在JUnit测试中自动装配Spring服务

Question

我有以下Spring服务:

@Service
public class MyService  {
   public List<int> getIds(Filter filter){
      ...
   }
}

和配置类:

@Configuration
public static class MyApplicationContext {

    @Bean
    public Filter filter(ApplicationContext context) {
        return new Filter();
    }
}

现在,我想创建一个单元测试来检查getIds方法是否返回正确的结果.我创建了以下JUnit测试:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes=MyApplicationContext.class,                                                   
                      loader=AnnotationConfigContextLoader.class)
public class AppTest
{
    @Autowired
    Filter filter;

    @Autowired
    MyService service;
}

编译器为Filter类找到正确的bean,但是为服务变量抛出"BeanCreationException:Could not autowire field"异常.我尝试将服务类添加到ContextConfiguration.classes,但随后编译器抛出"IllegalStateException:无法加载ApplicationContext"异常.

如何在ContextConfiguration中包含MyService？

MyApplicationContext为要扫描的服务添加以下注释@ComponentScan("myservice.package.name")
