環境: JDK 1.6、JEE5 Hibernate Core 3.3.1.GA、Hibernate Annotations 3.4.0.GA DB: Informix

リバース エンジニアリングを使用して、db スキーマから永続化エンティティを作成しました [注: これは作業中のスキーマであり、変更できません]

basic_auth_accounts org.hibernate.TypeMismatchException のリストを選択すると例外が発生する: クラス ebusiness.weblogic.model.UserAccounts に間違ったタイプの ID が提供されました。予想: クラス ebusiness.weblogic.model.UserAccountsId、クラス ebusiness.weblogic.model.BasicAuthAccountsId を取得

basic_auth_accounts と user_accounts の両方に複合主キーと 1 対 1 の関係があります。ここで何をすべきか手がかりはありますか？これは、私がこれを機能させるために非常に重要です。ネット上で実質的な解決策を見つけることができず、hibernate が行った ID クラスを作成すると言う人もいれば、1 対 1 の関係を持たないと言う人もいます。

私を助けてください！！

クラスのメイン コードは次のとおりです。

オンラインでの検索/調査をフォローアップするためだけに：

私が見ることができるものから、同じ複合キーrealmTypeId、realmQualifier、およびaccountIdを使用する2つのテーブルbasic_auth_accountsとuser_accountsがあります。両方のエンティティには、これらの列と1対1の関係を持つ埋め込み可能なクラスがあります。

休止状態のツールを使用して、変更できないDBスキーマからこれらのエンティティを生成しました。

BasicAuthAccountsIdの名前をより一般的な名前に変更する場合のように、両方のエンティティに同じ埋め込み可能クラスを使用したかどうか疑問に思っています。UserAccountsIdを削除し、両方のエンティティに同じ@EmbeddedIdクラスを使用しますか？
