Class App\Http\Controllers\StudentController does not exist in Laravel 5

Question

I am building a module called Student in Laravel.

I use the routes.php file inside the Student folder to write routes realted to student module..

When I use just Route::get('/list', function () { return view('welcome');}); program working fine without error.

But when I am using Route::get('/list', 'StudentController@list'); there is a error.

Error is,

Class App\Http\Controllers\StudentController does not exist

Folder Structure

Student Controller

namespace App\Student\Controllers;

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

class StudentController extends Controller
{
    public function list(){
        echo "Hello"
    }
}

Student Service Provider

namespace App\Student;

use App\Providers\RouteServiceProvider as ServiceProvider;
use Illuminate\Support\Facades\Route;

class StudentServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        parent::boot();
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }

    /**
     * Define the routes for the application.
     *
     * @internal param Router $router
     */

    public function map()
    {
        Route::group([
            'namespace' => $this->namespace,
            'prefix' => 'students',
        ], function ($router) {
            require __DIR__ . '/routes.php';
        });
    }
}

Although laravel is magic at times, it only works if you stick the the default configuration and conventions.

You can place your controllers anywhere (heck, even load from a database and eval them) but you have to change the configuration accordingly.

I suspect you have the wrong namespace configured in RouteServiceProvider. By default it is App\Http\Controllers.

Changing default folder

If all your controllers will be in the same folder, change it to App\Student\Controllers and forget about it.

class RouteServiceProvider extends ServiceProvider
{
    // ...
    protected $namespace = 'App\Student\Controllers';
    // ...
}

Multiple modules

If you want to have multiple modules, then change your RotueServiceProvider namespace config to App and in route files use Student\Controllers\StudentController@list

class RouteServiceProvider extends ServiceProvider
{
    // ...
    protected $namespace = 'App';
    // ...
}

Route::get('/list', 'Student\Controllers\StudentController@list');
