Symfony自定义配置-命名空间问题

Question

按照在symfony2中加载应用程序的自定义配置文件时发布的建议，我陷入了名称空间问题。

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

上诉。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，将文件命名为正在执行：

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

结果：

PHP致命错误：在/var/www/dev.investmentopportunities中找不到类“AppBundle\DependencyInjection\Configuration”。pl/src/AppBundle/DependencyInjection/AppExtension。php在线22[2015-08-02 10:39:36]php。紧急情况：致命错误：未找到类“AppBundle\DependencyInjection\Configuration”{“类型”：1，“文件”：“/var/www/dev.investmentopportunities.pl/src/AppBundle/DependencyInjection/AppExtension.php”，“行”：22，“级别”：6143，“堆栈”：[]}

不幸的是，我自己找不到错误。我试图重命名文件，但仍然出现错误。你能告诉我我做错了什么吗？

更新1：

正如@San Thapa所建议的，我也尝试删除“use”命令。这导致：

PHP致命错误：在/var/www/dev.investmentopportunities中找不到类“AppBundle\DependencyInjection\Configuration”。pl/src/AppBundle/DependencyInjection/AppExtension。php第21行[2015-08-02 12:05:27]php。紧急情况：致命错误：未找到类“AppBundle\DependencyInjection\Configuration”{“类型”：1，“文件”：“/var/www/dev.investmentopportunities.pl/src/AppBundle/DependencyInjection/AppExtension.php”，“行”：21，“级别”：6143，“堆栈”：[]}

[Symfony\Component\Debug\Exception\ClassNotFoundException]试图从命名空间“AppBundle\Dependenc yInjection”加载类“Configuration”。您是否忘记了“使用”语句，例如“Symfony\Bundle\TwigBundle\DependencyInjection\Configuration”、“Symfony\Bundle\DebugBundle\DependencyInjection\Configuration”、“Symfony\Bundle\FrameworkBundle\Tests\Functional\Bundle\TestB undle\DependencyInjection\Configuration”，“Symfony\Bundle\FrameworkBundle\D ependencyInjection\Configuration”、“Genemu\Bundle\FormBundle\DependencyInjection\Configuration”、“条令\ORM\Configuration”、“条令\DBAL\Configuration”、“条令\Bundle\DoctrineCacheBundle\DependencyInjection\Configuration”、“Symfony\Bundle\SwiftmailerBundle\DependencyInjection\Configuration”Symfony\Bundle\monogbundle\DependencyInjection\Configuration”、“Symfony\Bundle\AsseticBundle\DependencyInjection\Configuration”、“Sensio\Bundle\Fr ameworkExtraBundle\DependencyInjection\Configuration”、“PUGX\AutocompleterB undle\DependencyInjection\Configuration”、“Knp\Bundle\PaginatorBundle\DependencyInjection\confFOS\UserBundle\DependencyInjection\Configuration”或“条令\Bundle\DoctrineBundle\DependencyInjection\Configuration”？

从浏览器访问网页似乎有点奇怪，但不会导致任何错误。

刚刚添加到配置的第一行。php:

<?php

并删除分号：

$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();

我不确定结构...也许你忘了再加一个结尾...
