JSONObject json = JSONObject.parseObject(content);

Gson gson = new Gson();

        map = gson.fromJson(jsonString, map.getClass());#關鍵
        String goodsid=(String) map.get("goods_id");
        System.out.println("map的值為:"+goodsid);      

XcxMessageVo xcxVo = gson.fromJson(content,XcxMessageVo.class);

        Object obj = null;
        String path = getRequest().getSession().getServletContext().getRealPath("") + "/clt2/" + filePath + "/index.htm";

        }

        if (obj == null) {
            return "";
        }
        return (String) obj;
    }
