 @ApiOperation("生成订单信息")
    @RequestMapping(value = "/saveOrder")
    @ResponseBody
    @Transactional
    public ApiResult<Long> saveOrder(@Valid @RequestBody OrderRequest request) 

        PaymentOrder order = new PaymentOrder();
        order.setAccountId(request.getAccountId());
        order.setTeamId(request.getTeamId());
        order.setTotalAmount(request.getTotalAmount());
        order.setPayType(0);
        order.setDescription(request.getDescription());
        order.setOrderType(request.getOrderType());
        order.setCompany(request.getCompany());
        order.setRemarks(request.getRemarks());
        order.setPayStatus(PaymentStatusEnum.NOT_PAID.getType());
        order.setCreateTime(LocalDateTime.now());

        Long id = paymentOrderService.saveOrder(order);

        List<OrderProductRequest> orderProductRequestList = request.getOrderProductList();
        if (orderProductRequestList == null) 
            throw new PaymentException(ResponseContants.NOT_EXISTS, ResponseContants.NOT_EXIST_MSG);
        

        Boolean b = paymentOrderService.checkMoney(orderProductRequestList, request.getTotalAmount());

        List<PaymentOrderProduct> orderProductList = new ArrayList<>();
        for (OrderProductRequest orderProductRequest : orderProductRequestList) 
            PaymentOrderProduct orderProduct = new PaymentOrderProduct();
            BeanUtil.copyProperties(orderProductRequest, orderProduct);
            orderProduct.setOrderId(id);
            orderProductList.add(orderProduct);
        
        paymentOrderProductService.saveOrderProductList(orderProductList);

        //获得支付方式
//        Integer payType = request.getPayType();
//        switch (payType) 
//            case 1:
//                //微信
//
//                break;
//            case 2:
//                //支付宝
//                String s = paymentOrderService.aliPayPage(id);
//                System.out.println(s);
//                break;

            return ApiResult.resultIsEmpty();
        
        OrderVo vo = new OrderVo();
        BeanUtil.copyProperties(order, vo);
        List<PaymentOrderProduct> orderProductList = paymentOrderProductService.getOrderProductList(query.getId());
        List<OrderProductVo> orderProductVoList = new ArrayList<>();
        for (PaymentOrderProduct orderProduct : orderProductList) 
            OrderProductVo orderProductVo = new OrderProductVo();
            BeanUtil.copyProperties(orderProduct, orderProductVo);

            //具体的商品类
            Object obj = paymentOrderProductService.getProductObject(orderProductVo.getProductType(), orderProductVo.getProductId());
            orderProductVo.setProductObject(obj);

            orderProductVoList.add(orderProductVo);

                //具体的商品类
                Object obj = paymentOrderProductService.getProductObject(orderProductVo.getProductType(), orderProductVo.getProductId());
                orderProductVo.setProductObject(obj);

                orderProductVoList.add(orderProductVo);
            
            vo.setOrderProductList(orderProductVoList);

            Map<String, String> outMap = new TreeMap<String, String>();

            if (signVerified) 
                // TODO 验签成功后，按照支付结果异步通知中的描述，对支付结果中的业务内容进行二次校验，校验成功后在response中返回success并继续商户自身业务处理，校验失败返回failure

                //商户订单号
                String outTradeNo = request.getParameter("out_trade_no");

                    outMap.put("return_msg", "OK");
                    //当商户收到服务器异步通知并打印出 success 时，服务器异步通知参数 notify_id 才会失效
                    response.getWriter().print("success");
                    System.out.println("success");
                    log.info("支付宝支付成功！out_trade_no:" + outTradeNo + ", trade_status:" + trade_status);
                 else 
                    outMap.put("trade_status", trade_status);
                    log.error("支付宝支付通信失败！" + trade_status);

                outMap.put("return_code", "FAILURE");
                outMap.put("return_msg", "验签失败");
                log.error("验签失败");
            

            String respMessage = null;

            respMessage = XMLUtil.mapToXml(outMap);
            PrintWriter out = response.getWriter();
            out.print(respMessage);
            out.flush();

            e.printStackTrace();

10. 微信支付输出二维码图片

 @RequestMapping(value = "/wePayQR")
    @ResponseBody
    public ApiResult<Boolean> wePayQR(@RequestBody @Valid OrderByIdQuery query, HttpServletResponse response) throws IOException 
        String codeUrl = paymentOrderService.wePayUrl(query.getId());

        response.setContentType("image/jpeg;charset=UTF-8");
        response.setHeader("Pragma", "No-cache");
