Hibernate JPA @Parent Example

The @Parent annotation is used to specify that the currently annotated embeddable attribute references back the owning entity.

Parent Reference the property as a pointer back to the owner (generally the owning entity).

@Parent mapping
The Hibernate-specific @Parent annotation allows you to reference the owner entity from within an embeddable.
