Hibernate 5.0.0 - Mapping in hibernate.cfg.xml ignored?

[A. Koch]

Hi everybody,

I am quite new to hibernate and was using version 4.3 until now. I upgraded to 5.0.0, as I wanted to take advantage of the Java 8 features.

I have no annotations in my code and use the "hibernate.cfg.xml"-file with ".hbm.xml"-files for each persisted class. Until now, everything worked fine, but since the upgrade, my mappings in "hibernate.cfg.xml" seem to be totally ignored...

Doing a query leads to

WARN: HHH000183: no persistent classes found for query class: FROM adresse.Absenderdaten

Doing a save or update operation leads to

 org.hibernate.MappingException: Unknown entity: adresse.Absenderdaten

Everything works fine, when I add the resources programatically in the configuration with

Configuration configuration = new Configuration().addClass(adresse.Abenderdaten);

Unfortunately, this process takes more then a second for each persisted class, which wasn´t the case earlier with the config-file...

Can anybody tell me, why the mapping in the "hibernate.cfg.xml"-file doesn´t seem to work anymore? It is definitely read, as other parameters are recognized.

Thank you for any advice
Andy

Excerpt from SessionFactory

Configuration configuration = new Configuration();
configuration.configure("hibernate.cfg.xml");
serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);

(sorry for this cross-posting from https://forum.hibernate.org/viewtopic.php?f=1&t=1041405 - this forum seems to be flooded with spam right now )

Can you try this to create your SessionFactory:

	final StandardServiceRegistry registry = new StandardServiceRegistryBuilder()
			.configure() // configures settings from hibernate.cfg.xml
			.build();
	try {
		sessionFactory = new MetadataSources( registry ).buildMetadata().buildSessionFactory();
	}
	catch (Exception e) {
		// The registry would be destroyed by the SessionFactory, but we had trouble building the SessionFactory
		// so destroy it manually.
		StandardServiceRegistryBuilder.destroy( registry );
	}

Great, this seems to work fine . In addition to your proposed code I only had to change <session-factory name=""> to <session-factory> in my "hibernate.cfg.xml", as I got a JNDI-naming Exception. Thank you very much!!!

Is there any note in the official documentation, that using "configuration.buildSessionFactory(serviceRegistry);" does not work as expected? I couldn´t find any...
