校园商铺-2项目设计和框架搭建-9验证Service

Posted 2022-11-18 csj2018

1. 新建接口

main: com.csj2018.o2o.service/AreaService.java

package com.csj2018.o2o.service;
import java.util.List;
import com.csj2018.o2o.entity.Area;
public interface AreaService 
    List<Area> getAreaList();

2. 新建实现类

main: com.csj2018.o2o.service.impl/AreaService.java

package com.csj2018.o2o.service.impl;

import java.util.List;

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

import com.csj2018.o2o.dao.AreaDao;
import com.csj2018.o2o.entity.Area;
import com.csj2018.o2o.service.AreaService;
@Service
public class AreaServiceImpl implements AreaService
    @Autowired
    private AreaDao areaDao;
    @Override
    public List<Area> getAreaList()
        return areaDao.queryArea();
    

3. 修改基类

test: com.csj2018.o2o/BaseTest.java

package com.csj2018.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启动式加载springIOC容器
 */
@RunWith(SpringJUnit4ClassRunner.class)
//告诉junit spring配置文件的位置
@ContextConfiguration("classpath:spring/spring-dao.xml","classpath:spring/spring-service.xml")
public class BaseTest 

4. 测试类

test: com.csj2018.o2o.service/AreaServiceTest.java

package com.csj2018.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.csj2018.o2o.BaseTest;
import com.csj2018.o2o.entity.Area;

public class AreaServiceTest extends BaseTest
    @Autowired
    private AreaService areaService;
    @Test
    public void testGetAreaList() 
        List<Area> areaList = areaService.getAreaList();
        assertEquals("南苑",areaList.get(0).getAreaName());
    

运行错误，待排查
