Symfony - 没有可以加载配置的扩展 - 自定义配置

直升机，

我正在尝试将自定义配置加载到我的AppBundle中 . 不幸的是我得到了：

[Symfony \ Component \ DependencyInjection \ Exception \ InvalidArgumentException]没有扩展能够加载“app”的配置（在/ var / www /dev.investmentopportunities.pl/src/AppBundle/DependencyInjection/../Resour ces /配置/ general.yml） . 寻找命名空间“app”，找不到

有几个与此错误相关的类似主题 . 我看过他们但找不到任何可以解决这个问题的解决方案 .

我的配置文件如下所示：

<?php
namespace AppBundle\DependencyInjection;

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

class Configuration implements ConfigurationInterface
{
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder();
        $rootNode = $treeBuilder->root('app');

         $rootNode
            ->children()
            ->arrayNode('tags')
            ->prototype('array')
                ->children()
                    ->scalarNode('name')->isRequired()->end()
                    ->scalarNode('role')->isRequired()->end()
                    ->scalarNode('priority')->isRequired()->end()
                    ->scalarNode('label')->isRequired()->end()
                ->end()
            ->end();

        return $treeBuilder;
    }
}

和 general.yml:

app:
    tags:
        Accepted:
            name: "Accepted"
            role: "ROLE_ACCEPTTAG"
            priority: "3"
            label: "label label-info"
        Booked:
            name: "Booked"
            role: "ROLE_ACCOUNTANT"
            priority: "3"
            label: "label label-info"
        Finalized:
            name: "Booked"
            role: "ROLE_ACCEPTDOC"
            priority: "1"
            label: "label label-success"

AppExtension.php:

<?php
namespace AppBundle\DependencyInjection;

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\Extension\PrependExtensionInterface;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader;
use Symfony\Component\Validator\Tests\Fixtures\Entity;

/**
 * This is the class that loads and manages your bundle configuration
 */
class AppExtension extends Extension
{
    /**
     * {@inheritdoc}
     */
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

        $container->setParameter('app', $config['app']);

        $loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
        $loader->load('general.yml'); # another file of yours

    }
}
