blic void saveErrorNwInfo(Map<String, Object>  map,String type){
    JSONObject mapobj = new JSONObject();
    JSONObject obj = new JSONObject();
    try {
        //map转json字符串
        String s = new Gson().toJson(map);
        //字符串转jsonobject
        obj = JSON.parseObject(s);
        //map 直接转jsonObject
        mapobj.putAll(map);
        Log.info("s"+s);
        Log.info("obj"+obj);
        Log.info("mapobj"+mapobj);
    }catch (Exception e){
        e.printStackTrace();
    }
