You can use a Doctrine entity listener/subscriber instead and to inject the security token and gets the current user logged:

// src/AppBundle/EventListener/EntityListener.php
namespace AppBundle\EventListener;

use Doctrine\ORM\Event\LifecycleEventArgs;
use AppBundle\Entity\GenericEntity;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;

class EntityListener
{
    private $tokenStorage;

    public function __construct(TokenStorageInterface $tokenStorage = null) 
    {
        $this->tokenStorage = $tokenStorage;
    }

    public function prePersist(LifecycleEventArgs $args)
    {
        $entity = $args->getEntity();

        // only act on some "GenericEntity" entity
        if (!$entity instanceof GenericEntity) {
            return;
        }

        if (null !== $currentUser = $this->getUser()) {
            $entity->setCreationId($currentUser->getId());
        } else {
            $entity->setCreationId(0);
        }
    }

    public function getUser()
    {
        if (!$this->tokenStorage) {
            throw new \LogicException('The SecurityBundle is not registered in your application.');
        }

        if (null === $token = $this->tokenStorage->getToken()) {
            return;
        }

        if (!is_object($user = $token->getUser())) {
            // e.g. anonymous authentication
            return;
        }

        return $user;
    }
}

Next register you listener:

# app/config/services.yml
services:
    my.listener:
        class: AppBundle\EventListener\EntityListener
        arguments: ['@security.token_storage']
        tags:
            - { name: doctrine.event_listener, event: prePersist }

Answer 2

You can look at BlameableListener from gedmo/doctrine-extensions package, that work almost the way you want but with the username instead of the user id.

Answer 3

@ORM\PrePersist and other callback methods used in the entity are suppose to contain simple logic and be independant of other services.

You need to create event listener or subscriber to listen postPersist doctrine event and fill in corresponding attribute. Check How to Register Event Listeners and Subscribers
