このエラーが発生しています。
org.hibernate.MappingException: Could not determine type for: dom.Whore, at table: Message, for columns: [org.hibernate.mapping.Column(receiver)]
これは、テーブルにマップされているクラスです。

これは、タイプを判別できないクラスです。

フィールドとゲッターに同時に注釈を設定しないことに関係しているという多くの投稿を読みました。しかし、ご覧のとおり、それが原因ではありません。私は困惑しています。

また、送信者と受信者のゲッターで @ManyToOne を使用してみました。しかし、これは何の違いもありませんでした。
