我正在嘗試實現多個控制器來監聽一個路由/account。有兩個控制器，并且只有一個應該在選擇位于用戶角色范圍內的 URL 上執行。namespace AppBundle\Controller;use AppBundle\Entity\Role;use Symfony\Bundle\FrameworkBundle\Controller\Controller;use Symfony\Component\Routing\Annotation\Route;/** * @Route("/account") */abstract class DashboardController extends Controller{    protected $userRoles;    public function __construct()    {        $this->userRoles = $this->getUser()->getRoles();    }    /**     * Get all user roles     */    public function getRoles()    {        return $this->userRoles;    }    /**     * Get user account type     *     * @return Role     */    public function getAccountType(): Role    {        $accountType = new Role();        foreach ($this->userRoles as $role) {            if(Role::ROLE_STUDENT == $role->getName()) {                $accountType = $role;            } else if(Role::ROLE_SCHOOL_REPRESENTATIVE == $role->getName()) {                $accountType = $role;            } else if(Role::ROLE_EMPLOYER == $role->getName()) {                $accountType = $role;            } else if(Role::ROLE_ADMIN == $role->getName()) {                $accountType = $role;            }        }        return $accountType;    }}namespace AppBundle\Controller;class CompanyDashboardController extends DashboardController{    public function __construct()    {        parent::__construct();    }    /**     * @Route("/", name="dashboard_company_home", methods={"GET"})     * @return Response     */    public function index()    {        return $this->render('dashboard/company/index.html.twig');    }}namespace AppBundle\Controller;class AdminDashboardController extends DashboardController{    public function __construct()    {        parent::__construct();    }    /**     * @Route("/", name="dashboard_admin_home", methods={"GET"})     * @return Response     */    public function index()    {        return $this->render('dashboard/admin/index.html.twig');    }}這就是我到目前為止所得到的。
