如何在Symfony中将存储库注入服务?

问题描述

我需要将两个对象注入到ImageService中.其中之一是Repository/ImageRepository的实例，我得到的像这样:

I need to inject two objects into ImageService. One of them is an instance of Repository/ImageRepository, which I get like this:

$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:

So how do I declare that in my services.yml? Here is the service:

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);
    }
}

推荐答案

我发现了这个 link ，这对我有用:

I found this link and this worked for me:

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%
