Shiro与权限注释不起作用

Question

现在，我可以正确检查java代码的权限（如下所示）：

subject.isPermitted("queryPrinter")

但如果我在注释中进行注释，它就会失败。

@ResponseBody
@RequiresPermissions("test::home")
@RequiresAuthentication
@RequestMapping(value = "/test/permission", method = RequestMethod.POST)
public Object testPermission() {
    return PdMDMResultUtil.createSuccess();
}

这是我在applicationContext-shiro.xml中的shiro配置

<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
    <property name="securityManager" ref="securityManager"/>
    <property name="loginUrl" value="${sso.server.url}"/>
    <property name="successUrl" value="${upms.successUrl}"/>
    <property name="unauthorizedUrl" value="${upms.unauthorizedUrl}"/>
    <property name="filters">
        <util:map>
            <entry key="authc" value-ref="upmsAuthenticationFilter"/>
            <entry key="permission" value-ref="upmsPermissionsAuthorizationFilter"/>
        </util:map>
    </property>
    <property name="filterChainDefinitions">
        <value>
            /sso/login = anon
            /sso/logout = upmsSessionForceLogout
            /sso/** = authc,permission
            /** = anon
        </value>
    </property>
</bean>

<bean id="upmsPermissionsAuthorizationFilter"
      class="im.pudong.mdm.client.shiro.filter.UpmsPermissionsAuthorizationFilter"/>
<bean id="upmsAuthenticationFilter" class="im.pudong.mdm.client.shiro.filter.UpmsAuthenticationFilter"/>
<bean id="upmsSessionForceLogout" class="im.pudong.mdm.client.shiro.filter.UpmsSessionForceLogoutFilter"/>

当我调试问题时，我发现debug screenshot pic。它显示了mappedValue

NULL ，但我预计 NOT NULL 。为什么？

public class UpmsPermissionsAuthorizationFilter extends PermissionsAuthorizationFilter {

@Override
public boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue) throws IOException {
    return super.isAccessAllowed(request, response, mappedValue);
}

}
