spring mvc注入service报错;

部分代码如下：

报错:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private myforum.service.UserTest myforum.controller.UserController.userTest; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [myforum.service.UserTest] 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)}
配置如下：
web.xml
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value>
</context-param>
<servlet>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>

</servlet>
<servlet-mapping>
<servlet-name>springMvc</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
spring.xml
<!-- 自动扫描dao和service包(自动注入) -->
<context:component-scan base-package="myforum.dao,myforum.service" />
<!-- 引入属性文件 -->
<context:property-placeholder location="classpath:config.properties" />
spring-mvc.xml
<!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 -->
<context:component-scan base-package="myforum.controller" />

需要的都提供了 应该没错，就是注入错误。求牛人解答
问题搞定了，谢谢大家。
还是不够火候，知道问题所在，却就是没发现这么个漏掉的
