Ich möchte separate Sequenznamen für Produkt und Bestellung. Wie soll ich das mit JPA @SequenceGenerator machen und nicht mit Hibernate-Klassen?
Siehe: https://jakarta.ee/pecifications/persistence/2.2/apidocs/javax/persistence/sequencegenerator< /p>
Vorhandener Code war so und funktionierte einwandfrei, aber er nutzte die Hibernate-Implementierung und war veraltet
[code]- @GenericGenerator(name = "id_gen", type = org.hibernate.id.enhanced.SequenceStyleGenerator.class,
- parameters = { @Parameter(name = SequenceStyleGenerator.CONFIG_SEQUENCE_PER_ENTITY_SUFFIX, value = "_seq"),
- @Parameter(name = SequenceStyleGenerator.INITIAL_PARAM, value = "1"),
- @Parameter(name = SequenceStyleGenerator.INCREMENT_PARAM, value = "1") })
+ @SequenceGenerator(name = "id_gen", sequenceName = "entity_seq", initialValue = 1, allocationSize = 1)
