Wie kann ich eine ID in einem zusammengesetzten Primärschlüssel in Hibernate automatisch erhöhen?

Wie ich im Kommentar erwähnt habe, habe ich @IdClass verwendet es hat funktioniert, während ich es in hsqldb versucht habe In-Memory-Datenbank, funktionierte aber nicht in mysql .

Bitte beachten Sie, dass ich hibernate 5 verwende

Sie können es mit Orakel versuchen, ich konnte mich nicht erinnern, aber es sollte funktionieren. Aber bitte überprüfen Sie, ob es irgendwelche Nachteile mit dem Ansatz gibt, falls vorhanden.

Das Folgende ist der error bekomme ich, während ich es mit MySql versuche

Ich habe es mit akzeptierter Antwort in der PostHibernate-Einfügung schlägt fehl, wenn eingebetteter Schlüssel Identitätsspalte auf SQL Server enthält aber kein Glück damit.
