2、接收並解析

 @RequestMapping(value = "/torderList")
    @ResponseBody
    public String torderList(HttpServletRequest request) throws IOException {
    String orderReq = HttpClientUtil.receivePost(request.getInputStream());
    OrderReq req = JSONObject.parseObject(orderReq, OrderReq.class)；
        return “ ”;
    }
