How to handle JPA annotations for a pointer to a generic interface

Question

I have a generic class that is also a mapped super class that has a private field that holds a pointer to another object of the same type:

@MappedSuperclass
         


        

Answer 1

You can add a @OneToOne(targetEntity=SuperClassOfT.class) to your fields to make this work.
