篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了shardingjdbc+mybatisP+Seata 报错 throw new ShouldNeverHappenException，Failed to fetch schema of t_user相关的知识，希望对你有一定的参考价值。
如果是寻求解决问题的，可以划走了，我这篇帖子是询问问题的哈哈哈，实在抱歉，搞了很久没搞定，如果你是大牛 帮我看看
项目用的是SpringCloud SpringCloud alibaba + mybatis plus+druid+shardingjdbc+seata
在做分布式事务事出现的问题，每个服务对应自己的数据库，也做了分库
比如user表，以userId分库，如果不用shardingjdbc分库，seata可以正常使用，如果加上shardingjdbc分库，则报错如下：
org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.executor.ExecutorException: Error preparing statement. Cause: io.seata.common.exception.ShouldNeverHappenException: [xid:192.168.201.159:8091:8494064366571848511]get table meta failed, please check whether the table `t_user` exists.

在网上查了很久，依旧没有找到解决方案，大部分说是由于user表没有主键，或者是用了联合主键，或者是主键没有自增，或者是使用的mybatis plus自带的插入方法，sql中不带主键字段，都尝试过了，依旧是这个问题
下面是代码：
@Override
@Transactional(rollbackFor = ArithmeticException.class)
@ShardingTransactionType(TransactionType.BASE)
public ReturnResponse<LoginRespDTO> smsLogin(LoginReqDTO reqDTO)
log.info("【 验证码登录入参 】", JSON.toJSON(reqDTO));
LoginRespDTO resp = new LoginRespDTO();
try
// 发送验证码后会将验证码存入redis, 5分钟有效, 在登录的时候要从redis取, 如果取时异常, rpc短信服务去mysql查
code = RedisUtil.get(CommonConstants.CAPTCHA_REDIS_PREFIX + reqDTO.getPhone() + 3);
catch (Exception e)
ReturnResponse<SmsSendRecordDTO> sendRecord = smsClient.findSendRecord(reqDTO.getPhone());
// .....
if (this.checkVerifyCode(code, resp, reqDTO.getSmsCode()))
log.error("【 smsLogin -> 验证码校验失败 】", JSON.toJSON(resp));
return ReturnResponse.fail(resp);
AccountReqDTO accountReqDTO = new AccountReqDTO();
this.buildAccountReqDTO(accountReqDTO, reqDTO);
ReturnResponse<AccountRespDTO> accountByPhone = accountClient.findAccountByPhone(accountReqDTO);
AccountRespDTO user = accountByPhone.getData();
long userId = -1L;
if (user == null)
// 首次注册, 送积分
ReturnResponse<AccountRespDTO> account = accountClient.createAccount(accountReqDTO);
if (!account.isSuccess())
log.error("【 smsLogin -> 用户注册失败 】", JSON.toJSON(account));
return ReturnResponse.fail(RtnConstant.REGISTER_FAIL_CODE, RtnConstant.REGISTER_FAIL_MSG);
// 注册返现逻辑省略...
log.info("【 注册成功... 】");
else
userId = user.getUserId();
// 生成token
String token = this.tokenService.createToken(userId);
resp.setToken(token);
resp.setLoginResult(true);
UserContext.addRtnResultMap(resp);
log.info("【 登录成功.. 】");
return ReturnResponse.success(resp);
也写了aop把事务模式设置为BASE，当feign调用account服务创建账户时，插入分库的user表就会报最开始的异常。表有主键没有问题，不知道有了解的大神帮忙解决下不
以上是关于shardingjdbc+mybatisP+Seata 报错 throw new ShouldNeverHappenException，Failed to fetch schema of t_user的主要内容，如果未能解决你的问题，请参考以下文章
