JPA not saving foreign key to @OneToMany relation

Question

I\'m using Spring with Hibernate as a JPA provider and are trying to get a @OneToMany (a contact having many phonenumbers) to save the foreign key in the phone numbers table

Answer 1

Try this sample:

@Entity
public class Contact {
    @Id
    private Long id;

    @JoinColumn(name = "contactId")
    @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true)
    private Set phones;
}

@Entity
public class Phone {
    @Id
    private Long id;
    private Long contactId;
}
