php - Symfony 设置扩展类的依赖注入(inject)

Question

我想像这样注入(inject)抽象类:

services:
    App\Infrastructure\Persistence\BaseDoctrineRepository:
        arguments:
          $eventStore: '@broadway.event_store'
          $registry: '@doctrine'
          $eventBus: '@broadway.event_handling.event_bus'

，但如果这样做的话我会得到:

Cannot autowire service "App\Infrastructure\Persistence\User\DoctrineUserRepository": argument "$eventStore" of method "__construct()" references interface "Broadway\EventStore\EventStore" but no such service exists. You should maybe alias this interface to one of these existing services: "broadway.event_store.dbal", "broadway.event_store.in_memory". 

所以我需要为每个存储库复制这样的代码，我想避免它。

services:
    App\Infrastructure\Persistence\User\DoctrineUserRepository:
        arguments:
          $eventStore: '@broadway.event_store'
          $registry: '@doctrine'
          $eventBus: '@broadway.event_handling.event_bus'

抽象类:

use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;

abstract class BaseDoctrineRepository extends ServiceEntityRepository
{
    public function __construct(ManagerRegistry $registry, EventStore $eventStore, EventBus $eventBus)
    {
        $this->eventStore = $eventStore;
        $this->eventBus = $eventBus;
        parent::__construct($registry, static::REPOSITORY_CLASS);
    }

从抽象中扩展的类(我想避免构造函数):

class DoctrineUserRepository extends BaseDoctrineRepository implements UserRepository
{
    const REPOSITORY_CLASS = User::class;

    public function __construct(ManagerRegistry $registry, EventStore $eventStore, EventBus $eventBus)
    {
        parent::__construct($registry, $eventStore, $eventBus);
    }

你试过这个吗https://symfony.com/doc/current/service_container/parent_services.html ？

基本上就是这样

services:
    App\Infrastructure\Persistence\BaseDoctrineRepository:
            abstract: true
            arguments:
              $eventStore: '@broadway.event_store'
              $registry: '@doctrine'
              $eventBus: '@broadway.event_handling.event_bus'
    App\Infrastructure\Persistence\User\DoctrineUserRepository:
        parent: App\Infrastructure\Persistence\BaseDoctrineRepository
