          data:{
            dataDetail: JSON.stringify(data)
          }

          alert('post code done')
          this.$router.push({path:'/pay'})

    @RequestMapping(value="PlaceOrder.do",produces="application/json;charset=utf-8")
    @ResponseBody
    public String PlaceOrder(@RequestBody Map<String,String> params, HttpServletRequest request,HttpServletResponse response,
            SdOrder sdOrder,String orderStartPoint)/* throws UnsupportedEncodingException*/{
        //前端接收到的json串
        /*dataDetail : [{"receiveAdd":"北京市通州区番茄俱乐部","sendAdd":"北京市通州区恺王国际","distance":9.463,
                "goodsName":"生活用品","editname":"11","weight":"&lt;=5kg","editnotename":"11",

            System.out.println("总共获取到："+params.size()+"个参数");
            for(String key : params.keySet()){
                System.out.println(key + " : " + params.get(key));
            }
