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());

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();

在Hibernate 4.2.2中

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;

public class Test {
    public static void main(String[] args) throws Exception
{
    Configuration configuration = new Configuration()
            .configure();

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

    SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);

    Session session = sessionFactory.openSession();

    Transaction transaction = session.beginTransaction();

    Users users = new Users();

    ... ...

    session.save(users);

    transaction.commit();

    session.close();

    sessionFactory.close();

    }
}

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);

代码已验证可在Hibernate 4.3.0中工作。注意，您可以删除XML文件名参数，或者提供您自己的路径。这与这里的其他帖子类似(但错别字更正了)，但这一篇是正确的。

import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;    


Configuration configuration = new Configuration();
configuration.configure("/com/rtw/test/hiber/hibernate.cfg.xml");
ServiceRegistry  serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();        
    sessionFactory = configuration.buildSessionFactory(serviceRegistry);
