事务是在service层中做的，代码段：
@Transactional(readOnly=false,propagation=Propagation.REQUIRED,rollbackFor=Exception.class)
public String test(String openid,int account)throws Exception{
String flag = "0";
int f = 0;
f = memberDao.updateUserAccount(openid, account);
memberDao.updateSubscribe(openid, 1);
//抛异常
if(f==0){
throw new Exception("测试异常");
}
return flag;
}
test()方法中的两个调用dao层的动作，第一个是正常的，第二个是有意弄错的，但是执行的时候并没有回滚。
请各位路过的大神帮忙卡看！！！
