Integrate wechat payment

80 Line error null pointer exception

Failure is always displayed here
When integrating wechat payment today, I encountered a bug, When updating the order status, we need to query the corresponding order according to the order number and change the order status to paid

The certificate is not found orderinfo And then we found out getid It doesn't work. It should getOrderid

Restart the project after the change
And then we found out
Now the appointment is successful

So why did we change here and pay successfully , No need to pay again is this .

1. Front-end call interface , Generate qr code , Return to one map

map The most important one is url Store QR code

2. Front end analysis map, Display QR code , At the same time, each 3 Check the payment status in seconds

3. Query payment status , Change the payment status of the project database when the payment is successful

4. Return the updated results to the front end , Automatically jump to the details page

// Update order status 
@Override
public void paySuccess(String tradeNo, Map<String, String> resultMap) {
    
    //1. Get the payment record according to the order number 
    QueryWrapper<PaymentInfo> queryWrapper = new QueryWrapper<>();
    queryWrapper.eq("out_trade_no", tradeNo);
    queryWrapper.eq("payment_type", PaymentTypeEnum.WEIXIN.getStatus());
    PaymentInfo paymentInfo = baseMapper.selectOne(queryWrapper);

    //2. Update payment information 
    paymentInfo.setPaymentStatus(PaymentStatusEnum.PAID.getStatus());
    paymentInfo.setCallbackTime(new Date());
    paymentInfo.setTradeNo(resultMap.get("transaction_id"));
    paymentInfo.setCallbackContent(resultMap.toString());
    baseMapper.updateById(paymentInfo);

    //3. Get the order information according to the order number 
    log.info(String.valueOf(paymentInfo.getOrderId()));
    OrderInfo orderInfo = orderService.getById(paymentInfo.getOrderId());
    orderInfo.setOrderStatus(OrderStatusEnum.PAID.getStatus());

    //4. Update order information 
    orderService.updateById(orderInfo);

    //5. Call the hospital interface , Update payment information 
    hospApi(orderInfo);

}

private void hospApi(OrderInfo orderInfo) {
    
    SignInfoVo signInfoVo = hospitalFeignClient.getSignInfoVo(orderInfo.getHoscode());
    if (null == signInfoVo) {
    
        throw new YyghException(ResultCodeEnum.PARAM_ERROR);
    }
    Map<String, Object> reqMap = new HashMap<>();
    reqMap.put("hoscode", orderInfo.getHoscode());
    reqMap.put("hosRecordId", orderInfo.getHosRecordId());
    reqMap.put("timestamp", HttpRequestHelper.getTimestamp());
    String sign = HttpRequestHelper.getSign(reqMap, signInfoVo.getSignKey());
    reqMap.put("sign", sign);
    JSONObject result = HttpRequestHelper.sendRequest(reqMap, signInfoVo.getApiUrl() + "/order/updatePayStatus");
    if (result.getInteger("code") != 200) {
    
        throw new YyghException(result.getString("message"), ResultCodeEnum.FAIL.getCode());
    }
}

And we just got stuck in the first 4 Step when we finish modifying the code, the front end checks that we have updated , Previous payment operations have not been affected

Wechat refund

When writing the refund interface today, there is a bug The money is refunded, but the front end still shows that you have made an appointment ,

Through investigation, we found this Boolean There is a problem , Whether there is an error or not, it is returned false
