Access SessionFactory from Spring Boot Application

I am trying to get access to the Hibernate session factory but am getting the following error at the line mentioned.

No CurrentSessionContext configured!

code

@Service
@Transactional
public class GenericSearchImpl implements GenericSearch {

    @Autowired
    private EntityManagerFactory entityManagerFactory;

    @Override
    @SuppressWarnings("unchecked")
    public <T> List<T> search(final Class<T> type, final String[] criteriaList, final int page, final int perPage) {
        Session session = getSession();
        ...
    }

    public Session getSession() {
        final HibernateEntityManagerFactory emFactory = (HibernateEntityManagerFactory) entityManagerFactory;
        final SessionFactory sessionFactory = emFactory.getSessionFactory(); 
        return sessionFactory.getCurrentSession(); //ERROR No CurrentSessionContext configured!

          //This worked but I understand it to be BAD as spring should be managing open sessions.
          //        try {
          //            return sessionFactory.getCurrentSession();
          //        } catch (Exception e) {
          //            return sessionFactory.openSession();
          //        }
    }

    ...

}

Any idea why?
