Hibernate and Spring sessionFactory null and db not created

Question

I get some problem while trying to integrate Spring with Hibernate. From the log it seems the tables and the database is created, but I can't find the database file and while inspecting the sessionFactory I get nullpointer exception, and I can't really understand what's going on.

These are my configuration files:

• web.xml

  <beans:bean id="utenteDao"
      class="org.fabrizio.fantacalcio.model.dao.UtenteDaoImpl"> 
  </beans:bean>
  

In my BaseDaoImpl I have the following code:

@Repository
public class BaseDaoImpl<T> implements BaseDao<T> {

//  private static final Logger logger = LoggerFactory
//          .getLogger(BaseDaoImpl.class);

    @Autowired
    private SessionFactory sessionFactory;

    private Session getSession() {
        return sessionFactory.getCurrentSession();
    }

The log generates these messages, resulting in null sessionFactory and no db file generated:

If someone could review my xml code formatting I would appreciate, as It doesn't show properly.

EDIT: This is UtenteDaoImpl class, it does nothing as it inherits stuff from BaseDao.

@Repository
public class UtenteDaoImpl extends BaseDaoImpl<Utente> implements UtenteDao{

}

Answer 1

Please change sessionFactory to protected.

@Autowired
protected SessionFactory sessionFactory;
