我正在尝试使用Spring框架使用JUnit测试CRUD方法.下面的代码完美无缺

 @Transactional
public class TestJdbcDaoImpl {
    @SuppressWarnings("deprecation")
    @BeforeClass 
    @Test
    public static void setUpBeforeClass() throws Exception {
        ApplicationContext ctx = new ClassPathXmlApplicationContext("spring.xml");
        JdbcDaoImpl dao = ctx.getBean("jdbcDaoImpl",JdbcDaoImpl.class);
        Circle cicle = new Circle();
        dao.insertCircle(new Circle(6,"e"));
    }}

但是,使用@RunWith(SpringJUnit4ClassRunner.class)的代码会给我一个错误

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/spring.xml")
@Transactional
public class TestJdbcDaoImpl {

   @Autowired
   private static JdbcDaoImpl dao;

   @SuppressWarnings("deprecation")
   @BeforeClass 
   public static void setUpBeforeClass() throws Exception {
       Circle cicle = new Circle();
       dao.insertCircle(new Circle(10,"e"));
   }
