springmvc 整合 shiro 无法访问控制器 404问题

<aop:config proxy-target-class="true"/>     
<!--<aop:aspectj-autoproxy />-->    
<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
<property name="securityManager" ref="securityManager"/>    
</bean>

这是springmvc.xml的配置,applicationContext.xml的配置如下

<bean id="credentialsMatcher" class="org.apache.shiro.authc.credential.HashedCredentialsMatcher">           
 <property name="hashAlgorithmName" value="md5"/>   
 <property name="hashIterations" value="2"/>
</bean>     <!-- 自定义realm -->
<bean id="shiroDbRealm" class="cn.ddsxy.ddlx.shiro.ShiroDbRealm">
<property name="credentialsMatcher" ref="credentialsMatcher"/>
</bean>     
<!-- 安全管理器 -->
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="realm" ref="shiroDbRealm"/>
</bean>     
<!-- 基于Form表单的身份验证过滤器 -->
<bean id="formAuthenticationFilter" class="org.apache.shiro.web.filter.authc.FormAuthenticationFilter">
<property name="usernameParam" value="username"/>
<property name="passwordParam" value="password"/>
<property name="loginUrl" value="/login"/>
</bean> 
<!-- Shiro的Web过滤器 -->
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<property name="securityManager" ref="securityManager"/>
<property name="loginUrl" value="/login"/>
<property name="unauthorizedUrl" value="/403"/>
<property name="filters">
<map>
<entry key="authc" value-ref="formAuthenticationFilter"/>
</map>
</property>
<property name="filterChainDefinitions">
<value> /** = anon</value>
</property>
</bean>     
<!-- 保证实现了Shiro内部lifecycle函数的bean执行 -->
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/> <aop:config proxy-target-class="true"/>
