如何将id变量传递给具有依赖注入Symfony 3.4的类

namespace AppBundle\Service;

class MyService
{
    private $id;

    public function __construct($id)
    {
        $this->id = $id;
    }

    // ...
}

services:
    app.my_service:
        class: AppBundle\Service\MyService
        arguments:
            - '%my_id%'

parameters:
    my_id: 123

namespace AppBundle\Controller;

use AppBundle\Service\MyService;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;

class MyController extends Controller
{
    public function indexAction(MyService $myService)
    {
        $id = $myService->getId();

        // ...
    }
}
