無法解析並從json獲取數組結果

我知道如何解析json並從java中獲得json數組的結果，但是我有一個json，我無法找出哪個是數組，以及如何實現我解析它，在這個json中，我想'state'和'base_url'。可以有人幫助我，我該如何做到這一點。無法解析並從json獲取數組結果

{ 
    "tree": [{ 
     "data": { 
      "title": "/clusterstate.json", 
      "attr": { 
       "href": "zookeeper?detail=true&path=%2Fclusterstate.json" 
      } 
     } 
    }], 
    "znode": {

    } 
}

這是我的代碼，讓我知道我在哪裏解析

URL url = new URL("http://myipaddress:8080/solr/zookeeper? detail=true&path=%2Fclusterstate.json"); 

    System.out.println(url); 

    java.net.URLConnection connection = url.openConnection(); 
    //String ref = "http://ajax.googleapis.com"; 
    //connection.addRequestProperty("Referer", ref); 

    String line; 
    StringBuilder builder = new StringBuilder(); 
    BufferedReader reader = new BufferedReader(new InputStreamReader(
      connection.getInputStream())); 
    while ((line = reader.readLine()) != null) { 
     builder.append(line); 
    } 

    JSONObject json = new JSONObject(builder.toString()); 


    //System.out.println(json); 
    JSONArray entries = json.getJSONArray("tree"); 
    for (int i = 0; i < entries.length(); i++) { 
     JSONObject row = entries.getJSONObject(i); 

     bean test = new bean(); 
     test.setRss(row.getString("data")); 
     System.out.println(row.getString("data")); 

    } 
    } 
    catch (Exception e) { 
     // TODO: handle exception 
    } 

    return "cloud"; 
}

你試過用** json.parse（jsonresponse）**; –

不，我會盡力讓你知道，謝謝你的快速回復 – user3291784

爲什麼指針/ znode/data中的值是序列化的JSON對象而不是對象本身？ – fge

JSONObject znode = json.getJSONObject("znode"); 
String data = znode.getJSONObject("data"); 
JSONObject dataJson = new JSONObject(data);

從那裏，你對你自己 - 它看起來像cmn2 - >碎片-shard1 - >狀態等，但是閱讀這種形式的JSON有點困難。我建議記錄dataJson，以便更清楚地看到它。
