プロジェクトで Eclipse で休止状態ツール スキーマ エクスポートを実行すると、次のエラーが表示されます。同じコレクションをマッピングしているように見えますが、そうではありません。これに対する解決策はありますか、使用すべき注釈はありますか、またはコレクションが同じではないことを構成ファイルで指定する方法はありますか? この問題を解決する方法についてアドバイスや提案をいただければ幸いです。以下は、エラーのコードとスタック トレースです。さらに情報が必要な場合はお知らせください。

問題は、クラス<generator class="increment"/>でを忘れていることです。 だからこれを試してください：idField


@Id
@GenericGenerator(name="gen",strategy="increment")
@GeneratedValue(generator="gen")
@Column(name = "ID", unique = true, nullable = false, precision = 15, scale = 0)
private Long id;
