Shiro Annotations on a jersey resource

when I am using shiro to do @RequiresAuthorization on a jersey resource i'm getting the following exception:

org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'securedFileResourceImpl' must be of type [org.apache.shiro.samples.sprhib.web.resources.SecuredFileResourceImpl], but was actually of type [$Proxy81]

I can get rid of this by doing the following

<bean class="org.apache.shiro.samples.sprhib.web.resources.SecuredFileResourceImpl" id="securedFileResource">
        <aop:scoped-proxy proxy-target-class="true"/>
    </bean>

but

<aop:config proxy-target-class="true"/>

does not work

Got it working with the following config

< !-- Required for security annotations to work in this servlet -- >
    <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor">
        <property name="proxyTargetClass" value="true" />
    </bean>

    <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
        <property name="securityManager" ref="securityManager" />
    </bean>

    <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
        <property name="realm" ref="vendorRealm" />
    </bean>

    <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor" />
