将JUnitJPA测试从Spring2.5.5迁移到Spring3.0.4

我们的项目刚刚决定从Spring2.5.5迁移到Spring3.0.4。在我的原始代码中，我有如下的单元测试：

public class RequisitionDaoTest extends AbstractJpaTests
{

    public static String FAIL_MSG_UNEXPECTED_ERROR = "FAIL: Unexpected Error";

        @PersistenceContext
        private EntityManager em;

    @PersistenceUnit
    private EntityManagerFactory emf;

        @Test
        public void testSomething ()
        {
          ...
        }
}

这在Spring2.5.5中运行得很好。现在在Spring3.0.4中，AbstractJpaTests类已被弃用

问题是我似乎找不到用什么来代替它。我看过几篇文章显示使用了一种叫做AbstractTransactionalJUnit4SpringContextTests的东西，但是当我转换为使用它时，我得到了以下错误：
