Symfony 4.1，sonata Admin不会被覆盖

Question

I wanted to override editAction method of Sonata Admin. I created an admin class and extended it from Sonata\\AdminBundle\\Controller\\CRUDController then I wrote editAction with my personal edit but when I access the edit post page, the old Sonata editAction gets called and not my function! here is my admin class:

    <?php
namespace App\Controller;

use Sonata\AdminBundle\Controller\CRUDController as Controller;
use Symfony\Component\HttpFoundation\RedirectResponse;
use App\Manager\SiteManagerInterface;
use App\Manager\UserManagerInterface;
use App\Entity\Site;
use App\Entity\Profile;
use App\Entity\User;
use App\Entity\Payment;
use Symfony\Component\HttpFoundation\Response;

class UserAdminCRUDController extends Controller
{
    /** @var SiteManagerInterface $siteManager */
    private $siteManager;


    public function editAction($id = null)
    {
        return new Response("test");
    }

}

I believe that you forgot to register the action service. You can do it by: Either by using XML:

<!-- src/Resources/config/admin.xml -->

<service id="app.admin.car" class="App\Admin\CarAdmin">
    <tag name="sonata.admin" manager_type="orm" group="Demo" label="Car" />
    <argument />
    <argument>App\Entity\Car</argument>
    <argument>App\Controller\CRUDController</argument>
</service>

or in an yml

# src/Resources/config/admin.yml
services:
    app.admin.car:
        class: App\Admin\CarAdmin
        tags:
            - { name: sonata.admin, manager_type: orm, group: Demo, label: Car }
        arguments:
            - null
            - App\Entity\Car
            - App\Controller\CRUDController
        public: true
