        Map page = new HashMap<>();
        page.put("page",pageNum.toString());

        R r = orderFeignService.listWithItem(page);
        System.out.println(JSON.toJSONString(r));
        model.addAttribute("orders",r);

        return "orderList";
    }
}

异步通知内网穿透环境搭建

有一个问题就是请求头不匹配

修改nginx配置文件：

支付完成回调：

首先验证签名：

@RestController
public class OrderPayedListener {

    @Autowired
    OrderService orderService;

    @Autowired
    AlipayTemplate alipayTemplate;

    @PostMapping("/payed/notify")
    public String handelAlipayed(PayAsyncVo vo,HttpServletRequest request) throws UnsupportedEncodingException, AlipayApiException {
        //只要我们收到了支付宝给我们异步的通知，告诉我们订单支付成功。返回success,支付宝不在通知
//        Map map = request.getParameterMap();
//        for (String key : map.keySet()) {
//            String value = request.getParameter(key);
//            System.out.println("参数名:" + key + "=>参数值：" + value);
//        }
        //验签
        Map params = new HashMap();
        Map requestParams = request.getParameterMap();
        for (Iterator iter = requestParams.keySet().iterator(); iter.hasNext(); ) {
            String name = (String) iter.next();
            String[] values = (String[]) requestParams.get(name);
            String valueStr = "";
            for (int i = 0; i < values.length; i++) {
                valueStr = (i == values.length - 1) ? valueStr + values[i]
                        : valueStr + values[i] + ",";
            }
            //乱码解决，这段代码在出现乱码时使用
//            valueStr = new String(valueStr.getBytes("ISO-8859-1"), "utf-8");
            params.put(name, valueStr);
        }

        //调用SDK验证签名
        boolean signVerified = AlipaySignature.rsaCheckV1(params, alipayTemplate.getAlipay_public_key(), alipayTemplate.getCharset(), alipayTemplate.getSign_type());
        if (signVerified) {
            //签名验证成功
            System.out.println("签名验证成功...");
            String result = orderService.handlePayResult(vo);
            return result;
        } else {
            System.out.println("签名验证失败...");
            return "error";
        }
    }
}

然后处理支付结果：

 @Override
    public String handlePayResult(PayAsyncVo vo) {
        //1、保存交易流水
        PaymentInfoEntity infoEntity = new PaymentInfoEntity();
        infoEntity.setAlipayTradeNo(vo.getTrade_no());
        infoEntity.setOrderSn(vo.getOut_trade_no());
        infoEntity.setPaymentStatus(vo.getTrade_status());
        infoEntity.setCallbackTime(vo.getNotify_time());

        paymentInfoService.save(infoEntity);

        //2、修改订单的状态信息
        if(vo.getTrade_status().equals("TRADE_SUCCESS") || vo.getTrade_status().equals("TRADE_FINISHED")){
            //支付成功状态
            String outTradeNo = vo.getOut_trade_no();
            this.baseMapper.updateOrderStatus(outTradeNo,OrderStatusEnum.PAYED.getCode());
        }
        return "success";
    }
