Symfony - 在服务中注入学说存储库

2022-01-03 00:00:00 php symfony doctrine-orm symfony-3.4

根据如何将存储库注入到Symfony2 中的服务?就像

acme.custom_repository:
    class: DoctrineORMEntityRepository
    factory: ['@doctrine.orm.entity_manager', getRepository]
    arguments:
        - 'AcmeFileBundleModelFile'

但我得到一个例外

无效的服务acme.custom_repository":类"EntityManager5aa02de170f88_546a8d27f194334ee012bfe64f629947b07e4919__CG__DoctrineORMEntityManager"不存在.

Invalid service "acme.custom_repository": class "EntityManager5aa02de170f88_546a8d27f194334ee012bfe64f629947b07e4919__CG__DoctrineORMEntityManager" does not exist.

我怎样才能在 Symfony 3.4 中做到这一点?

How can I do this in Symfony 3.4?

EntityClass 实际上是一个有效的 FQCN 类(当然也使用了 phpstorm 上的复制引用)，只是将其重命名，因为其中包含公司名称 :).无论如何更新它.

EntityClass is actually a valid class FQCN (also used copy reference on phpstorm to be sure) , just renamed it because a companies name is in it :). updated it anyway.

BlueM 的解决方案完美运行.如果您不使用自动装配，这里是服务定义:

BlueM's solution works perfectly. In case you are not using autowiring here's the service defintion:

AcmeAcmeBundleRespositoryMyEntityRepository:
    arguments:
        - '@DoctrineCommonPersistenceManagerRegistry'
        - AcmeAcmeBundleModelMyEntity # '%my_entity_class_parameter%'

推荐答案

当您使用 Symfony 3.4 时，您可以使用更简单的方法，使用 ServiceEntityRepository.只需实现您的存储库，让它extend class ServiceEntityRepository，您就可以简单地注入它.(至少在使用自动装配时——我没有在经典 DI 配置中使用它，但我认为它也应该可以工作.)

As you are using Symfony 3.4, you can use a much simpler approach, using ServiceEntityRepository. Simply implement your repository, let it extend class ServiceEntityRepository and you can simply inject it. (At least when using autowiring – I haven’t used this with classic DI configuration, but would assume it should also work.)

换句话说:

namespace AppRepository;

use DoctrineBundleDoctrineBundleRepositoryServiceEntityRepository;
use DoctrineCommonPersistenceManagerRegistry;

class ExampleRepository extends ServiceEntityRepository
{
    /**
     * @param ManagerRegistry $managerRegistry
     */
    public function __construct(ManagerRegistry $managerRegistry)
    {
        parent::__construct($managerRegistry, YourEntity::class);
    }
}

现在，无需任何 DI 配置，您可以在任何地方注入存储库，包括控制器方法.

Now, without any DI configuration, you can inject the repository wherever you want, including controller methods.

一个警告(同样适用于您尝试注入存储库的方式):如果 Doctrine 连接被重置，您将拥有对陈旧存储库的引用.但恕我直言，这是我接受的风险，否则我将无法直接注入存储库..

One caveat (which equally applies to the way you try to inject the repository): if the Doctrine connection is reset, you will have a reference to a stale repository. But IMHO, this is a risk I accept, as otherwise I won’t be able to inject the repository directly..
