Java_遍历获取json数据的所有key值

 1     public static void getJsonKey(Object obj,String listname){
 2         if(obj instanceof JSONObject){
 3             for (Map.Entry<String, Object> entry : ((JSONObject) obj).entrySet()) {
 4                 System.out.println(listname+":"+entry.getKey());
 5                 if(!(entry.getValue() instanceof String)){
 6                     getJsonKey(entry.getValue(),entry.getKey());
 7                 }
 8             }
 9         }
10         if(obj instanceof JSONArray){
11             JSONArray jsonArray = (JSONArray) obj;
12             for (int i = 0;i < jsonArray.size();i++){
13                 getJsonKey(jsonArray.get(i),listname);
14             }
15         }
16     }
