在不同版本的文档之间发现差异并不罕见。大多数开发人员认为文档是一件苦差事，他们倾向于推迟它。

根据经验，如果javadoc说了一件事，而一些非javadoc的文档与之相矛盾，那么javadoc很可能更准确。程序员更倾向于让javadoc与代码的变化保持同步…因为javadoc的“源代码”与代码在同一个文件中。

在@deprecated标记的情况下，javadoc几乎肯定更准确。开发人员经过仔细考虑后反对使用……而且(一般来说)他们不会对它们进行undeprecated。

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();
 }

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();

    }
}

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();

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);

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());
