扫描二维码支付

js调用

//生成支付二维码pay() {this.dialogPayVisible = true;weixinApi.createNative(this.orderId).then((response) => {this.payObj = response.data;if (this.payObj.codeUrl == "") {this.dialogPayVisible = false;this.$message.error("支付错误");} else {this.timer = setInterval(() => {this.queryPayStatus(this.orderId);}, 3000);}});},//查询支付状态queryPayStatus(orderId) {weixinApi.queryPayStatus(orderId).then((response) => {if (response.message == "支付中") {return;}clearInterval(this.timer);window.location.reload();});},

这里需要注意的是，生成二维码后，添加一个定时器，查询支付状态

查询支付状态

@ApiOperation(value = "查询支付状态")@GetMapping("/queryPayStatus/{orderId}")public Result queryPayStatus(@ApiParam(name = "orderId", value = "订单id", required = true)@PathVariable("orderId") Long orderId) {//调用查询接口Map resultMap = weixinPayService.queryPayStatus(orderId, PaymentTypeEnum.WEIXIN.name());if (resultMap == null) {//出错return Result.fail().message("支付出错");}if ("SUCCESS".equals(resultMap.get("trade_state"))) {//如果成功//更改订单状态，处理支付结果String out_trade_no = resultMap.get("out_trade_no");paymentService.paySuccess(out_trade_no, PaymentTypeEnum.WEIXIN.getStatus(), resultMap);return Result.ok().message("支付成功");}return Result.ok().message("支付中");}

Service 实现

/*** 支付成功*/@Overridepublic void paySuccess(String outTradeNo, Integer paymentType, Map paramMap) {PaymentInfo paymentInfo = this.getPaymentInfo(outTradeNo, paymentType);if (null == paymentInfo) {throw new HospitalException(ResultCodeEnum.PARAM_ERROR);}if (!Objects.equals(paymentInfo.getPaymentStatus(), PaymentStatusEnum.UNPAID.getStatus())) {return;}//修改支付状态PaymentInfo paymentInfoUpd = new PaymentInfo();paymentInfoUpd.setPaymentStatus(PaymentStatusEnum.PAID.getStatus());paymentInfoUpd.setTradeNo(paramMap.get("transaction_id"));paymentInfoUpd.setCallbackTime(new Date());paymentInfoUpd.setCallbackContent(paramMap.toString());this.updatePaymentInfo(outTradeNo, paymentInfoUpd);//修改订单状态OrderInfo orderInfo = orderService.getById(paymentInfo.getOrderId());orderInfo.setOrderStatus(OrderStatusEnum.PAID.getStatus());orderService.updateById(orderInfo);// 调用医院接口，通知更新支付状态SignInfoVo signInfoVo= hospFeignClient.getSignInfoVo(orderInfo.getHoscode());if (null == signInfoVo) {throw new HospitalException(ResultCodeEnum.PARAM_ERROR);}Map 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 HospitalException(result.getString("message"), ResultCodeEnum.FAIL.getCode());}}/*** 获取支付记录*/private PaymentInfo getPaymentInfo(String outTradeNo, Integer paymentType) {QueryWrapper queryWrapper = new QueryWrapper<>();queryWrapper.eq("out_trade_no", outTradeNo);queryWrapper.eq("payment_type", paymentType);return baseMapper.selectOne(queryWrapper);}/*** 更改支付记录*/private void updatePaymentInfo(String outTradeNo, PaymentInfo paymentInfoUpd) {QueryWrapper queryWrapper = new QueryWrapper<>();queryWrapper.eq("out_trade_no", outTradeNo);baseMapper.update(paymentInfoUpd, queryWrapper);}

效果演示

点击支付后出现二维码

扫码后成功返回，不扫码会一直定时器调用支付状态查询接口，这块我其实感觉抛出错误的话，界面展示不是很人性化

取消预约

取消订单分两种情况：

1、未支付取消订单，直接通知医院更新取消预约状态

2、已支付取消订单，先退款给用户，然后通知医院更新取消预约状态

@ApiOperation(value = "取消预约")
@GetMapping("auth/cancelOrder/{orderId}")
public Result cancelOrder(@ApiParam(name = "orderId", value = "订单id", required = true)@PathVariable("orderId") Long orderId) {return Result.ok(orderService.cancelOrder(orderId));
}

