json格式的字符串解析成Map对象

private static HashMap<String, String> toHashMap(Object object)  
   {  
       HashMap<String, String> data = new HashMap<String, String>();  
       // 将json字符串转换成jsonObject  
       JSONObject jsonObject = JSONObject.fromObject(object);  
       Iterator it = jsonObject.keys();  
       // 遍历jsonObject数据，添加到Map对象  
       while (it.hasNext())  
       {  
           String key = String.valueOf(it.next());  
           String value = (String) jsonObject.get(key);  
           data.put(key, value);  
       }  
       return data;  
   }
