java 配置事务回滚 java添加事务回滚

Java事务回滚需要添加

TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();

serviceImplement完整代码如下：

//删除用户
@Transactional(rollbackFor=Exception.class)
public boolean deleteUser(String userIds) {
 int failflag = 0;
 if(!Constant.isEmpty(userIds)) {
	String[] userId = userIds.split(",");
	if(userId.length!=0) {
		for(int i=0;i<userId.length;i++) {
			if(!userDao.deleteUser(Integer.valueOf(userId[i]))) {
				failflag = failflag +1;
			}
		}
	}
}
  if(failflag==0) {
	return true;
	}else {
		//数据回滚
		TransactionAspectSupport.currentTransactionStatus().setRollbackOnly(); 
		return false;
	}
}
