Need a QuickStart for Spring + Hibernate

[vbforums]

Hi Adam,

Thanks for developing Envers, the great way for Entity Versioning.

I need couple of help from you

1. Can you please post a QuickStart guide for Spring + Hibernate users. Currently I am not sure where to inject your beans.

2. What will be the supporting Jars needed for Envers to work, Do I need to have the hibernate-entity manager jar for Envers to work

Your help on this is much appreciated.

Thanks,

Hello,

I never used Spring, but if anybody would like to contribute such a guide, I'll post it on the website :)

Concerning the JARs, you'll need hibernate entity manager, as it's a dependency of the VersionsReaderFactory. I guess it would be better if there were separate factories for pure hibernate and jpa-hibernate, so that you wouldn't have always to bundle hibernate entity manager when not using it.

And if you don't user JPA, then I guess you'll need hibernate annotations :).

Hi Adam,

Thanks for your response.

1. Can you please let me know the primary class name which I need to instantiate and is this an Hibernate Event listener or interceptor.

3. Will Envers work in WLS environment.

Hello,

you don't instantiate anything, you just need to use VersionsReaderFactory. Please see the quickstart: https://www.jboss.org/envers/quickstart.html.

Envers will work wherever Hibernate works, so also in a WLS environment.

Envers does not need anything more than you would use to get Hibernate EntityManager and Spring working.
I use JpaTemplate and JpaDaoSupport so you would use like:

getJpaTemplate().execute(new JpaCallback() {
 public Object doInJpa(EntityManager em) throws PersistenceException {
 VersionsReader reader = VersionsReaderFactory.get(em);
 // your code here
 }
}
