如何覆蓋bundle的DependencyInjection部分？

Question

我想越過部分FOSElasticaExtension https://github.com/FriendsOfSymfony/FOSElasticaBundle來處理配置和參數，通過bundle繼承有點不同（這裏稍微描述一下http://symfony.com/doc/master/cookbook/bundles/override.html）。不幸的是，這方面的文檔是缺乏的，並且在嘗試覆蓋時出現奇怪的錯誤（比如完全沒有注入配置）。

vendor/acme/Acme/ElasticaBundle/AcmeElasticaBundle.php

<?php 
namespace Acme\ElasticaBundle; 

use Symfony\Component\HttpKernel\Bundle\Bundle; 

/** 
* Extends FOS Elastica bundle. 
*/ 
class AcmeElasticaBundle extends Bundle 
{ 
    public function getParent() 
    { 
     return 'FOSElasticaBundle'; 
    } 
} 

vendor/acme/Acme/ElasticaBundle/DependencyInjection/Configuration.php

<?php 
namespace Acme\ElasticaBundle\DependencyInjection; 

use Symfony\Component\Config\Definition\Builder\ArrayNodeDefinition; 
use Symfony\Component\Config\Definition\Builder\TreeBuilder; 
use Symfony\Component\Config\Definition\ConfigurationInterface; 

use FOS\ElasticaBundle\DependencyInjection\Configuration as BaseConfiguration; 

class Configuration extends BaseConfiguration 
{ 
} 

vendor/acme/Acme/ElasticaBundle/DependencyInjection/AcmeElasticaExtension.php

<?php 
namespace Acme\ElasticaBundle\DependencyInjection; 

use Symfony\Component\DependencyInjection\Loader\XmlFileLoader; 
use Symfony\Component\DependencyInjection\ContainerBuilder; 
use Symfony\Component\DependencyInjection\Definition; 
use Symfony\Component\DependencyInjection\DefinitionDecorator; 
use Symfony\Component\DependencyInjection\Reference; 
use Symfony\Component\Config\FileLocator; 

use FOS\ElasticaBundle\DependencyInjection\FOSElasticaExtension as Extension; 

/** 
* Overrides some parts of FOS Elastica extension. 
*/ 
class AcmeElasticaExtension extends Extension 
{ 
} 

app/AppKernel.php

<?php 
use Symfony\Component\HttpKernel\Kernel; 
use Symfony\Component\Config\Loader\LoaderInterface; 

class AppKernel extends Kernel 
{ 
    public function registerBundles() 
    { 
     $bundles = array(
      new FOS\ElasticaBundle\FOSElasticaBundle(), 
      new Acme\ElasticaBundle\PhoenixElasticaBundle(), 
     ); 
    } 
} 

錯誤：

ErrorException: Notice: Undefined index: indexes in /home/tatsh/test-site/vendor/friendsofsymfony/elastica-bundle/FOS/ElasticaBundle/DependencyInjection/Configuration.php line 367 

也就是說這一行：https://github.com/FriendsOfSymfony/FOSElasticaBundle/blob/master/DependencyInjection/Configuration.php#L367

我沒有改變我的配置，所以我不知道什麼可能是原因。我認爲他們的代碼驗證配置運行良好和檢索值，但MergeExtensionConfigurationPass似乎與這個正確去：

簡單的方法來解決：實現load()方法即使存根。不要致電父母load()方法。

<?php 
/** 
* Overrides some parts of FOS Elastica extension. 
*/ 
class AcmeElasticaExtension extends Extension 
{ 
    public function load(array $configs, ContainerBuilder $container) 
    { 
    } 
}
