【问题描述】：

按照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;
    

我似乎犯了某种错误，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：找不到类 'AppBundle\DependencyInjection\Configuration' "type":1,"file":"/var/www/dev.investmentopportunities. pl/src/AppBundle/DependencyInjection/AppExtension.php","line":22,"level":6143,"stack":[]

不幸的是，我在自己查找错误时遇到了问题。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 所建议的那样，我也尝试删除“使用”命令。这导致：

PHP 致命错误：在第 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：找不到类 '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] 试图从命名空间“AppBundle\Dependenc”加载类“配置” y 注射”。 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 pendencyInjection\Configuration", "Genemu\Bundle\FormBundle\DependencyInje 操作\配置”、“教义\ORM\配置”、“教义\DBAL\Configur ation", "Doctrine\Bundle\DoctrineCacheBundle\DependencyInjection\Configurat ion", "Symfony\Bundle\SwiftmailerBundle\DependencyInjection\Configuration", "Symfony\Bundle\MonologBu​​ndle\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\DependencyInjection\Configur ation”或“Doctrine\Bundle\DoctrineBundle\DependencyInjection\Configuration “？

从浏览器访问网页看起来有点奇怪并不会导致任何错误。

【问题讨论】：

在这种情况下不需要使用命名空间，因为两个文件都驻留在同一个目录中，并且被同一个命名空间所包围，您可以直接使用它而无需use声明。

您好，感谢您提供线索。我一开始就试过了，但还是报错了。

如果您在开发环境中运行项目，请尝试在开发环境中清除缓存。大多数时候清除缓存都对我有用。

【参考方案1】：

刚刚添加到Configuration.php的第一行：

<?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...也许您忘记再添加一个 end()...
