junit 单元测试事务自动回滚

junit 单元测试事务会自动回滚。通过@Rollback(true)注解来实现，默认是true，事务会回滚，可以不写。false时事务不会回滚，数据会写到数据库中。

实例：

 

package com.xiaolyuh.service;

import java.util.Date;

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.annotation.Rollback;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.transaction.annotation.Transactional;

import com.alibaba.fastjson.JSON;
import com.xiaolyuh.entity.RewardCouponDetail;
import com.xiaolyuh.mapper.RewardCouponDetailMapper;

@RunWith(SpringRunner.class)
@SpringBootTest
public class RewardCouponDetailServiceTest{

  private static final Logger logger = LoggerFactory.getLogger(RewardCouponDetailServiceTest.class);
  
  @Autowired
  private RewardCouponDetailMapper rewardCouponDetailMapper;
    
    
  @Test
  @Transactional
  @Rollback(true)// 事务自动回滚，默认是true。可以不写
  public void TestCustomer(){
    RewardCouponDetail rewardCouponDetail = new RewardCouponDetail();
    rewardCouponDetail.setRewardInfoId(1L);
    rewardCouponDetail.setCouponId("1");
    rewardCouponDetail.setCouponDetailId(1L);
    rewardCouponDetail.setCreateTime(new Date());
    rewardCouponDetailMapper.insert(rewardCouponDetail);
    logger.info(JSON.toJSONString(rewardCouponDetail));
    Assert.assertNotNull(rewardCouponDetail.getId());
  }
  
}
