Looking for a not-deprecated session-factory

Question

I am dealing with hibernate and as I opened my current project I figured out my Session-Factory is deprecated:

AnnotationConfiguration af = new AnnotationConfiguration();
SessionFactory factory = af.configure().buildSessionFactory();
Session session = factory.openSession();

AnnotationConfiguration seems to be deprecated by now... So I checked the JavaDoc and I got told it moved to:

org.hibernate.cfg.Configuration

My code works fine so far, actually I don't want to change it... But I googled and found someone who's asking himself the same question whythe SessionFactory needs to be changed... http://rgordon.co.uk/blog/2012/02/24/hibernate-please-dont-deprecate-yourself/

The Article is from 2012 (so not that old...) and describes everything in that way:

ServiceRegistryBuilder serviceRegistryBuilder = new ServiceRegistryBuilder();
serviceRegistryBuilder.applySettings(properties);
ServiceRegistry serviceRegistry = serviceRegistryBuilder.buildServiceRegistry();

Configuration configuration = new Configuration().addClass(FeedTradePersistable.class);

SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);

I implemented that. The JavaDoc proves that wrong - again! Deprecated. It refers to:

org.hibernate.boot.registry.StandardServiceRegistryBuilder

I googled that again. The results weren't so satisfying...

I started to modify the code...

ServiceRegistry serviceRegistry = serviceRegistryBuilder.build();
Configuration configuration = new Configuration();
SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);
Session session = sessionFactory.openSession();

And an exception is thrown...

org.hibernate.HibernateException: Connection cannot be null when 'hibernate.dialect' not set

at line:

SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);

I am pretty sure this is because I haven't specified any configuration-settings. Actually, I don't want to. I feel comfortable with the hibernate.cfg.xml.

I played a bit around with configuration.addFile(.. - wasn't that successful...

Has anyone an idea about that? Thanks

UPDATE: (hibernate.cfg.xml)

UPDATE (16. Feb 2014): I think it is necessary to show you my pom.xml as well. It took me a while until I figured out which combination of the Hibernate-Framework works for me...

Answer 1

As I got some time to modernize my software I decided to put some effort into it and did some research:

http://www.codejava.net/frameworks/hibernate/building-hibernate-sessionfactory-from-service-registry provides a modern HibernateUtil:

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;

public class HibernateUtil {

private static SessionFactory sessionFactory;

public static SessionFactory getSessionFactory() {
    if (sessionFactory == null) {
        Configuration configuration = new Configuration().configure();
        ServiceRegistryBuilder registry = new ServiceRegistryBuilder();
        registry.applySettings(configuration.getProperties());
        ServiceRegistry serviceRegistry = registry.buildServiceRegistry();

        sessionFactory = configuration.buildSessionFactory(serviceRegistry);            
    }

    return sessionFactory;
}

}

Even though this version seems to work as well:

import java.util.logging.Level;
import java.util.logging.Logger;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class HibernateUtil {

private static final SessionFactory sessionFactory;

static {
    try {
        Configuration cfg = new Configuration();
        sessionFactory = cfg.configure("hibernate.cfg.xml").buildSessionFactory();
    } catch (Throwable ex) {
        Logger.getLogger(HibernateUtil.class.getName()).log(Level.SEVERE, null, ex);
        throw new ExceptionInInitializerError(ex);
    }
}

public static SessionFactory getSessionFactory() {
    return sessionFactory;
}

}

But my problem was I didn't want to integrate a new version with the old libs. After updating I ran into a

java.lang.NoSuchMethodError: org.hibernate.annotations.common.reflection.java.JavaReflectionManager.injectClassLoaderDelegate(Lorg/hibernate/annotations/common/reflection/ClassLoaderDelegate;)V

often. Annoying. Usually Mkyong provides good solutions, but in my case he wrote the opposite solution of Stackoverflow...

So I searched some repositories and found a shockingly easy solution (compare: http://hibernate.org/orm/downloads/):

<!-- HIBERNATE -->
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.0.0.Final</version>
</dependency>

Some other minor issues which stopped me: In the hibernate.cfg.xml I had to change the line from update to auto:

<property name="hbm2ddl.auto">auto</property> 

Compare it to my old pom.xml... - back then I had my first "encounter" with Hibernate and added everything which seemed useful until it worked. After it did so I stopped touching it for... Almost two years... Never change a "winning" team, right?

Answer 2

yes, in hibernate version 4. 3 both buildSessionfactory() and ServiceRegistryBuilder() are deprecated.

so u have change your coding like below to get session factory for hibernate version 4.3

public class HibernateSessionFactory {

private static final SessionFactory sessionFactory = buildSessionFactory1();

private static SessionFactory buildSessionFactory1() {
    Configuration configuration = new Configuration().configure(); // configuration
                                                                    // settings
                                                                    // from
                                                                    // hibernate.cfg.xml

    StandardServiceRegistryBuilder serviceRegistryBuilder = new StandardServiceRegistryBuilder();


    serviceRegistryBuilder.applySettings(configuration.getProperties());

    ServiceRegistry serviceRegistry = serviceRegistryBuilder.build();

    return configuration.buildSessionFactory(serviceRegistry);
}

public static SessionFactory getSessionFactory() {
    return sessionFactory;
}

public static void shutdown() {
    // Close caches and connection pools
    getSessionFactory().close();
}

}

Answer 3

I think for 4.3 it's now:

   Configuration configuration=new Configuration()
            .configure(); // configures settings from hibernate.cfg.xml

    StandardServiceRegistryBuilder serviceRegistryBuilder = new StandardServiceRegistryBuilder();

    // If you miss the below line then it will complaing about a missing dialect setting
    serviceRegistryBuilder.applySettings(configuration.getProperties());

    ServiceRegistry serviceRegistry = serviceRegistryBuilder.build();
    sessionFactory = configuration.buildSessionFactory(serviceRegistry);
