Hibernate：エンティティ内部クラスのデフォルトコンストラクターはありません
同様の質問がたくさんあることは承知していますが、これについては誰も助けてくれませんでした。
私はTynamoと呼ばれるCRUDフレームワークを使用しています。これは、ApacheTapestryとHibernateに依存しています。コンポジット/コンパウンド主キーを持つテーブルでCRUDに使用しようとする場合を除いて、これはすべて正常に機能します。
フレームワークではまったく機能しないようであるため、@EmbeddedIdルートを使用しないことにしました。そうは言っても、私は@IdClassメソッドを使用してきましたが、これはほとんど機能しています。私は成功から1、2行のコードだと思います。
問題は、リフレクションを使用してオブジェクトを構築し始めると、その内部クラスのパブリックな空のコンストラクターが実際に存在するにもかかわらず、爆発してorg.hibernate.InstantiationException: No default constructor for entity: ...と言うことです。
回答するときは、コードスニペットを避け、完全なクラスなどを使用して、このスレッドにアクセスする他のユーザーが何が起こっているのかをより完全に把握できるようにしてください。

裏では、TransferExtensionPKは内部クラスであるため、実際にはデフォルトのコンストラクターはありません。内部クラスを構築するには、外部クラスのインスタンスが必要であるため、コンパイラーは、パラメーターなしのコンストラクターを、TransferExtensionのインスタンスを受け入れる1パラメーターのコンストラクターに変換しました。
この問題を修正するには、TransferExtensionPKを内部クラスではなく、単にネストされたクラス（静的）にします。
public static class TransferExtensionPK // etc
