如何使用Symfony中的FosUserBundle将用户管理器作为服务访问？

composer require friendsofsymfony/user-bundle

return [
    // ...
    FOS\UserBundle\FOSUserBundle::class => ['all' => true],
];

fos_user:
    db_driver: orm
    firewall_name: main
    user_class: App\Entity\User
    service:
        user_manager: fos_user.user_manager.default

services:
    # ...
    App\Service\UserManager:
        arguments:
            $userManager: '@fos_user.user_manager.default'

namespace App\Service;

use FOS\UserBundle\Model\UserManagerInterface;

class UserManager
{
    private $userManager;

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

    // 在这里添加自定义方法，以便通过用户管理器服务访问
}

namespace App\Controller;

use App\Service\UserManager;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

class UserController extends AbstractController
{
    /**
     * @Route("/users")
     */
    public function index(UserManager $userManager): Response
    {
        $users = $userManager->findUsers();

        // ...
    }
}
