sql - 単項テーブルの HQL クエリ

Question

以下のような user_info テーブルがあります

ご覧のとおり、スーパーバイザーの列は同じテーブルを参照しています。

私は開発に Netbean を使用しています。私のPOJOは次のクラスを作成しました

アプリケーションにスーパーバイザーの名前を表示したい。Workbench で完全に機能する SQL コマンドを作成しました。

select e.user_name from user_info e, user_info s where e.user_id=s.supervisor

しかし、問題は、HQL で記述しようとしたときに、UserInfo クラスの Netbean によって作成されたそれぞれのメソッドがないことでした。

誰かがこの問題から解決策を見つけるのを手伝ってくれますか?
