Php 为什么symfony容器有重复的服务?
我想将classPhp 为什么symfony容器有重复的服务?,php,symfony,symfony4,Php,Symfony,Symfony4,我想将classApp\Service\SomeService注册为服务 这是我的服务。yaml: services: _defaults: autowire: false autoconfigure: true public: true App\: resource: '../src/*' exclude: '../src/{Entity,Migrations,Tests,Kernel.php}'
App\Service\SomeService
注册为服务
这是我的服务。yaml
:
services:
_defaults:
autowire: false
autoconfigure: true
public: true
App\:
resource: '../src/*'
exclude: '../src/{Entity,Migrations,Tests,Kernel.php}'
App\Controller\:
resource: '../src/Controller'
tags: ['controller.service_arguments']
someservice:
class: App\Service\SomeService
现在我运行debug:container someservice
:
Information for Service "someservice"
=====================================
---------------- -------------------------
Option Value
---------------- -------------------------
Service ID someservice
Class App\Service\SomeService
Tags -
Public yes
Synthetic no
Lazy no
Shared yes
Abstract no
Autowired no
Autoconfigured yes
---------------- -------------------------

Service ID App\Service\SomeService

而且,当我运行debug:container-App\\Service\\SomeService
时:
Information for Service "someservice"
=====================================
---------------- -------------------------
Option Value
---------------- -------------------------
Service ID someservice
Class App\Service\SomeService
Tags -

因此,我有另一个指向同一类的服务:
namespace App\Controller;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use App\Service\SomeService;
class DefaultController extends Controller
{
/**
* @Route("/")
* @return Response
*/
public function index()
{
var_dump($this->get('someservice') === $this->get(SomeService::class));
return new Response;
}
}
产出:
布尔(假)
为什么我要注册两个服务而不是一个服务?这是因为您在
服务中注册了两次。yaml
使用此行自动执行一次:
App\:
resource: '../src/*'
exclude: '../src/{Entity,Migrations,Tests,Kernel.php}'
另一种是手动:
someservice:
class: App\Service\SomeService
因为它们的名称不同(someservice
和App\Service\someservice
),所以Symfony的名称不同
我建议您删除第二个声明,并仅在控制器中使用其完全限定名调用服务:$this->get(SomeService::class)
