无法将控制器类移动到其他文件夹

Question

我从另一个开发人员那里接手了一个项目，所以我想把他的很多代码移到一个临时文件夹中，把事情弄清楚，如果我需要任何例子，我会回到他的东西上去。

因此，在将他的一个控制器类移动到临时文件夹“src/controller/temp”时，我得到以下消息：

自动加载程序需要在文件“/var/www/vhosts/mywebsite.com/vendor/composer/./../src/Controller/Temp/AccountSetupController.php”中定义类“App\Controller\Temp\AccountSetupController”。找到了文件，但类不在其中，类名称或命名空间可能在/var/www/vhosts/mywebsite中有输入错误。com/config/services。yaml（加载在resource“/var/www/vhosts/mywebsite.com/config/services.yaml”中）。

以下是控制器类（AcCountSetupController.php）的开头（我从 /src/Controller/CreatorDashboard移动到 /src/Controller/Temp）：

namespace App\Controller\CreatorDashboard;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;

/**
* @Route("/dashboard/setup")
*/
class AccountSetupController extends Controller
{

我的services.yaml文件是这样的：

# This file is the entry point to configure your own services.
# Files in the packages/ subdirectory configure your dependencies.

# Put parameters here that don't need to change on each machine where the app is deployed
# https://symfony.com/doc/current/best_practices/configuration.html#application-related-configuration
parameters:
    locale: 'en'
    aws.bucket: 'bucket'
    aws.compliance.bucket: 'bucket.compliance'
    num_notification_records: 5
    default_profile_photo_id: 1

services:
    # default configuration for services in *this* file
    _defaults:
        autowire: true      # Automatically injects dependencies in your services.
        autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.
        public: false       # Allows optimizing the container by removing unused services; this also means
                            # fetching services directly from the container via $container->get() won't work.
                            # The best practice is to be explicit about your dependencies anyway.

    Liip\ImagineBundle\Service\FilterService: '@liip_imagine.service.filter'

    Imagine\Image\ImagineInterface: '@liip_imagine.gd'

    App\Repository\PhotoRepository:
        arguments: ['@liip_imagine.imagine_interface']


    # makes classes in src/ available to be used as services
    # this creates a service per class whose id is the fully-qualified class name
    App\:
        resource: '../src/*'
        exclude: '../src/{DependencyInjection,Entity,Migrations,Tests,Kernel.php}'

    # controllers are imported separately to make sure services can be injected
    # as action arguments even if you don't extend any base controller class
    App\Controller\:
        resource: '../src/Controller'
        tags: ['controller.service_arguments']

    # add more service definitions when explicit configuration is needed
    # please note that last definitions always *replace* previous ones

它以前工作得非常好，我所做的只是将控制器类移动到另一个位置。

为什么自动加载程序不能加载已移动的控制器类？

Answer 1

Symfony文件和名称空间使用composer提供的PSR4自动加载标准。json

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

因此，文件和名称空间有着密切的关系。

• 文件src/Controller/CreatorDashboard/AcCountSetupController.php将具有命名空间命名空间App\Controller\CreatorDashboard；
• 当文件src/Controller/Temp/AcCountSetupController.php应该有一个命名空间命名空间App\Controller\Temp；
