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。

在hibernate 5.3.1中，你可以这样做:

ServiceRegistry standardRegistry = 
                new StandardServiceRegistryBuilder().configure().build();

Metadata sources = new MetadataSources(standardRegistry).addAnnotatedClass(MyEntity.class).getMetadataBuilder().build();

SessionFactory sf = sources.buildSessionFactory();

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.");
}

是的，它被弃用了。http://docs.jboss.org/hibernate/core/4.0/javadocs/org/hibernate/cfg/Configuration.html#buildSessionFactory()特别告诉您使用您找到的另一个方法(buildSessionFactory(ServiceRegistry ServiceRegistry))—因此使用它。

文档从一个版本复制到另一个版本，可能只是还没有更新(他们不会在每个版本都重写手册)——所以请相信Javadocs。

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();

    }
}
