Question

方法getSubscribedServices似乎没有注入我的依赖关系。当我尝试将其与本地别名registry一起使用时，它表示未找到该服务；有人会知道我在想什么吗？

class UserService implements ServiceSubscriberInterface
{

protected $container;
protected $session;

public function __construct(ContainerInterface $container)
{
    $this->container = $container;
    $this->session = new Session();
}

public static function getSubscribedServices()
{
    return [
        'registry' => ManagerRegistry::class
    ];
}

呼叫$this->container->get('registry')失败，并显示错误消息

You have requested a non-existent service "registry".

服务

App\Controller\userMgmt\UserService:
    lazy: true

usermgmt:
    alias: App\Controller\userMgmt\UserService

找不到Symfony 4订阅的服务注入
