Spring and hibernate: No Session found for current thread

by

You annotated your Dao class with @Transactional, but not your service class. The line: Visitor storedVisitor = (Visitor) sessionFactory.getCurrentSession().get(Visitor.class, visitorDetails.getTfscNumber(), LockMode.NONE); requires you to be in a transaction. You can fix this by adding the @Transactional annotation to your ProfileService class, or just the registerVisitor() method.

Hibernate SessionFactory vs. JPA EntityManagerFactory

by

Prefer EntityManagerFactory and EntityManager. They are defined by the JPA standard. SessionFactory and Session are hibernate-specific. The EntityManager invokes the hibernate session under the hood. And if you need some specific features that are not available in the EntityManager, you can obtain the session by calling: Session session = entityManager.unwrap(Session.class);
