Hello

Hibernate version:3.1

Mapping documents:Annotation

Code between sessionFactory.openSession() and session.close():
User u = new User();
u.setUsername("test_user");
u.setPassword("test_pass");

userDao.save(u);


Full stack trace of any exception that occurs:No Exception

Name and version of the database you are using:MySql 4

I create a pre insert event listener to set a date/time field and the user name who is going to insert this record. but it doesnt work



the event has been fired but no changes applied.

would you help me out?

regards
Mohammad

did U figure out how to do this?

seems like no-one is interested in pre-insert/pre-update issues
I have found a lot of questions in forums and in the web abouth this, but no answers...

Hi
actually I can't remember what I did at that time. perhaps I left it but as far as I know if you are using Hibernate 3.1 you can use @PrePersist and @PreUpdate annotations that they come from EJB 3 and I think it will work fine.

as an example:

tx for the answer

I know about those annotation, but that would mean, that I have to put them on every entity that wants to write a history
or maybe it would work if I put it on a common superclass of all entities that want to keep a history

what my prefered method is:

• the entities that are interested in historical data must implement a special interface (e.g. Historical)
• there is a pre-insert and pre-update event listener, that will be called for all entities: inside this lisitener, I only need to check if the entitiy is an instance of my Historical inteface

I already got that working, but still have a problem, that is a bit like your's:
when I create my entity it's like that:

• pre-insert event listener is called
• Historical data is set on the entity (I checked this in the debugger)
• hibernate issues a sql-insert command: but without the data that has been set in teh pre-insert event listener!
• hibernate now issues an update command and sets the historical data that has been set in the pre-insert event listener

that sounds a lot like what you have encountered in your original post

I have already tried to find more information on this, but didn't find anything that would help me
the API doc of the PreInsertEventListener does not even mention what the expected returnvalue means!
http://www.hibernate.org/hib_docs/v3/api/org/hibernate/event/PreInsertEventListener.html

I have a prePersist listener set up on the superclass of all my entities but it is ignored. It looks very similar to your situation.

I have a 'modified' field on the superclass which the prePersist callback should set to the current datetime.

This is using hibernate-entitymanager-3.3.1ga and hibernate core 3.2.5.

There's no related issue in Jira that I can see. If nobody says otherwise, I'll open one for it.

+1 from me for the jira.

I got that working now.
I extend org.Hibernate.EmptyInterceptor and override onSave and onFlushDirty.
Both cases work as expected, now.
