spring 3.1とhibernate 3.6を使用して、案内広告の Web サイトに取り組んでいます。4 つのエンティティ ( User、UserRole、AdvertisementおよびCategory) があります。クラスごとに個別のdaoを使用しています。Daos forUserおよびfor のすべての操作は正常にUserRoles機能します。Advertisementしかし、およびのdaosCategoryでは、保存/更新はSQLGrammarException.

ManytoOne 関連付けを削除しようとしましたが (USER_ID および CAT_ID FK を削除)、これら 2 つのテーブルに保存できません。しかし、 Advertisement クラスのオブジェクトは を呼び出すことで取得でき、advertisementDao.getAdById(id)関連する Category オブジェクトと User オブジェクトも自動的に読み込まれます。また、4 つのクラスすべてを hibernate 構成ファイルに追加しました。
このエラーの原因がわかりません。最後に、セッションから Query オブジェクトを取得して、従来の方法で SQL Insert クエリを作成しようとしました。また、これと同じエラーが発生します。私を助けてください。ありがとうございました
