Get previous version of entity in Hibernate Envers

Question

I have an entity loaded by Hibernate (via EntityManager):

User u = em.load(User.class, id)

This class is audited by Hibernate Enve

Answer 1

maybe this then (from AuditReader docs)

AuditReader reader = AuditReaderFactory.get(entityManager);
User user_rev1 = reader.find(User.class, user.getId(), 1);

List revNumbers = reader.getRevisions(User.class, user_rev1);
User user_previous = reader.find(User.class, user_rev1.getId(),
  revNumbers.get(revNumbers.size()-1));

(I'm very new to this, not sure if I have all the syntax right, maybe the size()-1 should be size()-2?)
