Hi,
I have the problem, that when I use an @Embedded object within my
inheritance-strategy,
the entities will not be fetched correctly. When I change the annotation to
@Transient,
all corresponding entities are fetched correctly.
This is an example of my class structure:
| @Entity
| @Table(name="baseClass")
| @Inheritance(strategy=InheritanceType.JOINED)
| public abstract class BaseClass implements Serializable {
| ....
| }
|
|
| @Entity
| @Table(name = "extendedClass")
| @PrimaryKeyJoinColumn(name="id_baseClass")
| public class ExtendedClass extends BaseClass {
|
| ...
|
| @Embedded //@Transient works
| private EmbeddableClass embedded = null;
| }
|
| @Entity
| @Table(name = "anotherExtendedClass")
| @PrimaryKeyJoinColumn(name="id_baseClass")
| public class AnotherExtendedClass extends BaseClass {
|
| ...
| }
|
|
| @Embeddable
| public class EmbeddableClass implements Serializable {
|
| @Column
| private boolean aValue;
|
| @Column
| private boolean anotherValue;
|
| }
|
| @Entity
| @Table(name = "users")
| public class User extends SimpleUser implements Serializable {
|
| @OneToMany(mappedBy = "anotherEntity", cascade={CascadeType.ALL},
fetch=FetchType.LAZY)
| private Collection<BaseClass> baseClassCollection = new
Vector<BaseClass>();
| }
|
|
So when I keep the @Embedded-Annotation, I have all objects of the
ExtendedClass, but none
of the AnotherExtendedClasses. Together with the @Transient-annotation, I
receive all entities
of all inherited-classes from the database.
Anyone having an idea, why this is not working?
Thanks
Thomas
