如果有人更新到5.1，这是它是如何工作的

StandardServiceRegistry registry = new StandardServiceRegistryBuilder().configure().build();
                MetadataSources sources = new MetadataSources(registry);
                Metadata metadata = sources.getMetadataBuilder().build();
                sessionFactory = metadata.getSessionFactoryBuilder().build();

而不是hibernate 4.3中的下面

 ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(
            configuration.getProperties()). buildServiceRegistry();
    sessionFactory = configuration.buildSessionFactory(serviceRegistry);

如果你正在使用Hibernate 5.2及以上版本，那么你可以使用这个:

  private static StandardServiceRegistry registry;
  private static SessionFactory sessionFactory;

  public static SessionFactory getSessionFactory() {
    if (sessionFactory == null) {
      try {
        // Creating a registry
        registry = new StandardServiceRegistryBuilder().configure("hibernate.cfg.xml").build();

        // Create the MetadataSources
        MetadataSources sources = new MetadataSources(registry);

        // Create the Metadata
        Metadata metadata = sources.getMetadataBuilder().build();

        // Create SessionFactory
        sessionFactory = metadata.getSessionFactoryBuilder().build();

      } catch (Exception e) {
        e.printStackTrace();
        if (registry != null) {
          StandardServiceRegistryBuilder.destroy(registry);
        }
      }
    }
    return sessionFactory;
  }

  //To shut down
 public static void shutdown() {
    if (registry != null) {
      StandardServiceRegistryBuilder.destroy(registry);
    }
  }

公共无效sampleConnection()抛出异常{

     Configuration cfg = new Configuration().addResource("hibernate.cfg.xml").configure();
     StandardServiceRegistryBuilder ssrb = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
     SessionFactory sessionFactory = configuration.buildSessionFactory(ssrb.build());
     Session session = sessionFactory.openSession();
     logger.debug(" connection with the database created successfuly.");
}

在最新的hibernate 4.3.0版本中创建SessionFactory对象的更好方法如下:

Configuration configuration = new Configuration().configure();
StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().
applySettings(configuration.getProperties());
SessionFactory factory = configuration.buildSessionFactory(builder.build());

是的，它被弃用了。用下面的代码替换你的SessionFactory:

在Hibernate 4.0, 4.1, 4.2

private static SessionFactory sessionFactory;
private static ServiceRegistry serviceRegistry;

public static SessionFactory createSessionFactory() {
    Configuration configuration = new Configuration();
    configuration.configure();
    ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(
            configuration.getProperties()). buildServiceRegistry();
    sessionFactory = configuration.buildSessionFactory(serviceRegistry);
    return sessionFactory;
}

更新:

在Hibernate 4.3中，ServiceRegistryBuilder已弃用。请使用以下语句。

serviceRegistry = new StandardServiceRegistryBuilder().applySettings(
            configuration.getProperties()).build();

or

public class Hbutil {

    private static SessionFactory sessionFactory;
    private static ServiceRegistry serviceRegistry;

    private static SessionFactory configureSessionFactory() throws HibernateException {
        Configuration configuration = new Configuration();
        configuration.configure();
        serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();        
        sessionFactory = configuration.buildSessionFactory(serviceRegistry);
        return sessionFactory;
    }

    public static SessionFactory getSessionFactory() {
        return configureSessionFactory();

    }
}
