如何在Symfony中将存储库注入服务？

Question

我需要将两个对象注入ImageService。其中一个是的实例Repository/ImageRepository，我得到这样的信息：

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

那么如何在我的services.yml中声明呢？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);
    }
}

我找到了此链接，这对我有用：

parameters:
    image_repository.class:            Mycompany\MainBundle\Repository\ImageRepository
    image_repository.factory_argument: 'MycompanyMainBundle:Image'
    image_manager.class:               Mycompany\MainBundle\Service\Image\ImageManager
    image_manipulator.class:           Mycompany\MainBundle\Service\Image\ImageManipulator

services:
    image_manager:
        class: %image_manager.class%
        arguments:
          - @image_manipulator
          - @image_repository

    image_repository:
        class:           %image_repository.class%
        factory_service: doctrine.odm.mongodb
        factory_method:  getRepository
        arguments:
            - %image_repository.factory_argument%

    image_manipulator:
        class: %image_manipulator.class%
