简单json语句转化为map保存

主要用到了 net.sf.json.JSONObject类

需要用到的jar包 : jar包下载地址

 package test;

 import java.io.BufferedReader;

 import java.io.InputStream;

 import java.io.InputStreamReader;

 import java.net.HttpURLConnection;

 import java.net.URL;

 import java.util.HashMap;

 import java.util.Iterator;

 import java.util.List;

 import java.util.Map;

 import java.util.Map.Entry;  

 import net.sf.json.JSONObject;

 public class Test {

     private static HashMap<String, String> toHashMap(Object object){

         HashMap<String, String> data = new HashMap<String, String>();

         JSONObject jsonObject = JSONObject.fromObject(object);

         Iterator it = jsonObject.keys();

         while(it.hasNext()){

             String key = String.valueOf(it.next());

             String value = (String)jsonObject.get(key);

             data.put(key, value);

         }

         return data;

     }

     public static void main(String[] args) {  

        String jsonString = "{\"name\":\"admin\",\"retries\":\"3fff\",\"testname\" :\"ddd\",\"testretries\":\"fffffffff\"} ";

        HashMap<String, String> mp = toHashMap(jsonString);

        System.out.println(mp.get("name"));

        System.out.println(mp.get("retries"));

        System.out.println(mp.get("testname"));

     }

 }
