Hibernate: Used mappedBy on class that extends another class annotated as JoinedSubclass?

Question

The following doesn\'t work:

@Entity
class Owner {

  @OneToMany(mappedBy=\"owner\", cascade = {CascadeType.ALL})
  protected Set getBSet() {
    ..
  }         


        

Answer 1

I'd double check your real implementation. I used your sample code and after adding an @Id everything worked as expected. Even IntelliJ says getBSet() is associated with B.owner.

Answer 2

Try adding targetEntity = Transaction.class. This worked for me when I was using SINGLE_TABLE inheritance. I didn't try it with JOIN.

@Entity
class Owner {

  @OneToMany(mappedBy="owner", cascade = {CascadeType.ALL}, targetEntity = Transaction.class)
  @Where(clause = "tableType='I'")
  protected Set<B> getBSet() {
    ..
  }

}

Answer 3

It's a Hibernate oddity, but it's deliberate. I have a blog post up with background information, links and a workaround for the JOINED solution.
