symfony - "Service xxx has a dependency on a non-existent service"这似乎不是真的？

Question

我有一些应用程序要迁移到 Symfony 4.1。启用后 container.autowiring.strict_mode: true我在维护我们的自定义时出错 Router

The service ".service_locator.G69Xsbl.Foo\Bundle\Admin\SiteRoutingBundle\Routing\AdminSiteRouter" 
has a dependency on a non-existent service "Symfony\Component\Config\Loader\LoaderInterface".

该类看起来像:

<?php

namespace Foo\Bundle\Admin\SiteRoutingBundle\Routing;

use Symfony\Bundle\FrameworkBundle\Routing\Router;
use Foo\Bundle\Common\CoreBundle\Manager\SiteManagerInterface;

class AdminSiteRouter extends Router
{
    const USE_SITE_HOST  = true;
    const USE_SITE_PARAM = false;

    protected $siteManager;

    public function setSiteManager(SiteManagerInterface $siteManager)
    {
        $this->siteManager = $siteManager;
    }

    public function generate($name, $parameters = [], $referenceType = self::ABSOLUTE_URL)
    {
        // some code
    }
}

既不在这个类(class)，也不在扩展类(class) Router来自 FrameworkBundle 的依赖于 LoaderInterface .

此类的 Autowiring 配置:

Foo\Bundle\Admin\SiteRoutingBundle\Routing\AdminSiteRouter:
    arguments:
        $resource: '%site_routing_file_path%'
        $options: []
    calls:
        - [setSiteManager, ['@Foo\Bundle\Common\CoreBundle\Manager\SiteManagerInterface']]

看起来有两个容器参数导致了问题。使用全新的 4.1.1 安装我遇到了同样的错误。修复它:

# services.yaml
App\Service\AdminRouter:
    arguments:
        $container: '@service_container'
        $parameters: '@service_container'
        $resource: 'resource'
        $options: []

我的管理路由器很简单:

namespace App\Service;
use Symfony\Bundle\FrameworkBundle\Routing\Router;
class AdminRouter extends Router
{
}

作为引用，框架路由器如下所示:

public function __construct(
    ContainerInterface $container, 
    $resource, 
    array $options = array(), 
    RequestContext $context = null, 
    ContainerInterface $parameters = null, 
    LoggerInterface $logger = null)
{

注意两个 ContainerInterface 参数。我认为这是令人困惑的 Autowiring 。甚至可能是一个错误。
