Symfony2/FOSUserBundle-登录后根据角色重定向

我想根据用户的角色自定义登录后的重定向。

仅供参考：我使用symfony 2.8

我创建了这个类：

<?php
namespace Users'UsersBundle'Redirection;
use Symfony'Component'Security'Http'Authentication'AuthenticationSuccessHandlerInterface;
use Symfony'Component'Security'Core'Authentication'Token'TokenInterface;
use Symfony'Component'Security'Core'Security;
use Symfony'Component'HttpFoundation'Request;
use Symfony'Component'HttpFoundation'RedirectResponse;
use Symfony'Component'Routing'RouterInterface;
class AfterLoginRedirection implements AuthenticationSuccessHandlerInterface
{
    protected $router;
    protected $security;
  /**
   * AfterLoginRedirection constructor.
   * @param Router $router
   * @param Security $security
  */
   public function __construct(Router $router, Security $security)
  {
    $this->router = $router;
    $this->security = $security;
  }
    /**
     * @param Request $request
     * @param TokenInterface $token
     * @return RedirectResponse
     */
     public function onAuthenticationSuccess(Request $request, TokenInterface $token)
  {
    if ($this->security->isGranted('ROLE_SUPER_ADMIN')) {
        $response = new RedirectResponse($this->router->generate('_homepage_admin'));
    } else {
        $referer_url = $request->headers->get('referer');
        $response = new RedirectResponse($referer_url);
    }
    return $response;
 }
}

我创建此服务：

services:
redirect.after.login:
    class: Users'UsersBundle'Redirection'AfterLoginRedirection
    arguments: [@router]

我修改了防火墙

    firewalls:
    main:
        pattern: ^/
        form_login:
            login_path: fos_user_security_login
            check_path: fos_user_security_check
            provider: fos_userbundle
            csrf_provider: form.csrf_provider
            success_handler: redirect.after.login
        logout:
            path:   /users/logout
            target: /
        anonymous:    true

我得到了这个错误：

可捕获的致命错误：参数1传递给Users''UsersBundle''Redirection''AfterLoginDirection:：__construct（）必须是Users''UsersBundle''Redirection''Router的实例，实例的Symfony''Bundle''FrameworkBundle''Routing''Router，在中调用C： 上的''wamp''www''eCommerce''app''cache''dev''appDevDebugProjectContainer.php2060行和定义的

我错过了什么？有什么线索或建议吗？

谢谢。
