Symfony2 中的自定义配置

Question

我开发了一个小包，提供 标签云 功能。将它包含在其他 Symfony 项目中应该很容易，因此它需要是可配置的。我发现了 3 页：

我按照示例进行了操作，但很明显，我错过了一些东西，因为我在使用 php app/console config:dump-reference:

时收到以下错误消息

[Symfony\Component\Config\Exception\FileLoaderLoadException] There is no extension able to load the configuration for "loew_tag" (in somePath/blog/app/config/../../src/Loew/TagBundle/Resources/config/config.yml). Looked for namespace "loew_tag", found " ... " in somePath/blog/app/config/../../src/Loew/TagBundle/Resources/config/config.yml (which is being imported from "somePath/blog/app/config/config.yml").

和

[Symfony\Component\DependencyInjection\Exception\InvalidArgumentException]
There is no extension able to load the configuration for "loew_tag" (in /home/somePath/blog/app/config/../../src/Loew/TagBundle/Resources/config/config.yml). Looked for namespace "loew_tag", found "framework", "security", "twig", "monolog", "swiftmailer", "assetic", "doctrine", "sensio_framework_extra", "blog", "fos_user", "debug", "web_profiler", "sensio_distribution"

我在 'blog bundle' 中工作并尝试访问 'tag bundle' 的配置数据。

我的顶 'app/config/config.yml':

imports:
- { resource: parameters.yml }
- { resource: security.yml }
- { resource: services.yml }
- { resource: ../../src/Loew/TagBundle/Resources/config/services.yml }
- { resource: ../../src/Loew/TagBundle/Resources/config/config.yml }

LoewTagExtension.php:

<?php
// Loew/TagBundle/DependencyInjection/LoewTagExtension.php

namespace Loew\TagBundle\DependencyInjection;

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

class LoewTagExtension extends Extension
{
    /**
     * {@inheritdoc}
     */
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

        //$container->setParameter('food_entities',     $config['food_entities']);
        $container->setParameter('split_match', $config['split_match']);

        $loader = new Loader\YamlFileLoader($container, new   FileLocator(__DIR__.'/../Resources/config'));
        $loader->load('config.yml');
        $loader->load('services.yml');
        }
    }

config.yml:

loew_tag:
#    food_entities:
#     - "BlogBundle:Article"
#     - "BlogBundle:Comment"
    split_match: "/[^0-9a-zA-ZöÖüÜäÄß]/"

Configuration.php:

<?php
// Loew/TagBundle/DependencyInjection/Configuration.php


namespace Loew\TagBundle\DependencyInjection;

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

class Configuration implements ConfigurationInterface
{
    /**
     * {@inheritdoc}
     */
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder();

        $rootNode = $treeBuilder->root('loew_tag');

        $rootNode
            ->children()
            ->scalarNode('split_match')->end()
//                ->arrayNode('food_entities')
//                ->prototype('scalar')->end()

            ->end();

        return $treeBuilder;
    }
}

节点 food_entities 的条目在所有文件中都有注释，以使其尽可能简单。

我注意到，有人问过类似的问题，相关问题已经解决，但我无法将解决方案转移到这个问题上。

知道吗，我想念什么？

终于解决了

牢记命名约定，尤其是 Jakub Zalas 指出的部分
正在从扩展文件中删除条目：$loader->load('config.yml');。

显然，配置文件将在服务加载后立即自动加载。
