同学好，请问具体的信息是什么，应该是你的配置没配对，请按照视频的配置来

1.BaseTest里将两个xml文件给配置上

BaseTest.java

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启动时加载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",
		"classpath:spring/spring-redis.xml" })
public class BaseTest {

}

2.ShopServiceImpl头部记得加

@Service

标签

3.测试类记得写好，该加的标签加上

ShopServiceTest.java

package com.imooc.o2o.service;

import static org.junit.Assert.assertEquals;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.InputStream;
import java.util.Date;

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

import com.imooc.o2o.BaseTest;
import com.imooc.o2o.dto.ImageHolder;
import com.imooc.o2o.dto.ShopExecution;
import com.imooc.o2o.entity.Area;
import com.imooc.o2o.entity.PersonInfo;
import com.imooc.o2o.entity.Shop;
import com.imooc.o2o.entity.ShopCategory;
import com.imooc.o2o.enums.ShopStateEnum;
import com.imooc.o2o.exceptions.ShopOperationException;

public class ShopServiceTest extends BaseTest {
	@Autowired
	private ShopService shopService;

	@Test
	public void testGetShopList() {
		Shop shopCondition = new Shop();
		ShopCategory sc = new ShopCategory();
		sc.setShopCategoryId(3L);
		shopCondition.setShopCategory(sc);
		ShopExecution se = shopService.getShopList(shopCondition, 2, 2);
		System.out.println("店铺列表数为：" + se.getShopList().size());
		System.out.println("店铺总数为：" + se.getCount());
	}

	@Test
	@Ignore
	public void testModifyShop() throws ShopOperationException, FileNotFoundException {
		Shop shop = new Shop();
		shop.setShopId(1L);
		shop.setShopName("修改后的店铺名称");
		File shopImg = new File("/Users/baidu/work/image/dabai.jpg");
		InputStream is = new FileInputStream(shopImg);
		ImageHolder imageHolder = new ImageHolder("dabai.jpg", is);
		ShopExecution shopExecution = shopService.modifyShop(shop, imageHolder);
		System.out.println("新的图片地址为：" + shopExecution.getShop().getShopImg());
	}

	@Test
	@Ignore
	public void testAddShop() throws ShopOperationException, FileNotFoundException {
		Shop shop = new Shop();
		PersonInfo owner = new PersonInfo();
		Area area = new Area();
		ShopCategory shopCategory = new ShopCategory();
		owner.setUserId(1L);
		area.setAreaId(2);
		shopCategory.setShopCategoryId(1L);
		shop.setOwner(owner);
		shop.setArea(area);
		shop.setShopCategory(shopCategory);
		shop.setShopName("测试的店铺3");
		shop.setShopDesc("test3");
		shop.setShopAddr("test3");
		shop.setPhone("test3");
		shop.setCreateTime(new Date());
		shop.setEnableStatus(ShopStateEnum.CHECK.getState());
		shop.setAdvice("审核中");
		File shopImg = new File("/Users/baidu/work/image/xiaohuangren.jpg");
		InputStream is = new FileInputStream(shopImg);
		ImageHolder imageHolder = new ImageHolder(shopImg.getName(), is);
		ShopExecution se = shopService.addShop(shop, imageHolder );
		assertEquals(ShopStateEnum.CHECK.getState(), se.getState());
	}

}

4.spring-service.xml文件配置也请检查一下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx.xsd">
    <!-- 扫描service包下所有使用注解的类型 -->
    <context:component-scan base-package="com.imooc.o2o.service" />

    <!-- 配置事务管理器 -->
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!-- 注入数据库连接池 -->
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!-- 配置基于注解的声明式事务 -->
    <tx:annotation-driven transaction-manager="transactionManager" />
</beans>

总之，请同学仔细比对好视频，程序说1是1，不可能大家的行偏偏同学的不行，肯定是哪里写错了，请仔细检查，下次也请同学附上详细的信息方便定位问题
