//微信支付创建订单
    @PostMapping("/createOrder")
    public R createOrder(@RequestBody PayOrder payOrder) throws WxPayException, ParseException {
        //支付方式微信
        payOrder.setType(0);
        //随机订单号
        String number = YitIdHelper.nextId()+"";
        payOrder.setId(Long.valueOf(number));
        //系统当前时间
        payOrder.setCreateTime(new Date());
        //支付状态
        payOrder.setState(0);
        //订单创建
        payOrderMapper.insert(payOrder);
        WxPayUnifiedOrderRequest request = new WxPayUnifiedOrderRequest();
        request.setVersion("1.0");
        request.setDeviceInfo("WEB");
        request.setBody("支付");
        request.setNotifyUrl(servlet + "/payBack/wxPay");//回调地址
        request.setTradeType("NATIVE");
        request.setProductId(number);
        request.setOutTradeNo(number);
        request.setFeeType("CNY");
        //金额需*100
        request.setTotalFee(payOrder.getAmount().multiply(BigDecimal.valueOf(100)).intValue());
        request.setSpbillCreateIp("127.0.0.1");
        //调用生成二维码
        WxPayNativeOrderResult wxPayNativeOrderResult = wxService.createOrder(request);
        String codeUrl = wxPayNativeOrderResult.getCodeUrl();
        Map wxReturn = new HashMap<>();
        wxReturn.put("codeUrl",codeUrl);
        wxReturn.put("outTradeNo",number);
        return data(wxReturn);
    }

代码如下（示例）：

    //微信支付回调
    @RequestMapping("/wxPay")
    public String mp(@RequestBody String data) {
        WxPayOrderNotifyResult result = WxPayOrderNotifyResult.fromXML(data);
        String orderId = result.getOutTradeNo();
        return process2(orderId, result.getTransactionId(), result.getOpenid());
    }
    private String process2(String payOrderId, String orderNo, String openid)
    {

        PayOrder payOrder = payOrderMapper.selectById(payOrderId);
        if (payOrder == null) {
            System.out.println("订单不存在");
            return "SUCCESS";
        }
        //成功后业务处理省略
        ········
        payOrder.setState(1);
        payOrderMapper.updateByPrimaryKey(payOrder);
        if (payOrder.getState() == 1) {
            System.out.println("订单已完成");
            return "SUCCESS";
        }
        return "SUCCESS";
    }
