Hibernate PostInsertEventListeners -Use Same Transaction as insert?

seems to work fine I dont think this is possible.
If I understand, you want to execute some code only if the transaction completed successfully (was commited). However, if the transaction is commited, you can't do something else in the same transaction since it's ended.

Hibernate retrieves OLD data after transaction insert

help you fix your problem It's hard to diagnose the exact problem because you don't say when you close sessions, and in which session/transaction you get your User. But I guess the problem comes from the fact that you don't maintain the two sides of the relationship when inserting a new registration.
You should set the user in the registration, and add the registration to the list of registrations of the user.

Transaction, hsql, hibernate. No insert ---> Could not synchronize database state with session

Does that help After a while, I came back to this problem. I have realized, that the problem was not related with the store method itself. In my test method I had something like:
code :
public void testCreateAnnotation() throws Exception {

  //Store the mediaObject related with the annotations to be created

    //Store annotation

    public void testCreateAnnotation() throws Exception {

      //Store the mediaObject related with the annotations to be created

//        annotationService.createAnnotation(MockGenericAnnotationDataPool.TEST_ANNOTATION1);


    public void testUpdateAnnotation() throws Exception {

        //Store the mediaObject related with the annotations to be created
//      mediObjectService.storeMediaObject(MockGenericMediaObjectDataPool.GENERIC_MEDIA_OBJECT1);

        GenericAnnotation geOriginalAnnotation = annotationService.createAnnotation(MockGenericAnnotationDataPool.TEST_ANNOTATION1);


Why can I insert/update data with hibernate even when there's no transaction involved?

it fixes the issue Hibernate doesn't need transactions, the most common problems in database-based applications are just easier to solve with transactions which is why usually everyone uses transactions with Hibernate. But that's mere coincidence/convention/laziness.
All Hibernate needs is a java.sql.Connection and if your container provides one even though there is no current transaction manager configured, Hibernate is fine with that.

Hibernate Collection is always empty when performing insert and read in same method/transaction

hope this fix your issue Your car1 is this same object as it was before car2.setDefaultCar(car1), because car2.setDefaultCar(car1); updates only car2 instance. What you want, is to update car1 state (fetch changes from database), after storing car2 in database. To do it in one method, you need to flush() session (or commit) and call refresh(car1) method on car1 instance - it will be recreated from database.
But, there is other approach - first add car2 to car1 collection, and then just persist car1 - this will cause that car2 will be persisted also (when cascade="save-update" is set).

Spring JPA / Hibernate transaction force insert instead of update

With these it helps I never did that before, but a little hack, would maybe do the job.
There is a Persistable interface for the entities. It has a method boolean isNew() that when implemented will be used to "assess" if the Entity is new or not in the database. Base on that decision, EntityManager should decide to call .merge() or .persist() on that entity, after You call .save() from Repository.
