简介：事物的注解咱们能够注解在类上也能够注解在方法上。默认事物的注解@Transactional（propagation=Propagation.REQUIRED，rollbackFor = {RuntimeException.class}，timeout=30）这是默认的事物即你在类或者方法上注解@Transactional后默认会是上面的注解spring
propagation =Propagation.REQUIRED //默认事物传播行为sql
rollbackFor={RuntimeException.class}// 设置须要进行回滚的异常类数组，当方法中抛出指定异常数组中的异常时，则进行事务回滚。数据库
1、首先保证你的配置事物的配置文件正确，咱们的配置文件以下：apache

2、若是配置文件对了，类或者方法上注解了@Transaction 可是注解事物仍是不起做用，批量提交后，不回滚，
解决方法一：不要对方法进行try{}catch(Exception e){}操做
解决方法二：若是对方法进行try{}catch(Exception e){ throw new RuntimeException("运行时出错！")} 必定要抛出运行异常。
3、下面是我功能测试代码:
/**
* 功能描述：汇总清单表数据到sp_stat_other表中
* @author pankx
* @date 2016年5月13日 上午10:48:42
* @param
* @return void
*/
@Transactional(propagation=Propagation.REQUIRED,rollbackFor = {RuntimeException.class, Exception.class})
public boolean sumDataToSpstatother(String month) {
//获取清单表汇总数据
List<Map<String,Object>> spdata = null;
try{
spdata =countRecordByMonth(month);
SpStatOther spStatOther =null;
// int i=0;
if(spdata!=null && spdata.size()>0){
for(Map<String,Object> data:spdata){
spStatOther = new SpStatOther();
/* if(i==2){ 注释是测试事物的
spStatOther.setMonth(month);
spStatOther.setPartyId(data.get("PARTY_ID").toString());
//spStatOther.setSvcCode(SVC_CODE);
spStatOther.setSpServiceId(Long.valueOf(data.get("SP_SERVICE_ID").toString()));
spStatOther.setCallNum(Long.valueOf(data.get("CALL_NUM").toString()));
spStatOther.setDealDate(new Date());
spStatOtherMapper.insertSelective(spStatOther);
}else{*/
spStatOther.setMonth(month);
spStatOther.setPartyId(data.get("PARTY_ID").toString());
spStatOther.setSvcCode(SVC_CODE);
spStatOther.setSpServiceId(Long.valueOf(data.get("SP_SERVICE_ID").toString()));
spStatOther.setCallNum(Long.valueOf(data.get("CALL_NUM").toString()));
spStatOther.setDealDate(new Date());
spStatOtherMapper.insertSelective(spStatOther);
/*}
i++;*/
}
}
logger.info("[汇总] 数据汇总成功");
return true;
}catch(Exception e){
e.printStackTrace();
logger.info("[汇总] 数据汇总失败" );
throw new RuntimeException("运行时出错！");
}
}
4、如下是spring配置事物要注意的
注意的几点:
1 @Transactional 只能被应用到public方法上, 对于其它非public的方法,若是标记了@Transactional也不会报错,但方法没有事务功能.
2用 spring 事务管理器,由spring来负责数据库的打开,提交,回滚.默认遇到运行期例外(throw new RuntimeException("注释");)会回滚，即遇到不受检查（unchecked）的例外时回滚；而遇到须要捕获的例外(throw new Exception("注释");)不会回滚,即遇到受检查的例外（就是非运行时抛出的异常，编译器会检查到的异常叫受检查例外或说受检查异常）时，需咱们指定方式来让事务回滚要想全部异常都回滚,要加上 @Transactional( rollbackFor={Exception.class,其它异常}) .若是让unchecked例外不回滚： @Transactional(notRollbackFor=RunTimeException.class)
以下:
@Transactional(rollbackFor=Exception.class) //指定回滚,遇到异常Exception时回滚
public void methodName() {
throw new Exception("注释");
}
@Transactional(noRollbackFor=Exception.class)//指定不回滚,遇到运行期例外(throw new Runt
但愿对你们有帮助!
