CheckProfile.php

<?php

namespace App\Controller;

use App\Event\CheckProfileListener;
use Cake\Event\Event;
/**
 * CheckProfile trait
 */
trait CheckProfile {

    public function beforeFilter(Event $event) {
        parent::beforeFilter($event);
        $this->eventManager()->on(new CheckProfileListener($this->Auth));
    }

}

<?php

namespace App\Controller;

/**
 * CheckProfile trait
 */
trait CheckProfileTrait {

    public function implementedEvents() {
        return ['Controller.beforeFilter' => 'myBeforeFilter'];
    }

    public function myBeforeFilter() {
        throw new \Cake\Network\Exception\NotFoundException('hahaha');
    }

}

And

<?php

namespace App\Controller\Admin;

use App\Controller\AppController;
use App\Controller\CheckProfileTrait;
use Cake\Event\EventListenerInterface;

/**
 * Dashboard Controller
 *
 * @property \App\Model\Table\DashboardTable $Dashboard
 */
class DashboardController extends AppController implements EventListenerInterface {

    use CheckProfileTrait;

    /**
     * Index method
     *
     * @return void
     */
    public function index() {

    }

}

But cannot throw Exception
