Hibernate 4.3.0.Final获取会话

Question

在hibernate 4.3.0.Final文档中，给出了以下代码片段来创建SessionFactory:

package org.hibernate.tutorial.util;

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class HibernateUtil {

    private static final SessionFactory sessionFactory = buildSessionFactory();

    private static SessionFactory buildSessionFactory() {
        try {
            // Create the SessionFactory from hibernate.cfg.xml
            return new Configuration().configure().buildSessionFactory();
        }
        catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            throw new ExceptionInInitializerError(ex);
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }

}

这似乎已经过时了，因为方法 buildSessionFactory() 已经被弃用。创建 SessionFactory 的正确方式是什么？

public class TestHB4 {
    private static StandardServiceRegistry serviceRegistry;
    private static SessionFactory sessionFactory;

    public static void main(String[] args) {
        Person person = new Person();
        person.setFirstName("Namal");
        person.setLastName("Dinesh");


        Configuration configuration = new Configuration().configure();
        serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
        sessionFactory = configuration.configure().buildSessionFactory(serviceRegistry);

        Session session = sessionFactory.openSession();

        session.beginTransaction();

        session.save(person);

        session.getTransaction().commit();
        session.close();


    }

你能否也看一下我的问题：https://dev59.com/Un_aa4cB1Zd3GeqP6Ku3。 - Jack

谢谢！（我想知道他们什么时候会决定停止更改这个） - Ordiel

在这个答案中，Configuration.configure() 被调用了两次。 我认为这可能会导致抛出像 Duplicate class/entity mapping 这样的异常，因为配置被解析了两次。我认为代码的第10行应该更改为 sessionFactory = configuration.buildSessionFactory(serviceRegistry);。如果我错了，请纠正我。 - prageeth
