將json格式的字符串解析成Map對(duì)象

1. /** 

2.     * 將json格式的字符串解析成Map對(duì)象 <li> 

3.     * json格式：{"name":"admin","retries":"3fff","testname" 

4.     * :"ddd","testretries":"fffffffff"} 

5.     */  

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

7.    {  

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

9.        // 將json字符串轉(zhuǎn)換成jsonObject  

10.        JSONObject jsonObject = JSONObject.fromObject(object);  

11.        Iterator it = jsonObject.keys();  

12.        // 遍歷jsonObject數(shù)據(jù)，添加到Map對(duì)象  

13.        while (it.hasNext())  

14.        {  

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

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

17.            data.put(key, value);  

18.        }  

19.        return data;  

20.    }  

21.  把List轉(zhuǎn)換成JSON數(shù)據(jù)：

22. 
    

23. List<UserInfo> list = new ArrayList<UserInfo>();

24. UserInfo user = new UserInfo(1001, "張三");

25. list.add(user);

26. list.add(user);

27. list.add(user);

28. JSONArray jsonArray = JSONArray.fromObject(list);

29. System.out.println(jsonArray);

30. 

把Map轉(zhuǎn)換成json， 要使用jsonObject對(duì)象：

Map<String, Object> map = new HashMap<String, Object>();

map.put("userId", 1001);

map.put("userName", "張三");

map.put("userSex", "男");

JSONObject jsonObject = JSONObject.fromObject(map);

System.out.println(jsonObject);

對(duì)象轉(zhuǎn)換成JSON：

UserInfo user = new UserInfo(1001,"張三");

JSONArray jsonArray = JSONArray.fromObject(user);  

System.out.println( jsonArray )

;  

將數(shù)組轉(zhuǎn)換為JSON：

String[] arr = {"asd","dfgd","asd","234"};

JSONArray jsonarray = JSONArray.fromObject(arr);

System.out.println(jsonarray);
