我一直收到一条消息：“org.springframework.beans.factory.NoSuchBeanDefinitionException：没有定义名为’userDetailsS​​ervice’的bean”,即使bean被定义为UserDetailsS​​erviceImpl类中的服务.如：

@Service(value="userDetailsService")
public class UserDetailsServiceImpl implements UserDetailsService{

我正在使用最新的Spring和Spring Security.

我不确定我做错了什么.我正在粘贴我的spring xml文件的配置. spring-security.xml显示它在使用组件扫描时可以从servlet-context.xml中找到bean.

谢谢
