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。

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();

如果你正在使用Hibernate 5.2及以上版本，那么你可以使用这个:

  private static StandardServiceRegistry registry;
  private static SessionFactory sessionFactory;

  public static SessionFactory getSessionFactory() {
    if (sessionFactory == null) {
      try {
        // Creating a registry
        registry = new StandardServiceRegistryBuilder().configure("hibernate.cfg.xml").build();

        // Create the MetadataSources
        MetadataSources sources = new MetadataSources(registry);

        // Create the Metadata
        Metadata metadata = sources.getMetadataBuilder().build();

        // Create SessionFactory
        sessionFactory = metadata.getSessionFactoryBuilder().build();

      } catch (Exception e) {
        e.printStackTrace();
        if (registry != null) {
          StandardServiceRegistryBuilder.destroy(registry);
        }
      }
    }
    return sessionFactory;
  }

  //To shut down
 public static void shutdown() {
    if (registry != null) {
      StandardServiceRegistryBuilder.destroy(registry);
    }
  }

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();

    }
}

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();

    }
}

只需导入以下包，

import org.hibernate.cfg.Configuration;
