无法加载ApplicationContext以JUnit测试和Spring

我想测试我使用的服务的JUnit，我越来越喜欢Failed to load ApplicationContext一些错误我试图加载使用@ContextConfiguration(loader = AnnotationConfigWebContextLoader.class, classes={MvcConfiguration.class})。我不停地经营业务类和Spring配置类src/main/java文件夹春天配置类和在src/test/java文件夹我的测试类，甚至我试图把MvcConfiguratio n个等级中src/test/java文件夹以及，但它没有工作，显示了同样的问题再次无法加载ApplicationContext以JUnit测试和Spring

这是我的测试类

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(loader = AnnotationConfigWebContextLoader.class, 
classes={MvcConfiguration.class}) 
public class ServiceTest { 
    @Autowired 
    private EmployeeService empService; 
    @Test 
    public void test() { 
     assertEquals(21, empService.employeeCount()); 
    } 
    @BeforeClass 
    public static void serviceIntaciation(){ 
     System.out.println("beforeclass"); 
    } 

}