service 实现

@Overridepublic Boolean cancelOrder(Long orderId) {OrderInfo orderInfo = this.getById(orderId);//1. 当前时间大于退号时间，不能取消预约DateTime quitTime = new DateTime(orderInfo.getQuitTime());if (quitTime.isBeforeNow()) {throw new HospitalException(ResultCodeEnum.CANCEL_ORDER_NO);}// 2.向医院系统发送取消预约的请求SignInfoVo signInfoVo = hospFeignClient.getSignInfoVo(orderInfo.getHoscode());if (null == signInfoVo) {throw new HospitalException(ResultCodeEnum.PARAM_ERROR);}Map 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/updateCancelStatus");if (result.getInteger("code") != 200) {throw new HospitalException(result.getString("message"), ResultCodeEnum.FAIL.getCode());} else {//3. 如果成功 判断是否支付 已经支付则退款if (orderInfo.getOrderStatus().intValue() == OrderStatusEnum.PAID.getStatus().intValue()) {//已支付 退款boolean isRefund = weixinService.refund(orderId);if (!isRefund) {throw new HospitalException(ResultCodeEnum.CANCEL_ORDER_FAIL);}}//4.更改订单状态orderInfo.setOrderStatus(OrderStatusEnum.CANCLE.getStatus());this.updateById(orderInfo);//5.发送mq信息更新预约数 我们与下单成功更新预约数使用相同的mq信息，不设置可预约数与剩余预约数，接收端可预约数加1即可OrderMqVo orderMqVo = new OrderMqVo();orderMqVo.setScheduleId(orderInfo.getScheduleId());//同时设置短信提示MsmVo msmVo = new MsmVo();msmVo.setPhone(orderInfo.getPatientPhone());msmVo.setTemplateCode("SMS_194640722");String reserveDate = new DateTime(orderInfo.getReserveDate()).toString("yyyy-MM-dd") + (orderInfo.getReserveTime() == 0 ? "上午" : "下午");Map param = new HashMap() {{put("title", orderInfo.getHosname() + "|" + orderInfo.getDepname() + "|" + orderInfo.getTitle());put("reserveDate", reserveDate);put("name", orderInfo.getPatientName());}};msmVo.setParam(param);orderMqVo.setMsmVo(msmVo);rabbitService.sendMessage(MqConst.EXCHANGE_DIRECT_ORDER, MqConst.ROUTING_ORDER, orderMqVo);}return true;}

这块的逻辑还是比较复杂的，主要看两个地方

• 微信退款的实现
• mq的整合

微信退款的实现

简单列一下实现方法，比较固定，和前面生成二维码接口类似

@Overridepublic Boolean refund(Long orderId) {try {PaymentInfo paymentInfoQuery = paymentService.getPaymentInfo(orderId, PaymentTypeEnum.WEIXIN.getStatus());RefundInfo refundInfo = refundInfoService.saveRefundInfo(paymentInfoQuery);if (refundInfo.getRefundStatus().intValue() == RefundStatusEnum.REFUND.getStatus().intValue()) {return true;}Map paramMap = new HashMap<>(8);paramMap.put("appid", ConstantPropertiesUtils.APPID);       //公众账号IDparamMap.put("mch_id", ConstantPropertiesUtils.PARTNER);   //商户编号paramMap.put("nonce_str", WXPayUtil.generateNonceStr());paramMap.put("transaction_id", paymentInfoQuery.getTradeNo()); //微信订单号paramMap.put("out_trade_no", paymentInfoQuery.getOutTradeNo()); //商户订单编号paramMap.put("out_refund_no", "tk" + paymentInfoQuery.getOutTradeNo()); //商户退款单号
//       paramMap.put("total_fee",paymentInfoQuery.getTotalAmount().multiply(new BigDecimal("100")).longValue()+"");
//       paramMap.put("refund_fee",paymentInfoQuery.getTotalAmount().multiply(new BigDecimal("100")).longValue()+"");paramMap.put("total_fee", "1");paramMap.put("refund_fee", "1");String paramXml = WXPayUtil.generateSignedXml(paramMap, ConstantPropertiesUtils.PARTNERKEY);HttpClient client = new HttpClient("https://api.mch.weixin.qq.com/secapi/pay/refund");client.setXmlParam(paramXml);client.setHttps(true);client.setCert(true);client.setCertPassword(ConstantPropertiesUtils.PARTNER);client.post();
//3、返回第三方的数据String xml = client.getContent();Map resultMap = WXPayUtil.xmlToMap(xml);if (null != resultMap && WXPayConstants.SUCCESS.equalsIgnoreCase(resultMap.get("result_code"))) {refundInfo.setCallbackTime(new Date());refundInfo.setTradeNo(resultMap.get("refund_id"));refundInfo.setRefundStatus(RefundStatusEnum.REFUND.getStatus());refundInfo.setCallbackContent(JSONObject.toJSONString(resultMap));refundInfoService.updateById(refundInfo);return true;}return false;} catch (Exception e) {e.printStackTrace();}return false;}

mq的整合

这块还是复用之前的方式，具体可以看我上一篇博客 尚医通-预约下单中rabbitmq的使用_周周写不完的代码的博客-CSDN博客

简单看一下订单生成和订单取消是如何复用一套逻辑的

先看订单生成

OrderMqVo orderMqVo = new OrderMqVo();
orderMqVo.setScheduleId(scheduleId);
orderMqVo.setReservedNumber(reservedNumber);
orderMqVo.setAvailableNumber(availableNumber);

对比下订单取消

OrderMqVo orderMqVo = new OrderMqVo();
orderMqVo.setScheduleId(orderInfo.getScheduleId());

看下 监听器

if (null != orderMqVo.getAvailableNumber()) {//下单成功更新预约数Schedule schedule = scheduleService.getScheduleId(orderMqVo.getScheduleId());schedule.setReservedNumber(orderMqVo.getReservedNumber());schedule.setAvailableNumber(orderMqVo.getAvailableNumber());scheduleService.update(schedule);
} else {//取消预约更新预约数Schedule schedule = scheduleService.getScheduleId(orderMqVo.getScheduleId());int availableNumber = schedule.getAvailableNumber().intValue() + 1;schedule.setAvailableNumber(availableNumber);scheduleService.update(schedule);
}

可以看到 订单取消不会设置 AvailableNumber，只设置了 id
