JAVA LIST、JSONArray转换

1.JSONArray转List
JSONArray array = new JSONArray();
List<Student> list = JSONObject.parseArray(array.toJSONString(), Student.class);

2.List转JSONArray
List<T> list = new ArrayList<T>();
JSONArray array= JSONArray.parseArray(JSON.toJSONString(list))；

3.String转JSONArray
String st = "[{name:XiaoXiao,age:25},{name:MingMing,age:12},{name:Lily,age:21}]";
JSONArray tableData = JSONArray.parseArray(st);
