php - Laravel 5 找不到自定义命名空间的类

Question

在我的 Laravel 应用程序中，我将前端和后端代码拆分到文件夹中。这些是 app/Http/Controllers/BackEnd和 app/Http/Controllers/FrontEnd .我认为定义两个命名空间 BackEnd 会更容易，而不是在每个文件上键入所有内容。和 FrontEnd .我已经将我的 Composer 文件编辑为:

"autoload": {
    "classmap": [
        "app/Models",
        "database"
    ],
    "psr-4": {
        "App\\": "app/",
        "BackEnd\\": "app/Http/Controllers/BackEnd",
        "FrontEnd\\": "app/Http/Controllers/FrontEnd"
    }
},

然后我运行 composer autodump 并像这样设置我的路由文件:

Route::group(['prefix' => 'webman', 'middleware' => 'auth', 'namespace' => 'BackEnd'], function()
{
   Route::get('/', ['as' => 'webmanHome', 'uses' => 'HomeController@index']); 
});

但是当我浏览到 localhost:8000/webman/我刚收到一个错误，Class App\Http\Controllers\BackEnd\HomeController does not exist . Controller 确实存在，这是文件:

<?php namespace BackEnd;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

class HomeController extends Controller {

    /**
     * Display the admin home page, showing the front-end menu and "apps" as links to other sections of the ACP.
     *
     * @param Reqeust       $request
     *
     * @return View
     */
    public function index(Request $request)
    {
        return view('backend.index');
    }

}

我检查过 vendor/composer/autoload_psr4.php确保命名空间被定义，它在返回的数组中 'BackEnd\\' => array($baseDir . '/app/Http/Controllers/BackEnd'), .

奇怪的是，如果我使用 <?php namespace App\Http\Controllers\BackEnd;在 HomeController.php 的顶部然后一切正常，为什么？我错过了什么？为什么不能自动加载找到文件 BackEnd ？

在 Route::group() 中设置 namespace 时，它实际上是将其附加到 App\Http\Controllers。你可以做的是删除它并像这样引用完整路径:

Route::group(['prefix' => 'webman', 'middleware' => 'auth'], function()
{
    Route::get('/', ['as' => 'webmanHome', 'uses' => '\BackEnd\HomeController@index']); 
});
