下創建interface文件AreaService.java

package com.imooc.o2o.service;

import java.util.List;

import com.imooc.o2o.entity.Area;

public interface AreaService {

    List<Area> getAreaList();
}

com.imooc.o2o.service.impl路徑下創建class文件AreaServiceImpl.java

package com.imooc.o2o.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.imooc.o2o.dao.AreaDao;
import com.imooc.o2o.entity.Area;
import com.imooc.o2o.service.AreaService;

@Service
public class AreaServiceImpl implements AreaService{

    @Autowired
    private AreaDao areaDao;
    @Override
    public List<Area> getAreaList() {

        return areaDao.queryArea();
    }
}

com.imooc.o2o路徑下創建com.imooc.o2o.service包，再創建測試類AreaServiceTest.java

package com.imooc.o2o.service;

import static org.junit.Assert.assertEquals;

import java.util.List;

import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;

import com.imooc.o2o.BaseTest;
import com.imooc.o2o.entity.Area;

public class AreaServiceTest extends BaseTest{

    @Autowired
    private AreaService areaService;
    @Test
    public void testGetAreaList() {
        List<Area> areaList = areaService.getAreaList();
        assertEquals("西苑", areaList.get(0).getAreaName());
    }
}

修改BaseTest.java文件

package com.imooc.o2o;

import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/*
 * 配置spring和junit整合，junit啓動時加載springIOC容器
 */
@RunWith(SpringJUnit4ClassRunner.class)
//告訴junit spring配置文件的位置
@ContextConfiguration({"classpath:spring/spring-dao.xml","classpath:spring/spring-service.xml"})
public class BaseTest {

}

測試通過。

驗證Controller

創建com.imooc.o2o.web.superadmin包，下面創建AreaController.java類
