json数据封装

1、java

import org.json.JSONArray;
import org.json.JSONObject;


public class Anotion 
{
public static void main(String args[])
{
 JSONObject children2 = new JSONObject();  
 children2.put("id", "2");  
 children2.put("text", "子节点2");

     JSONObject children1 = new JSONObject();  
     children1.put("id", "1");  
     children1.put("text", "子节点1"); 
       
     JSONArray json_e = new JSONArray();
     json_e.put(children1); 
     json_e.put(children2); 
     
     JSONObject jsonObject = new  JSONObject();
     jsonObject.put("id", "0");
     jsonObject.put("text", "根节点");
     jsonObject.put("children", json_e);
     System.out.println("["+jsonObject.toString()+"]");
      
}
}

2、显示

[{"id":"0","text":"根节点","children":[{"id":"1","text":"子节点1"},{"id":"2","text":"子节点2"}]}]
