Began to study Hibernate. I receive the following message:

  • It is not clear what the problem is? Heber does not connect to the database or what? All I see in the logs are warnings, but not errors - Alex

Try the following code in the class where SessionFactory registered:

 import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration; public class HibernateUtil { private static SessionFactory sessionFactory = null; static { Configuration cfg = new Configuration().configure(); } public static SessionFactory getSessionFactory() { return sessionFactory; } public static void shutdown() { // Close caches and connection pools getSessionFactory().close(); } }
