我编辑了上面batbaatar创建的方法，使它接受Configuration对象作为参数:

    public static SessionFactory createSessionFactory(Configuration configuration) {
        serviceRegistry = new StandardServiceRegistryBuilder().applySettings(
                configuration.getProperties()).build();
        factory = configuration.buildSessionFactory(serviceRegistry);
        return factory;
    }

在主课程中，我做了:

    private static SessionFactory factory;
    private static Configuration configuration 
    ...      
    configuration = new Configuration();
    configuration.configure().addAnnotatedClass(Employee.class);
    // Other configurations, then           
    factory = createSessionFactory(configuration);

只需导入以下包，

import org.hibernate.cfg.Configuration;

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();

    }
}

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);

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();
 }

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());
