@NaturalId does not work if applied to an inherited field.
In fact when trying to load
{{Section section = session.bySimpleNaturalId(Section.class).load(name);}}
an exception is thrown.
I tried several variants with repeating the name, @AnnotateOverwrite, getter with and without setter, adding the @NaturalId to the super class - nothing worked.
From my understanding it could and should work as long as the derived entities do not share the same table space.
{{
@MappedSuperclass
public abstract class BasicEntity implements Serializable {
private static final long serialVersionUID = 1L;
private Long id;
private String name;
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "seqEntities")
@SequenceGenerator(name = "seqEntities", sequenceName = "seqEntities")
public Long getId() {
return id;
}
protected void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
@Entity
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
@NaturalIdCache
public class MyEntity extends BasicEntity {
private String name;
@NaturalId
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
}} |
