  @Override
    public void setTingLogisticsNumber(SetTingLogisticsNumberReq request, SetTingLogisticsNumberResp response) {

        int success = 0;
        int failure = 0;
        if (request.expressId == 1) {
            String regex = "(^[A-Z]{2}[0-9]{9}[A-Z]{2}$)";
            boolean flag = Pattern.matches(regex, request.startNo);
            if (flag) {
                Long ref = tradeMapper.selectExpressShipNo(request.startNo);
                if (ref == 0) {
                    List<String> expressShipNoList = CreateEMS(request.startNo, request.tradeIdList.size());
                    for (int i = 0; i < expressShipNoList.size(); i++) {
                        String expressShipNo = expressShipNoList.get(i);
                        String tradeId = request.getTradeIdList().get(i);
                        try {
                            tradeMapper.setTingLogisticsNumber(expressShipNo, Long.parseLong(tradeId));
                            success++;
                        } catch (NumberFormatException e) {
                            LOG.error(e);
                            failure++;
                        }
                    }
                    response.errorCode = success;
                    response.errorMessage = "设置成功" + success + "条," + "失败" + failure + "条";
                } else {
                    response.errorCode = 0;
                    response.errorMessage = "快递单号已存在!请重新输入";
                }
            } else {
                response.errorCode = 0;
                response.errorMessage = "格式不正确!请重新输入";
            }

        }
