Hibernate - Foreign keys instead of Entities

Question

Currently, Hibernate allows me to load objects defined by *-to-one relationships directly with

entity1.getEntity2()

Is it possible to get

Answer 1

Long fk = entity1.getEntity2().getId();

This should work. It would only not work if you have composite, primary keys being referenced as foreign keys but your solution wouldn't work either in that case. Considering my solution, even a composite key wouldn't look that ugly.

Long fkField1 = entity1.getEntity2().getCol1();
String fkField2 = entity1.getEntity2().getCol2();

Something like that will work.

EDIT: Thinking about your proposed solution more, it wouldn't work anyway because Hibernate already tries to automatically create a FK field for a Mapped relationship, so defining another @Column would simply try to bind to a second column with the same name.
