移動Symfony2的服務配置捆綁

Question

我在config.yml

services: 
    my.user_provider: 
     class: Acme\MySecurityBundle\Security\UserProvider 

以下，但想動這在我MySecurityBundle/Resources/config到config.yml但Symfony2的告訴我，該服務不存在時我動它。

如何從中獲取config.yml文件？

Answer 1

src/Acme/MySecurityBundle/DependencyInjection/MySecurityExtension.php：

<?php 
namespace Acme\MySecurityBundle\DependencyInjection; 

use Symfony\Component\HttpKernel\DependencyInjection\Extension; 
use Symfony\Component\DependencyInjection\ContainerBuilder; 
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader; 
use Symfony\Component\Config\FileLocator; 

class MySecurityExtension extends Extension 
{ 
    public function load(array $configs, ContainerBuilder $container) 
    { 
     $loader = new YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config')); 
     $loader->load('services.yml'); 
    } 
} 

src/Acme/MySecurityBundle/Resources/config/services.yml：

services: 
    my_security.user_provider: 
     class: Acme\MySecurityBundle\Security\UserProvider

我完成了這一由app/config.yml引用它作爲一個進口：

imports: 
    - { resource: "@MySecurityBundle/Resources/config/services.yml" }

你需要在包稱爲「擴展」，告訴Symfony的做什麼加載軟件包時，創建一個類。命名約定有點奇怪。對於Acme \ MySecurityBundle，該類將被命名爲AcmeMySecurityExtension。它位於{bundlepath}/DependencyInjection中。

這裏是我的一個示例（我加載資源/配置/ services.xml中）：

<?php 

namespace Acme\MySecurityBundle\DependencyInjection; 

use Symfony\Component\Config\FileLocator; 
use Symfony\Component\DependencyInjection\ContainerBuilder; 
use Symfony\Component\DependencyInjection\Loader\XmlFileLoader; 
use Symfony\Component\HttpKernel\DependencyInjection\Extension; 

/** 
* This class is automatically discovered by the kernel and load() is called at startup. 
* It gives us a chance to read config/services.xml and make things defined there available for use. 
* For more information, see http://symfony.com/doc/2.0/cookbook/bundles/extension.html 
*/ 
class AcmeMySecurityExtension extends Extension 
{ 
    /** 
    * Called by the kernel at load-time. 
    */ 
    public function load(array $configs, ContainerBuilder $container) 
    { 
     /*@var XmlFileLoader*/ 
     $loader = new XmlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config')); 
     $loader->load('services.xml'); 
    } 
}
