这是我使用的文件:

component.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

    <context:component-scan

</beans>

ServiceImpl.java

@org.springframework.stereotype.Service
public class ServiceImpl implements MyService {

    @Autowired
    private MyDAO myDAO;

    public void getData() {...}    
}

ServiceImplTest.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath*:conf/components.xml")
public class ServiceImplTest{

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

错误:
