php - symfony: Autowiring 接口(interface)

Question

我需要做什么才能完成这项工作？

interface BaseServiceInterface {
   public function getRecords();
} 

class BaseService implements BaseServiceInterface{
    public function getRecords(){
        return "bla";
    }
}


class SomeOtherService{

    private $baseService;

    public function __construct(BaseServiceInterface $baseService){
         $this->baseService = $baseService;
    }
}

我的 service.yml 看起来像这样:

base_service:
    class: AppBundle\Service\BaseService
    autowire: true

当我尝试运行它时，我得到:

Cannot autowire argument 1 for AppBundle\Service\SomeOtherService because the type-hinted class does not exist (Class BaseServiceInterface does not exist).

Answer 1

Autowiring 不直接与接口(interface)一起工作。 您需要创建服务别名才能使其正常工作。

services:
    AppBundle\Service\BaseServiceInterface: '@AppBundle\Service\BaseService'
