Laravel 路由到子文件夹中的控制器出错

Question

我发现很多关于将控制器放在子文件夹中的帖子，大多数（如果不是全部）似乎都与命名空间或命名问题有关。我似乎无法让它工作，并不断收到以下 ReflectionException 和 FatalError 报告 class 正在使用中。

我试过使用不同的 class 名称，但没有解决任何问题。只要我路由到 Admin folder/namespace 中的控制器，我就会收到列出的错误。每次更改后我都有运行 composer dump-autoload 和运行 php artisan cache:clear 只是为了安全

我的文件夹结构

/app/
    Console/
    Exceptions/
    Http/
        Controllers/
            Admin/
                DashboardController.php
            Auth/
            Controller.php
            ...OtherController.php files live here in the base Controller folder
        Middleware/
    Providers/

/routes/web.php

...
// Admin Routes
Route::group( [ 'namespace' => 'Admin','prefix' => 'admin' ], function(){

    Route::get( '/', 'DashboardController@showAdminHome' )->name( 'admin.dashboard' ); 

});

/app/Http/Controllers/Admin/DashboardController.php

<?php

namespace App\Http\Controller\Admin;

use App\Http\Controllers\Controller;

class DashboardController extends Controller {

    public function showAdminHome() {
        return view( 'admin.dashboard' );
    }

} //- END Admin\DashboardController{}

我运行没有办法尝试并感谢任何帮助。

Answer 1

您需要使用正确的命名空间来修复错误：

namespace App\Http\Controllers\Admin;

Answer 2

检查您的命名空间并在命名空间中添加完整路径。

命名空间App\Http\Controllers\Admin;
