Symfony2 yml：將相同的參數傳遞給每個服務

我試圖重用[@ service_container，@ doctrine.orm.entity_manager]作爲單個變量，但似乎無法弄清楚。我計劃在添加更多模型時重用。Symfony2 yml：將相同的參數傳遞給每個服務

services: 
    generalfunctions: 
     class: classes\classBundle\Controller\DefaultController 
    functionsClass: 
     class: classes\classBundle\Classes\functionsClass  
     arguments: [@service_container,@doctrine.orm.entity_manager] 
    OtakuClass: 
     class: classes\classBundle\Models\otakusModel 
     arguments: [@service_container,@doctrine.orm.entity_manager]

你可能想看看到[自動連線]（http://symfony.com/blog/new-in-symfony-2-8-service-auto-wiring）功能服務也可能是一種可行的方法：http://symfony.com/doc/current/components/dependency_injection/parentservices.html。傳遞容器以及實體管理器似乎很奇怪。 – Federkun

您可以：

理會
通唯一的服務容器，並從它那裏得到的所有服務
創建自己的類僅包含重複的服務和方法getServiceContainer（）， getEntityManager（）等
使用autowire - http://symfony.com/doc/current/components/dependency_injection/autowiring.html

Opps，應該知道我可以從服務容器中獲取實體管理器 –

謝謝大家，我最終創建了一個基類，所有的模型都擴展了這個基類。我不知道你可以從服務對象中複製實體管理器。
