public class GroupFan<T> { private Long id; private String name; private List<T> users = new ArrayList<T>(); }
}GroupFan<User> group3 = JSON.parseObject(jsonString, GroupFan<User>.class);这种写法会报错，fastjson支持解析泛型吗
GroupFan<User> group3 = JSON.parseObject(jsonString, GroupFan<User>.class);

GroupFan<User> group3 = JSON.parseObject(jsonString, new TypeReference<GroupFan<User>>(){});这种方式反序列化后，里面的users的size永远都是0，这是为何？@wenshao
GroupFan<User> group3 = JSON.parseObject(jsonString, new TypeReference<GroupFan<User>>(){});
