Configuration class:
public class SessionManager {
public static SessionFactory configure(){
return new Configuration().configure("hibernate.cfg.xml") // 9 line
.buildSessionFactory();
}
}
Main:
SessionFactory sessions = SessionManager.configure(); // 18 line
Session session = sessions.openSession();
