Symfony 3.3 将存储库注入服务

Question

我有一个包保存在私有 Satis 存储库中，因为它的实体和存储库在多个应用程序之间共享。

使用该捆绑包的其余应用程序是 Symfony 2.7 和 2.8 应用程序。我正在开发一个新应用程序，要求是使用 Symfony 3.3。

在 symfony 3.3 应用程序中，我已经在 services.yml:

中尝试过这个

# Learn more about services, parameters and containers at
# http://symfony.com/doc/current/service_container.html
parameters:
    #parameter_name: value

services:
# default configuration for services in *this* file
    _defaults:
        autowire: true
        autoconfigure: true
        # this means you cannot fetch services directly from the container via $container->get()
        # if you need to do this, you can override this setting on individual services
        public: false

    # makes classes in src/AppBundle available to be used as services
    # this creates a service per class whose id is the fully-qualified class name
    CbmLtd\UvmsBundle\:
        resource: '../../vendor/cbmltd/uvms-bundle/*'
        exclude: '../../vendor/cbmltd/uvms-bundle/{Entity,Repository}'

    UvmsApiV1Bundle\:
        resource: '../../src/UvmsApiV1Bundle/*'
        exclude: '../../src/UvmsApiV1Bundle/{Entity,Repository}'

以上给出了以下异常：

Cannot autowire service "UvmsApiV1Bundle\Service\DealerService": argument "$repository" of method "__construct()" references class "CbmLtd\UvmsBundle\Repository\DealerRepository" but no such service exists. It cannot be auto-registered because it is from a different root namespace.

好的，所以我想我需要将此存储库显式声明为服务。我在 Symfony 3.3 文档中找不到任何关于将存储库声明为服务的内容，而且 2.8 语法也不起作用。

我将此添加到我的 services.yml:

services:
    ...
    CbmLtd\UvmsBundle\DealerRepository:
        class: CbmLtd\UvmsBundle\Entity\DealerRepository
        factory_service: doctrine.orm.entity_manager
        factory_method: getRepository
        arguments:
            - CbmLtd\UvmsBundle\Entity\Dealer

但我仍然遇到这个异常：

Cannot autowire service "UvmsApiV1Bundle\Service\DealerService": argument "$repository" of method "__construct()" references class "CbmLtd\UvmsBundle\Repository\DealerRepository" but no such service exists. It cannot be auto-registered because it is from a different root namespace.

我无法对 CbmLtd\UvmsBundle 进行任何更改，因为它被多个应用程序使用。任何帮助，将不胜感激。我真的花了几个小时在这上面，这很令人沮丧。

Answer 1

我能够使用以下 services.yml:

services:
# default configuration for services in *this* file
    _defaults:
        autowire: true
        autoconfigure: true

    # this means you cannot fetch services directly from the container via $container->get()
    # if you need to do this, you can override this setting on individual services
    public: false

    # makes classes in src/AppBundle available to be used as services
    # this creates a service per class whose id is the fully-qualified class name
    CbmLtd\UvmsBundle\:
        resource: '../../vendor/cbmltd/uvms-bundle/*'
        exclude: '../../vendor/cbmltd/uvms-bundle/{Entity,Repository}'

    CbmLtd\UvmsBundle\Repository\DealerRepository:
        factory: doctrine.orm.entity_manager:getRepository
        arguments:
            - CbmLtd\UvmsBundle\Entity\Dealer

    UvmsApiV1Bundle\:
        resource: '../../src/UvmsApiV1Bundle/*'
        exclude: '../../src/UvmsApiV1Bundle/{Entity,Repository}'

我不得不稍微更改一下我的控制器，但它现在可以正常工作了。

尝试更改您的存储库服务声明

your_bundle.your_entity_repository:
    class: Doctrine\ORM\EntityRepository
    factory: ['@doctrine.orm.default_entity_manager', getRepository]
    arguments:
        - YourBundle\Entity\YourEntity

然后通过像这样引用它来注入回购：

your_bundle.your_service:
    class: YourBundle\Service\YourService
    arguments:
        - "@your_bundle.your_entity_repository"
    calls:
        - [setContainer, ['@service_container']]

Answer 3

您的服务声明中有错字，您忘记了 "repository" 命名空间。另外，class 位于 "Entity" 还是 "Repository"？服务 ID 应与实际的完全限定 class 名称相同。在 services.yml 中，尝试：

CbmLtd\UvmsBundle\Repository\DealerRepository:
    class: CbmLtd\UvmsBundle\Repository\DealerRepository

而不是：

CbmLtd\UvmsBundle\DealerRepository:
    class: CbmLtd\UvmsBundle\Entity\DealerRepository

Answer 4

2018+ 和 Symfony 3.3+ 答案

您可以更进一步，使用 Repositories as Services。

这样你就可以在服务配置中使用 Symfony 的自动装配和简单配置。

1。服务

services:
    _defaults:
        autowire: true
        autoconfigure: true

    CbmLtd\UvmsBundle\:
        resource: '../../vendor/cbmltd/uvms-bundle/*'
        exclude: '../../vendor/cbmltd/uvms-bundle/{Entity}'

    UvmsApiV1Bundle\:
        resource: '../../src/UvmsApiV1Bundle/*'
        exclude: '../../src/UvmsApiV1Bundle/{Entity}'

2。存储库

namespace CbmLtd\UvmsBundle\Repository\DealerRepository;

final class DealerRepository
{
    /**
     * @var Doctrine\ORM\EntityRepository
     */
    private $repository;

    public function __construct(EntityManagerInterface $entityManager)
    {
        $this->repository = $entityManager->getRepository(Dealer::class);
    }

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