map 对象转 list对象

    List list = new ArrayList<>();
    HashMap map = new HashMap<String,Object>();
    map.put("name", "张三");
    map.put("age", 20);
    list.add(map);

    JSONArray result = JSONArray.fromObject(list);
    List<User> jsonDtosList = (List<User>) JSONArray.toCollection(result, User.class);

导包  import net.sf.json.JSONArray
