场景

老大修改我的代码规范时加了它

作用描述

Spring中的@Transactional(rollbackFor = Exception.class)事务处理，当你的方法中抛出异常时，它会将事务回滚到进入此方法前的状态，数据库中的数据将不会改变。

举个栗子

[@Service](https://my.oschina.net/service)public class HexCaseConfServiceImpl implements HexCaseConfService {[@Resource](https://my.oschina.net/u/929718)private HexPmsCaseConfMapper hexPmsCaseConfMapper;@Transactional(rollbackFor = Throwable.class)[@Override](https://my.oschina.net/u/1162528)public MessageResult removeHexPmsCaseConf(String[] noticeIds) throws Exception { 	...	}}
