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

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);
其他回答
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 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();
}
}
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();
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();
}
}
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)。
