【问题描述】：

我正在尝试在 Symfony 中设置新项目。当我添加自己的 Bundle 时，出现了这个奇怪的东西：

php 致命错误：未捕获 Symfony\Component\Debug\Exception\ClassNotFoundException：试图从命名空间“ContactBoxBundle”加载类“ContactBoxBundle”。 您是否忘记了另一个名称空间的“使用”语句？在 /home/doro/projects/ContactBox/app/AppKernel.php:18 堆栈跟踪：

0 /home/doro/projects/ContactBox/vendor/symfony/symfony/src/Symfony/Component/HttpKernel/Kernel.php(450)：AppKernel->registerBundles()

1 /home/doro/projects/ContactBox/vendor/symfony/symfony/src/Symfony/Component/HttpKernel/Kernel.php(116)：Symfony\Component\HttpKernel\Kernel->initializeBundles()

2 /home/doro/projects/ContactBox/vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Console/Application.php(137): Symfony\Component\HttpKernel\Kernel->boot() H1>

3 /home/doro/projects/ContactBox/vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/Console/Application.php(124): Symfony\Bundle\FrameworkBundle\Console\Application->registerCommands()

4 /home/doro/projects/ContactBox/vendor/symfony/symfony/src/Symfony/Component/Console/Applicati in /home/doro/projects/ContactBox/app/AppKernel.php 第 18 行

我的 AppKernel 是这样的：

    <?php

use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;

class AppKernel extends Kernel

    public function registerBundles()
    
        $bundles = [
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),
            new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
            new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new ContactBoxBundle\ContactBoxBundle(),
        ];

        if (in_array($this->getEnvironment(), ['dev', 'test'], true)) 
            $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
            $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();

            if ('dev' === $this->getEnvironment()) 
                $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
                $bundles[] = new Symfony\Bundle\WebServerBundle\WebServerBundle();
            
        

        return $bundles;
    

    public function getRootDir()
    
        return __DIR__;
    

    public function getCacheDir()
    
        return dirname(__DIR__).'/var/cache/'.$this->getEnvironment();
    

    public function getLogDir()
    
        return dirname(__DIR__).'/var/logs';
    

    public function registerContainerConfiguration(LoaderInterface $loader)
    
        $loader->load($this->getRootDir().'/config/config_'.$this->getEnvironment().'.yml');
    

我真的不知道发生了什么，这是我第一次遇到这种情况，我之前在 Symfony 中做过新项目。有什么想法吗？

【问题讨论】：

在ContactBoxBundle/ContactBoxBundle.php中有没有扩展Bundle的类？

是的，我使用控制台命令生成了这个 Bundle，所以从技术上讲它应该可以工作

可能是自动加载作曲家的问题，尽管这似乎不太可能。将 composer.json 的自动加载部分粘贴到您的问题中。

AppKernel.php weird behavior的可能重复

【参考方案1】：

你的包在文件中的命名空间是什么：ContactBoxBundle/ContactBoxBundle.php？ 参考here，包名AcmeTestBundle在命名空间namespace Acme\TestBundle中；那么appKernel就是new Acme\TestBundle\AcmeTestBundle(),。 也许这就是你的问题。

【讨论】：

我不这么认为...我的命名空间是路径 src/ContactBoxBundle 的 ContactBoxBundle
