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

If you want your relationship unidirectional i.e. can navigate from Contact to Phone's only, you need to add

@JoinColumn(name = "contact_id", nullable = false)

Under your @OneToMany on your parent entity.

nullable = false IS VITAL if you want hibernate to populate the fk on the child table
