自定义异常回滚@Transactional注解

Posted 2023-03-19 迷糊桃

//重点关注的是@Transactional注解和TransactionAspectSupport.currentTransactionStatus().setRollbackOnly()@Override
    @Transactional(rollbackFor = RuntimeException.class)
    public ServerResp<Object> updateDistributionRule(UpdateDistributionRuleRequest req) 
        ServerResp<Object> resp = new ServerResp<>();
        try 
            JSONArray jsonArray = JSONArray.parseArray(req.getDistributionList());
            if (null == jsonArray )
                return resp.error("分配数组为空");
            
            List<TfCustomerDistributeRole> list = JSON.parseArray(jsonArray.toJSONString(), TfCustomerDistributeRole.class);
            for (TfCustomerDistributeRole distributeRole : list)
                Integer distributeCount = tfCustomerDistributeRoleMapper.updateDistributeByStoreIdAndclerkId(distributeRole);
                if (distributeCount == 0)
                    throw new RuntimeException("修改店员分配规则错误，回滚");
                
            
            return resp.success("修改成功");
        catch (RuntimeException e) 
            //触发强制回滚
            e.printStackTrace();
            logger.log(MyLogUtil.LOG_ERROR, "触发回滚,入参：" + req + ",错误类型" ,e);
            TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
            return resp.error("修改店员分配规则出现错误");
        catch (Exception e)
            e.printStackTrace();
            logger.log(MyLogUtil.LOG_ERROR,"修改分配规则错误");
            return resp.error("分配规则修改错误");
        
    

@Override
    @Transactional()
    public boolean sendTfProductPublicity(Map params) 

　　 // 启用一个事务
    Object obj = TransactionAspectSupport.currentTransactionStatus().createSavepoint();

 　 代码···················

   // 报错后 对上面创建的事务进行回滚
   TransactionAspectSupport.currentTransactionStatus().rollbackToSavepoint(obj);
