Hibernate 4.1.0 Final：初始配置失败

Question

我正在从休眠 3.0 迁移到 4.1。 我有一个代码 sn-p 用于在我的应用程序中初始化休眠。

        ServiceRegistryBuilder srBuilder = new ServiceRegistryBuilder();
        srBuilder.configure();
        ServiceRegistry serviceRegistry = srBuilder.buildServiceRegistry();

        // Initializes the session factory.
        sessionConfiguration = new Configuration().configure();
        sessionFactory = sessionConfiguration.buildSessionFactory(serviceRegistry);
        sessionSettings = sessionConfiguration.buildSettings(serviceRegistry);

我在 srBuilder.confiugre() 处遇到异常。 异常堆栈跟踪： 尽管异常显示“超时”，但不确定这是什么意思：

如果您使用的是 Hibernate.cfg.xml，

你可以这样试试：

Configuration configuration = new Configuration().configure();
ServiceRegistryBuilder serviceRegistryBuilder = new ServiceRegistryBuilder();
serviceRegistryBuilder.applySettings(configuration.getProperties());
ServiceRegistry serviceRegistry = serviceRegistryBuilder.buildServiceRegistry();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
