Hello.
I'm in a situation where Hibernate has a particular behaviour, and TopLink has a different one.
My whole project can be found here:
http://dspace-sandbox.googlecode.com/svn/prototypes/hibernate-prototype/trunk/dspace-api/src/main/java/org/dspace/ (look in /content and in /core).
I have two entities, Item and Bundle, they extend the class DSpaceObject. There's a OneToMany relationship between them, Item has a list of Bundle objects and a method called createBundle(). I use Property Access with only JPA standard annotations (no org.hibernate imports). Here's a snippet of the relevant code (I omit setter methods too):
Code:
@MappedSuperclass
public abstract class DSpaceObject {
protected int id;
@Id
@GeneratedValue(strategy=GenerationType.SEQUENCE)
public int getId() {
return id;
}
}
Code:
@Entity
public class Item extends DSpaceObject {
private List<Bundle> bundles;
public Item() {
this.bundles = new ArrayList<Bundle>();
}
@OneToMany(cascade = { CascadeType.ALL }, mappedBy = "item")
public List<Bundle> getBundles() {
return bundles;
}
public Bundle createBundle() {
Bundle bundle = BundleFactory.getInstance(context);
bundle.setItem(this);
getBundles().add(bundle);
return bundle;
}
}
Code:
@Entity
public class Bundle extends DSpaceObject {
private Item item;
@ManyToOne
public Item getItem() {
return item;
}
}
I use a class called ApplicationService, that uses javax.persistence.EntityManager to perform CRUD operations for Item and Bundle (and much more..). I paste the important part:
Code:
public class ApplicationService {
private EntityManagerFactory emf = Persistence.createEntityManagerFactory(persistentUnit);
private EntityManager em;
public <T> T get(Class<T> clazz, int id) {
setupTransaction();
T result = em.find(clazz, id);
return result;
}
public <T> void update(Class<T> clazz, T object) {
setupTransaction();
em.merge(object);
}
public void commit() {
EntityTransaction tr = em.getTransaction();
try {
tr.commit();
} finally {}
}
public void complete() {
EntityTransaction tr = em.getTransaction();
try {
tr.commit();
}
finally {
em.close();
}
}
private void setupTransaction(String method) {
if(em==null || !em.isOpen()) {
em = emf.createEntityManager();
}
if(em.getTransaction()==null || !em.getTransaction().isActive()) {
EntityTransaction tr = em.getTransaction();
tr.begin();
}
}
}
Now, the problem: I tried to run this test
Code:
ApplicationService applicationService = new ApplicationService();
Item item = applicationService.get(Item.class, 50);
Bundle bundle = item.createBundle();
bundle.setName("bundle");
applicationService.update(Item.class, item);
applicationService.complete();
Using Cascade, I expected to have a new bundle persisted on the DB, with a reference to the item. Actually, two bundles are persisted! I find two new lines on the table, referring to the same item_id.
Looking at the debugging messages of hibernate, i found that one id for the bundle is generated when em.merge is called, and then another one when tr.commit is called: two ids generated, two bundles persisted.
Another thing I noticed: I have this problem only when hibernate is in LAZY, if I set EAGER only one bundle is persisted.
The weird thing is: I tried also to use Toplink instead of Hibernate, this problem does not exist! only one bundle is persisted!
I paste the long console-output of the test:
Code:
