java - 寻找一个未弃用的 session 工厂

Question

我正在处理 hibernate ，当我打开当前项目时，我发现我的 Session-Factory 已被弃用:

AnnotationConfiguration af = new AnnotationConfiguration();
SessionFactory factory = af.configure().buildSessionFactory();
Session session = factory.openSession();

AnnotationConfiguration 现在似乎已被弃用...所以我检查了 JavaDoc，我被告知它已移至:

org.hibernate.cfg.Configuration

到目前为止，我的代码运行良好，实际上我不想更改它...但我搜索了一下，发现有人在问自己同样的问题，为什么 SessionFactory 需要更改... http://rgordon.co.uk/blog/2012/02/24/hibernate-please-dont-deprecate-yourself/

这篇文章来自 2012 年(所以不是那么旧......)并且以这种方式描述了所有内容:

ServiceRegistryBuilder serviceRegistryBuilder = new ServiceRegistryBuilder();
serviceRegistryBuilder.applySettings(properties);
ServiceRegistry serviceRegistry = serviceRegistryBuilder.buildServiceRegistry();

Configuration configuration = new Configuration().addClass(FeedTradePersistable.class);

SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);

我实现了。 JavaDoc 再次证明这是错误的!已弃用。 它指的是:

org.hibernate.boot.registry.StandardServiceRegistryBuilder

我又用谷歌搜索了一下。结果不太令人满意……

我开始修改代码...

ServiceRegistry serviceRegistry = serviceRegistryBuilder.build();
Configuration configuration = new Configuration();
SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);
Session session = sessionFactory.openSession();

然后抛出一个异常...

org.hibernate.HibernateException: Connection cannot be null when 'hibernate.dialect' not set

在线:

SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);

我很确定这是因为我没有指定任何配置设置。其实，我不想。我对 hibernate.cfg.xml 感到满意。

我试了一下 configuration.addFile(.. - 没那么成功...

有人知道吗？ 谢谢

更新:(hibernate.cfg.xml)

更新(2014 年 2 月 16 日): 我认为也有必要向您展示我的 pom.xml。我花了一段时间才弄清楚哪种 Hibernate-Framework 组合适合我...

Answer 1

我认为 4.3 现在是:

   Configuration configuration=new Configuration()
            .configure(); // configures settings from hibernate.cfg.xml

    StandardServiceRegistryBuilder serviceRegistryBuilder = new StandardServiceRegistryBuilder();

    // If you miss the below line then it will complaing about a missing dialect setting
    serviceRegistryBuilder.applySettings(configuration.getProperties());

    ServiceRegistry serviceRegistry = serviceRegistryBuilder.build();
    sessionFactory = configuration.buildSessionFactory(serviceRegistry);
