1. Tentukan kelas QrCode.php di bawah appLibraires

<?php
/**
 * Created by PhpStorm.
 * User: AIMPER
 * Date: 2016/11/30
 * Time: 10:13
 */

namespace App\Libaries;
use Endroid\QrCode;
use Illuminate\Support\Facades\DB;

class QrCode{

    public static function generateQrCode($type = null, $id = null){
        $code = random_string(32,true);
        $create_date = time();
        $expires = 0;

        $qrcodeType = DB::table('qrcode_type')->where('id','=',$type)->select('code','params')-first();
        return $qrcodeType;

    }

}

2 Panggil kaedah kelas ini

...
use App\Libaries\QrCode;
class TestController extends Controller{
    public function index(){
        QrCode::generateQrCode(11,1);
    }
}

3. Mesej ralat

ReflectionException in Route.php line 286:
Class App\Libaries\QrCode does not exist

4. Percubaan penyelesaian
Saya telah menggunakan composer dump-autoload, tetapi kelas masih tidak boleh dimuatkan secara automatik ke dalam projek?
