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());

这里有很多hibernate核心框架中已弃用的api。

我们已经创建了会话工厂，如下所示:

SessionFactory SessionFactory = new Configuration().configure(). buildessionfactory ();

方法buildSessionFactory在hibernate 4发行版中已弃用，并被新的API所取代。如果你使用hibernate 4.3.0及以上版本，你的代码必须是:

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

从4.3.0开始，类ServiceRegistryBuilder被StandardServiceRegistryBuilder取代。看起来在5.0版本中会有很多变化。但是，对于已弃用的api和适合使用的替代方案仍然没有太多的明确说明。每一个增量版本都会出现更多弃用的API，它们都是为了5.0版本的核心框架进行微调。

道理很简单:JBoss文档并不是100%维护得很好。按照JavaDoc的说法:buildSessionFactory(ServiceRegistry ServiceRegistry)。

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());

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);

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();

    }
}
