JSON学习（三）：Json与常见的类型之间的转换

List list=new ArrayList();
list.add("1");
list.add("2");
JsonArray json=JsonArray.fromObject(list)；

Map map = new HashMap();
map.put("欧尼", "json");
map.put("听我", Boolean.TRUE);
map.put("three", new Integer(1));
JSONObject json = JSONObject.fromObject(map);

JsonBean jb=new JsonBean()
JSONObject jsonObject = JSONObject.fromObject(jb);

int [] arr = new int[] { 1,2,3};
JSONArray jsonarray = JSONArray.fromObject(arr);

JSONArray jsonarr = JSONArray.fromObject("['json','is','easy']" );

String jsonStr =   "{\"id\": 2," +
" \"title\": \"json title\", " +
"\"config\": {" +
"\"name\": 34," +
"\"type\": 35," +
"}, \"class\": [" +
"\"one\", \"two\", \"three\"" +
"]}";
//转换成为JSONObject对象
JSONObject jsonObj = new JSONObject(jsonStr);
