Hibernate mapping, on a unmapped class

Question

Hi,

I' ve got 2 tables... Challenge and ChallengeYear, ChallengeYear is only to create a list of years in challenge.

I only want to make Challenge an entity, containing a list of List years. Is this possible?

I've looked in to @SecondaryTable together with @JoinColumn and @OneToMany, but neither of those can do the trick, or i am overlooking something.

Can someone help me?

Greetings, Jan

Answer 1

What is Year in your model, is it an Integer ?

if yes, you may annotate your Challenge.getYears method with @CollectionOfElements

like:

  @CollectionOfElements
  @JoinTable(
    table=@Table(name="ChallengeYear"),
    joinColumns = @JoinColumn(name="challengeId")
  )
  @Column(name="year", nullable=false)
  List<Integer> getYears() {
    ...
