java判断JSON字符串是JSONObject或JSONArray


import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
String xssJson = "{\"name\":\"\",\"age\":\"\"}";
        Object object = JSON.parse(json);
        if (object instanceof JSONObject) {
            JSONObject jsonObject = (JSONObject) object;
            log.info(" jsonObject:" + jsonObject.toJSONString());
        } else if (object instanceof JSONArray) {
            JSONArray jsonArray = (JSONArray) object;
            log.info(" jsonArray:" + jsonArray.toJSONString());
        }
