Ich versuche, meine Java-Play-Anwendung mit Hibernate Orm zu integrieren und hier ist meine Projektstruktur.Play Framework 2.6.x Integration mit Hibernate Orm 4.3.1 Mapping-Fehler
Wie Sie sehen können, habe ich meine POJOs in einem Paket models und hibernate.cfg.xml innen conf genannt platziert.
hibernate.cfg.xml
<?xml version='1.0' encoding='utf-8'?>

HibernateUtil Klasse: (innen services)
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
try {
// Create the SessionFactory from standard (hibernate.cfg.xml)
// config file.
sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Log the exception.
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
Controller-Klasse
public class LoginController extends Controller {
public Result login() throws SQLException {
Session s = HibernateUtil.getSessionFactory().openSession();
Criteria c = s.createCriteria(Coating.class);
c.add(Restrictions.eq("code", "CO3444"));
Coating co = (Coating) c.uniqueResult();
String title = co.getTitle();
s.close();
return ok(views.html.login_page.login.render(title));
}
}
Alles scheint gut für mich und sobald ich die Anwendung kompilieren und ausführen, beendet es den Anwendungsserver mit unten Fehler.

AKTUALISIERT
Aber sobald ich alle Zuordnungen von hibernate.cfg.xml entfernen und den LoginController Code unten ändern:
Session s = HibernateUtil.getSessionFactory().openSession();
Connection c = s.getSessionFactory().getSessionFactoryOptions().getServiceRegistry()
.getService(ConnectionProvider.class).getConnection();
//Criteria c = s.createCriteria(Coating.class);
//c.add(Restrictions.eq("code", "CO3444"));
//Coating co = (Coating) c.uniqueResult();
//String title = co.getTitle();
//s.close();
String title = c.getMetaData().getDatabaseProductName();
return ok(views.html.login_page.login.render(title));
Anwendung startet und läuft gut in der Browser mit der Ausgabe MySQL Das bedeutet, es gibt keine Winterschlaf Konfigurationsfehler und keine Fehler mit der HibernateUtil Klasse entweder.
Jede Hilfe wäre nennenswert. Vielen Dank.
