Hibernate4测试报错，无法创建表

在用Hibernate4创建一张表，测试报错
报错代码：sessionFactory = configuration.buildSessionFactory(serviceRegistry);

以下是测试类

public class HibernateTest extends TestCase {
    private SessionFactory sessionFactory;
    private Session session;
    private Transaction transaction;

    @Override
    protected void setUp() throws Exception {
        // TODO Auto-generated method stub
        Configuration configuration = new Configuration().configure();
        ServiceRegistry serviceRegistry = 
                new ServiceRegistryBuilder().applySettings(configuration.getProperties())
                                            .buildServiceRegistry();
        sessionFactory = configuration.buildSessionFactory(serviceRegistry);

        session = sessionFactory.openSession();
        transaction = session.beginTransaction();
    }

    @Override
    protected void tearDown() throws Exception {
        // TODO Auto-generated method stub
        transaction.commit();
        session.close();
        sessionFactory.close();
    }

    public void testHib(){

    }
}
