テーブルで「シンプル」を実行していたところ、このエラーが発生しました。ネットを検索しても役に立ちませんでした。

主キーのソースとしてシーケンスを使用して接続されていると思います。

助けていただけますか？ありがとう

実行しようとしているコード (エラーをスローする部分を強調表示しました)

    EventRegistration eventRegistration = new EventRegistration();

私は同じ問題で立ち往生していました。ついに抜け道を見つけた。この行を hibernate.cfg.xml ファイルに入れます。

<property name="hibernate.jdbc.use_get_generated_keys">true</property>

その参照と説明は、次の場所にあります。
