maven项目下使用context:component-scan的困惑

我搭建了一个java maven项目，在运行test文件下的类时，需要扫描main下的一个文件夹下的标记了@Component的类，但是在测试类使用@Autowired时报无法装配的错误：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.liu.core.workflow.WrokflowTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.liu.core.workflow.service.WorkFlowService com.liu.core.workflow.WrokflowTest.workflowService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.liu.core.workflow.service.WorkFlowService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

context:component-scan是来指定扫描哪个包下的bean，http://blog.csdn.net/chunqiuwei/article/details/16115135
