spring mvc注解不能访问到controller,是什么原因？

web.xml配置

<servlet>  
<servlet-name>annomvc</servlet-name>  
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>   
<init-param>    
<param-name>contextConfigLocation</param-name>    
<param-value>/WEB-INF/annomvc-servlet.xml</param-value>   
</init-param>   
<load-on-startup>2</load-on-startup> 
</servlet> 
<servlet-mapping>   
<servlet-name>annomvc</servlet-name>   
<url-pattern>*.do</url-pattern> 
</servlet-mapping>

annomvc-servlet.xml配置

页面请求

<form method="post" action="userlogin.do?method=login" >




<context:annotation-config />    
    <!-- 把标记了@Controller注解的类转换为bean -->            
    <context:component-scan base-package="com.svs.master.controller" />

   <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->    
  <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />     

   <!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->     
   <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"     
      p:prefix="/csy/page/" p:suffix=".htm" />
   <bean id="multipartResolver"     
      class="org.springframework.web.multipart.commons.CommonsMultipartResolver"     
      p:defaultEncoding="utf-8" />
