dependency-injection - 通过 services.yml 将自定义实体存储库类传递给服务

Question

我尝试通过 services.yml 使用自定义存储库加载我的服务

我现在有:

parameters:
    job_entity_name:  Marek\JobeetBundle\Entity\Job
    category_entity_name:  Marek\JobeetBundle\Entity\Category

services:
  job_metadata:
    class: Doctrine\ORM\Mapping\ClassMetaData
    arguments: 
      name: [%job_entity_name%]
  category_metadata:
    class: Doctrine\ORM\Mapping\ClassMetaData
    arguments: 
      name: [%category_entity_name%]
  job_repo:
    class: Marek\JobeetBundle\Repositories\JobRepository
    arguments: 
      em: [@doctrine.orm.entity_manager]
      class: [@job_metadata] 
  category_repo:
    class: Marek\JobeetBundle\Repositories\CategoryRepository
    arguments: 
      em: [@doctrine.orm.entity_manager]
      class: [@category_metadata]      
  job_service:
    class: Marek\JobeetBundle\JobService
    arguments:    
      jobRepo: [@job_repo]
      categoryRepo: [@category_repo]

错误:

Notice: Array to string conversion in D:\Devel\symfony2\jobeet\vendor\doctrine\lib\Doctrine\ORM\Mapping\ClassMetadata.php line 66

我放弃。有人可以帮忙吗？

当然我的架构不好，正确的是:

services:
  job_metadata:
    class: Doctrine\ORM\Mapping\ClassMetaData
    arguments: 
      name: "Marek\JobeetBundle\Entity\Job"
  category_metadata:
    class: Doctrine\ORM\Mapping\ClassMetaData
    arguments: 
      name: "Marek\JobeetBundle\Entity\Category"
  job_repo:
    class: Marek\JobeetBundle\Repositories\JobRepository
    arguments: 
      em: @doctrine.orm.entity_manager
      class: @job_metadata 
  category_repo:
    class: Marek\JobeetBundle\Repositories\CategoryRepository
    arguments: 
      em: @doctrine.orm.entity_manager
      class: @category_metadata      
  job_service:
    class: Marek\JobeetBundle\JobService
    arguments:    
      jobRepo: @job_repo
      categoryRepo: @category_repo

在这个答案中，您将找到一种将存储库定义为服务的更好方法(即使用 factory-services 和 factory-methods)。
