hibernate 5.x创建SessionFactory

权当笔记用的。。。

    private SessionFactory sessionFactory;
    @Before
    public void init() {
        // 创建服务注册对象
        final ServiceRegistry registry = 
                new StandardServiceRegistryBuilder().configure().build();
        try {
            // 创建会话工厂
            sessionFactory = 
                    new MetadataSources(registry).buildMetadata().buildSessionFactory();
        } catch(Exception ex) {
            ex.printStackTrace();
            StandardServiceRegistryBuilder.destroy( registry );
        }
    }
