问使用Hibernate持久化接口集合

EN

@Entity
@Table(name = "zoo") 
public class Zoo {
    @OneToMany
    private Set<Animal> animals = new HashSet<Animal>();
}

// Just a marker interface
public interface Animal {
}

@Entity
@Table(name = "dog")
public class Dog implements Animal {
    // ID and other properties
}

@Entity
@Table(name = "cat")
public class Cat implements Animal {
    // ID and other properties
}

Use of @OneToMany or @ManyToMany targeting an unmapped class: blubb.Zoo.animals[blubb.Animal]
