List转JSONArray和JSONArray转List

1.List转JSONArray

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

 

2.JSONArray转List

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

3.String转JSONArray

String st = "[{name:Tim,age:25,sex:male},{name:Tom,age:28,sex:male},{name:Lily,age:15,sex:female}]"; JSONArray tableData = JSONArray.parseArray(st);
String dUserInfoDto="[1,2,3]"

List<Long> list = JSONArray.parseArray(dUserInfoDto,Long.class);
