Since the release of Java 8, I get this question quite often. Unfortunately, Hibernate and JPA 2.2 don’t support Optional as an attribute type. But with a little trick, you can still use Optional as the return type of your getter methods. If you annotate the primary key attribute with an @Id annotation, you tell Hibernate to use field access to set and retrieve the entity attribute values. That means that Hibernate doesn’t call the getter or setter methods and that you can implement them in any way you like. So, you can wrap the optional attribute into an Optional instead of returning it directly. If you like this video, please give me your thumbs up and share it with your friends and co-workers.
