Symfony自定义配置 - 命名空间问题

根据Loading custom config file for app in symfony2发布的建议，我陷入了命名空间问题 .

在 \src\AppBundle\DependencyInjection 我有两个文件：

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;
use AppBundle\DependencyInjection\Configuration;

/**
 * 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('kh', $config['kh']);

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

    }
}

和 Configuration.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('kh');

         $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();
        ->end();

        return $treeBuilder;
    }
}

似乎我犯了某种错误，将文件命名为执行：

php app/console cache:clear --env=prod

结果是：

PHP致命错误：第22行的/var/www/dev.investmentopportunities.pl/src/AppBundle/DependencyInjection/AppExtension.php中找不到类'AppBundle \ DependencyInjection \ Configuration'[2015-08-02 10:39:36 ] php.EMERGENCY：致命错误：未找到类'AppBundle \ DependencyInjection \ Configuration'{“type”：1，“file”：“/ var / www / dev.investmentopportunities.pl / src / AppBundle / DependencyInjection / AppExtension.php ”， “线”：22， “电平”：6143， “堆叠”：[]}

不幸的是我遇到了自己发现错误的问题 . 我试图重命名文件但仍然发生错误 . 你能告诉我我做错了什么吗？

UPDATE 1:

由于@San Thapa的消化，我也尝试删除“使用”命令 . 这导致：

PHP致命错误：第21行的/var/www/dev.investmentopportunities.pl/src/AppBundle/DependencyInjection/AppExtension.php中找不到类'AppBundle \ DependencyInjection \ Configuration'[2015-08-02 12:05:27 ] php.EMERGENCY：致命错误：未找到类'AppBundle \ DependencyInjection \ Configuration'{“type”：1，“file”：“/ var / www / dev.investmentopportunities.pl / src / AppBundle / DependencyInjection / AppExtension.php “，”“line”：21，“level”：6143，“stack”：[]} [Symfony \ Component \ Debug \ Exception \ ClassNotFoundException]尝试从命名空间“AppBundle \ Dependenc yInjection”加载类“Configuration” . 您是否忘记了“使用”声明，例如“Symfony \ Bundle \ TwigBundle \ Depend encyInjection \ Configuration”，“Symfony \ Bundle \ DebugBundle \ DependencyInjecti on \ Configuration”，“Symfony \ Bundle \ WebProfilerBundle \ DependencyInjection \ Co nfiguration”，“Symfony \ Bundle \ FrameworkBundle \ Tests \ Functional \ Bundle \ TestB undle \ DependencyInjection \ Configuration“，”Symfony \ Bundle \ FrameworkBundle \ D ependencyInjection \ Configuration“，”Genemu \ Bundle \ FormBundle \ DependencyInje ction \ Configuration“，”Doctrine \ ORM \ Configuration“，”Doctrine \ DBAL \ Configur “，”Doctrine \ Bundle \ DoctrineCacheBundle \ DependencyInjection \ Configurat ion“，”Symfony \ Bundle \ SwiftmailerBundle \ DependencyInjection \ Configuration“，”Symfony \ Bundle \ MonologBundle \ DependencyInjection \ Configuration“，”Symfony \ Bundle \ AsseticBundle \ DependencyInjection \ Configuration“ “，”Sensio \ Bundle \ Fr ameworkExtraBundle \ DependencyInjection \ Configuration“，”PUGX \ AutocompleterB undle \ DependencyInjection \ Configuration“，”Knp \ Bundle \ PaginatorBundle \ Depen dencyInjection \ Configuration“，”FOS \ UserBundle \ Dependen“ cyInjection \ Configur ation“或”Doctrine \ Bundle \ DoctrineBundle \ DependencyInjection \ Configuration“？

从浏览器访问网页似乎有点奇怪不会导致任何错误 .
