主动查询付款结果

封装查询支付结果的WEB方法

编写ZfbController.java代码

@Login
@PostMapping("/updateOrderStatus")
@ApiOperation("更新商品订单状态")
public R updateOrderStatus(@RequestBody UpdateOrderStatusForm form, @RequestHeader HashMap header) {
    ValidatorUtils.validateEntity(form);
    String token = header.get("token").toString();
    int userId = Integer.parseInt(jwtUtils.getClaimByToken(token).getSubject());
    int orderId = form.getOrderId();
    OrderEntity orderEntity = new OrderEntity();
    orderEntity.setUserId(userId);
    orderEntity.setId(orderId);
    QueryWrapper wrapper = new QueryWrapper(orderEntity);
    int count = orderService.count(wrapper);
    if (count == 0) {
        return R.error("用户与订单不匹配");
    }
    orderEntity = orderService.getOne(wrapper);
    String code = orderEntity.getCode();

    try {
        AlipayClient client = new DefaultAlipayClient(
            gateway,
            microApp_appId,
            microApp_privateKey,
            "json",
            "UTF-8",
            microApp_publicKey,
            "RSA2"
        );
        AlipayTradeQueryRequest request = new AlipayTradeQueryRequest();
        request.setBizContent("{" +
                "\"out_trade_no\":\"" + code + "\"," +
                "\"query_options\":[" +
                "\"TRADE_SETTLE_INFO\"" +
                "]" +
                " }");
        AlipayTradeQueryResponse response = client.execute(request);
        if (response.isSuccess()) {
            String tradeStatus = response.getTradeStatus();
            if ("TRADE_SUCCESS".equals(tradeStatus) || "TRADE_FINISHED".equals(tradeStatus)) {
                UpdateWrapper updateWrapper = new UpdateWrapper();
                updateWrapper.eq("code", code);
                updateWrapper.set("status", 2);
                updateWrapper.set("payment_type", 2);
                updateWrapper.set("prepay_id", response.getTradeNo());
                orderService.update(updateWrapper);
                return R.ok("订单状态已修改");
            } else {
                return R.ok("订单状态未修改");
            }
        }
        return R.ok("订单状态未修改");
    } catch (Exception e) {
        e.printStackTrace();
        return R.error("查询支付订单失败");
    }
}

发起页面刷新请求

编写OrderActivity.java代码

@Override
protected void onResume() {
    super.onResume();
    OrderActivity.this.runOnUiThread(new Runnable() {
        @Override
        public void run() {
            orderView.loadUrl("file:///android_asset/order.html");
        }
    });
}
