如果是尋求解決問題的，可以劃走了，我這篇帖子是詢問問題的哈哈哈，實在抱歉，搞了很久沒搞定，如果你是大牛 幫我看看

項目用的是SpringCloud SpringCloud alibaba + mybatis plus+druid+shardingjdbc+seata
在做分布式事務事出現的問題，每個服務對應自己的數據庫，也做了分庫
比如user表，以userId分庫，如果不用shardingjdbc分庫，seata可以正常使用，如果加上shardingjdbc分庫，則報錯如下：

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.

在網上查了很久，依舊沒有找到解決方案，大部分說是由于user表沒有主鍵，或者是用了聯合主鍵，或者是主鍵沒有自增，或者是使用的mybatis plus自帶的插入方法，sql中不帶主鍵字段，都嘗試過了，依舊是這個問題

下面是代碼：

    @Override
    @Transactional(rollbackFor = ArithmeticException.class)
    @ShardingTransactionType(TransactionType.BASE)
    public ReturnResponse<LoginRespDTO> smsLogin(LoginReqDTO reqDTO) {
        log.info("【 驗證碼登錄入參 】{}", JSON.toJSON(reqDTO));
        LoginRespDTO resp = new LoginRespDTO();
        try {
            // 發送驗證碼后會將驗證碼存入redis, 5分鐘有效, 在登錄的時候要從redis取, 如果取時異常, rpc短信服務去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 -> 驗證碼校驗失敗 】{}", 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) {
            // 首次注冊, 送積分
            ReturnResponse<AccountRespDTO> account = accountClient.createAccount(accountReqDTO);
            if (!account.isSuccess()) {
                log.error("【 smsLogin -> 用戶注冊失敗 】{}", JSON.toJSON(account));
                return ReturnResponse.fail(RtnConstant.REGISTER_FAIL_CODE, RtnConstant.REGISTER_FAIL_MSG);
            }
           // 注冊返現邏輯省略...
            log.info("【 注冊成功... 】");
        } else {
            userId = user.getUserId();
        }
        // 生成token
        String token = this.tokenService.createToken(userId);
        resp.setToken(token);
        resp.setLoginResult(true);
        UserContext.addRtnResultMap(resp);
        log.info("【 登錄成功.. 】");
        return ReturnResponse.success(resp);
    }

也寫了aop把事務模式設置為BASE，當feign調用account服務創建賬戶時，插入分庫的user表就會報最開始的異常。表有主鍵沒有問題，不知道有了解的大神幫忙解決下不
