> There is currently no way to specify (user friendly) foreign key name on table with shared primary key used in One-to-One mapping. The most intuitive way would be to
> accept @ForeignKey on property level (see the comment in the code below) or on entity level (similar way to usage in joined inheritance) or last option may be add parameter in foreign generator.
> {code}
> @Entity
> public class ExampleEntity implements Serializable {
> @Id
> @GenericGenerator(name = "foreign-generator", strategy = "foreign", parameters=@Parameter(name="property", value="parentExampleEntity"))
> @GeneratedValue(generator = "foreign-generator")
> private Long id;
> ...
> @PrimaryKeyJoinColumn
> @OneToOne(fetch=FetchType.LAZY, optional=false)
> @org.hibernate.annotations.ForeignKey(name="parent_entity_fk") // this is currently ignored
> private ParentExampleEntity parentExampleEntity;
> ...
> }
> {code}
