Hibernate how to get updated properties

Question

How to get which properties were updated after hibernate update? For example if I got

SomeEntity se = new SomeEntity();
getHibernateTemplate().save(se); 

//then in some other method
se.setProp1("some new value");

//then in 3th method
getHibernateTemplate().update(se);

If you tell hibernate to do dynamic update it will know witch properties were changed and update only them. Is there a way to get the ones that were changed or to check is specific property was changed?

Don't know if useful but have a look at this [old stackoverflow topic](http://stackoverflow.com/questions/14125558/hibernate-envers-get-fields-that-have-changed) — Paolo, Nov 08 '13 at 16:45

Ended up doing native sql query to compare the state in the db with the state in the entity before flush the session.

Query query = session.createSQLQuery(
"select t.someProp1 from someTable t where t.id = :entityId")
.setParameter("entityId", entity.getId());
List result = query.list();
