当我将Hibernate版本从3.6.8更新到4.0.0时，我在这一行中得到了关于已弃用方法buildSessionFactory()的警告:
private static final SessionFactory sessionFactory =
new Configuration().configure().buildSessionFactory();
Javadoc建议使用另一种方法
buildSessionFactory (ServiceRegistry ServiceRegistry)
但在文档中我发现了弃用的变体
当前回答
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);

Tested on 4.2.7 release
package com.national.software.hibernate;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;
import com.national.software.dto.UserDetails;
public class HibernateTest {
static SessionFactory sessionFactory;
public static void main(String[] args) {
// TODO Auto-generated method stub
UserDetails user = new UserDetails();
user.setUserId(1);
user.setUserName("user1");
Configuration config = new Configuration();
config.configure();
ServiceRegistry serviceRegistry = (ServiceRegistry) new ServiceRegistryBuilder().applySettings(config.getProperties()).buildServiceRegistry();
sessionFactory = config.buildSessionFactory(serviceRegistry);
Session session = sessionFactory.openSession();
session.beginTransaction();
session.save(user);
session.getTransaction().commit();
}
}
如果有人更新到5.1，这是它是如何工作的

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。
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);
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);
