Can one table in Hibernate inherit the ID of a second table?

Question

Java

I have the entities described below (PartnerInformation, Activity, Address), how can I make the Activity and Address entities inherit id from PartnerInformation?

@Data
@Entity
@Builder
@AllArgsConstructor
@NoArgsConstructor
@JsonNaming(PropertyNamingStrategies.UpperSnakeCaseStrategy.class)
public class PartnerInformation {

    @Id
    @GeneratedValue(generator = "UUID")
    @GenericGenerator(
            name="UUID",
            strategy = "org.hibernate.id.UUIDGenerator"
    )
    @JsonIgnore
    private UUID id;

    @JsonProperty("ID")
    public  String externalId;
    private boolean isActive = true;

    @OneToOne(cascade=CascadeType.ALL)
    private Activity activity;

    @OneToMany(cascade=CascadeType.ALL)
    private List<Address> address;
}

Good afternoon.
So maybe you do not need a OneToOne connection, but you need @Embeddableit for an Activity and instead of a OneToMany connection for a List, use @ElementCollectionor @CollectionOfElementsfor List<Address>

If you want to embed an ID, you can probably look at @EmbeddedId https://www.baeldung.com/spring-jpa-embedded-metho...
