关于Junit结合spring测试加载bean的问题

问题一：
public class text
{
private static final Logger logger = LoggerFactory.getLogger(text.class);
@Autowired
private NumBasicJob numBasicJob;
@Test
public void insert()
{
ApplicationContext act=new ClassPathXmlApplicationContext("spring.xml");
NumBasicJob p=(NumBasicJob) act.getBean("numBasicJob");
p.ExecuteOcfJob(text.class);
//numBasicJob.ExecuteOcfJob(text.class);
}
}
我代码全部使用注解，加载spring并没有报错，但是获取不到bean，也就是p为空，我认为可能是 ApplicationContext act=new ClassPathXmlApplicationContext("spring.xml
");不支持注解，不知道对不对？
问题2：
public class text extends BaseJunit4Test
{
private static final Logger logger = LoggerFactory.getLogger(text.class);
@Autowired
private NumBasicJob numBasicJob;
@Test
public void insert()
{
/* ApplicationContext act=new ClassPathXmlApplicationContext("spring.xml");
NumBasicJob p=(NumBasicJob) act.getBean("numBasicJob");
p.ExecuteOcfJob(text.class);*/
numBasicJob.ExecuteOcfJob(text.class);
}
}
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({
"classpath:spring.xml"
})
public class BaseJunit4Test {
private static final Logger LOG_RECORD=Logger.getLogger(OcfProductBasicJob.class);
@Before
public void init() {
//在运行测试之前的业务代码
LOG_RECORD.info("start to execute task," + new Date().toString());
}
@After
public void after() {
//在测试完成之后的业务代码
LOG_RECORD.info("end to execute task," + new Date().toString());
}
}
按道理说，我使用junit结合spring进行测试的时候，numBasicJob不应该为空，因为这个支持注解。
