我创建了一个新的 symfony 5.3 项目。我正在使用六边形架构开发这个应用程序。

我添加了一个我为另一个 symfony 项目开发的 Bundle。此捆绑包在原始项目中工作。但在新项目中，我收到以下错误：

!!  Fatal error: Cannot declare class UserBundle\Infrastructure\DependencyInjection\MycompanyUserExtension, because the name is already in use in /var/www/html/src/Mycompany/UserBundle/Infrastructure/DependencyInjection/MycompanyUserExtension.php on line 11
!!  Symfony\Component\ErrorHandler\Error\FatalError {#419
!!    -error: array:4 [
!!      "type" => 64
!!      "message" => "Cannot declare class UserBundle\Infrastructure\DependencyInjection\MycompanyUserExtension, because the name is already in use"
!!      "file" => "/var/www/html/src/Mycompany/UserBundle/Infrastructure/DependencyInjection/MycompanyUserExtension.php"
!!      "line" => 11
!!    ]
!!    #message: "Compile Error: Cannot declare class UserBundle\Infrastructure\DependencyInjection\MycompanyUserExtension, because the name is already in use"
!!    #code: 0
!!    #file: "./src/Mycompany/UserBundle/Infrastructure/DependencyInjection/MycompanyUserExtension.php"
!!    #line: 11
!!  }

文件夹结构是：

src
  |- Mycompany
     |- UserBundle
        |- MycompanyUserBundle.php
        |- Domain
        |- Infrastructure
           |- DependencyInjection
           |  |- MycompanyUserExtension.php
           |- Resources
              |- config
                 |- routes.yaml
                 |- services.yaml

MycompanyUserBundle 的代码是：

# src/Mycompany/UserBundle/MycompanyUserBundle.php
namespace UserBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;
use UserBundle\Infrastructure\DependencyInjection\MycompanyUserExtension;

class MycompanyUserBundle extends Bundle
{
    public function getContainerExtension()
    {
        if (null === $this->extension) {
            $this->extension = new MycompanyUserExtension();
        }
        return $this->extension;
    }
}

MycompanyUserExtension 的代码是：

# src/Mycompany/UserBundle/Infrastructure/DependencyInjection/MycompanyUserExtension.php
namespace UserBundle\Infrastructure\DependencyInjection;

use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Extension\Extension;
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;

class MycompanyUserExtension extends Extension
{

    public function load(array $configs, ContainerBuilder $container)
    {
        $loader = new YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
        $loader->load('services.yaml');
    }

    public function getAlias()
    {
        return 'user_bundle';
    }

}

命名空间 UserBundle 在 composer.json 中声明

"autoload": {
        "psr-4": {
            "UserBundle\\": "src/Mycompany/UserBundle",
            "App\\": "src/"
        }
    },

并且捆绑也在 config/bundles.php 中声明为UserBundle\MycompanyUserBundle::class => ['all' => true],

该捆绑包也在映射下的 config/packages/doctrine.yaml 中引用

UserBundle:
  is_bundle: false
  type: annotation
  dir: '%kernel.project_dir%/src/Mycompany/UserBundle/Domain/Entity'
  prefix: 'UserBundle\Domain\Entity'
  alias: UserBundle

MycompanyUserExtension仅在错误说它正在使用的同一文件中声明，我没有找到此类的任何重复声明。但是项目没有编译，因为有错误。这是一个全新的项目，还没有任何代码或捆绑包。

最后我发现了问题。在 config/services.yaml 中，我在 App 之前声明了 UserBundle\，我的包位于 src 文件夹中。所以它读取了 UserBundle 两次。

我宣布：

UserBundle\:
    resource: '../src/Mycompany/UserBundle/'
    exclude:
        - '../src/Mycompany/UserBundle/Domain/Entity/'
        - '../src/Mycompany/UserBundle/Infrastructure/DependencyInjection/'

App\:
    resource: '../src/'
    exclude:
        - '../src/DependencyInjection/'
        - '../src/Entity/'
        - '../src/Kernel.php'
        - '../src/Tests/'

所以我只需要Mycompany在 App/ 声明中排除文件夹

- '../src/Mycompany/'
