Question

这是我的简单测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath*:root-context.xml")
public class ServiceTest {


    @Autowired
    private CafeService cafeDataService;


    @Test
    public void testCafeService()
    {
        assertTrue(cafeDataService.get()!=null);
    }
}

我的root-context.xml：

<context:component-scan base-package="ru.tenet.cafe" />

<mvc:resources mapping="/resources/**" location="/resources/" />

这就是我所拥有的：

创建名为'ru.tenet.cafe.ServiceTest'的bean时出错：注入自动连接的依赖关系失败;嵌套异常是 org.springframework.beans.factory.BeanCreationException：不能 autowire字段：private ru.tenet.cafe.service.CafeService ru.tenet.cafe.ServiceTest.cafeDataService;嵌套异常是 org.springframework.beans.factory.NoSuchBeanDefinitionException：没有找到类型为[ru.tenet.cafe.service.CafeService]的限定bean 依赖：预计至少有1个bean有资格成为autowire 这种依赖的候选人。依赖注释： {@ org.springframework.beans.factory.annotation.Autowired（所需=真）}

有什么问题？我可以在控制器内自动提供服务，但我的测试不允许我这样做。

无法在junit测试中自动装配bean
