如何将存储库注入到 Symfony 中的服务中？

我需要将两个对象注入ImageService。其中一个例子是Repository/ImageRepository，我得到这样的：

$image_repository = $container->get('doctrine.odm.mongodb')
    ->getRepository('MycompanyMainBundle:Image');

那么我该如何在 services.yml 中声明这一点呢？这是服务：

namespace Mycompany\MainBundle\Service\Image;

use Doctrine\ODM\MongoDB\DocumentRepository;

class ImageManager {
    private $manipulator;
    private $repository;

    public function __construct(ImageManipulatorInterface $manipulator, DocumentRepository $repository) {
        $this->manipulator = $manipulator;
        $this->repository = $repository;
    }

    public function findAll() {
        return $this->repository->findAll();
    }

    public function createThumbnail(ImageInterface $image) {
        return $this->manipulator->resize($image->source(), 300, 200);
    }
}

对于像我这样来自 Google 的人来说，这是一个清理后的解决方案：

Update:这是 Symfony 2.6（及更高版本）的解决方案：

services:

    myrepository:
        class: Doctrine\ORM\EntityRepository
        factory: ["@doctrine.orm.entity_manager", getRepository]
        arguments:
            - MyBundle\Entity\MyClass

    myservice:
        class: MyBundle\Service\MyService
        arguments:
            - "@myrepository"

已弃用解决方案（Symfony 2.5 及更低版本）：

services:

    myrepository:
        class: Doctrine\ORM\EntityRepository
        factory_service: doctrine.orm.entity_manager
        factory_method: getRepository
        arguments:
            - MyBundle\Entity\MyClass

    myservice:
        class: MyBundle\Service\MyService
        arguments:
            - "@myrepository"
