亲爱的拉维勒/斯帕克斯，
我正在将一个旧的spark项目转换为最新版本。在我目前的版本中，我会在新用户注册到我的网站后给他们发邮件。为此，我创建了这个类：

namespace App\listeners;

use Laravel\Spark\Events\Auth\UserRegistered;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;

use Illuminate\Mail\Mailer;
use Illuminate\Support\Facades\Mail;
use Illuminate\Support\Facades\Log;
use Illuminate\Foundation\Bus\DispatchesJobs;

class HookRegisteredUser
{
use DispatchesJobs;
public function handle(UserRegistered $event)
{
$welcomeMail = new \App\Mail\Welcome($event->user);
Mail::to($event->user->email)
->send($welcomeMail);
}
}

接下来，我在app\providers\eventserviceprovider中注册这个类：

<?PHP
namespace App\Providers;

use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;

class EventServiceProvider extends ServiceProvider
{
/**
 * The event listener mappings for the application.
 *
 * @var array
 */

protected $listen = [
    // User Related Events...
    'Laravel\Spark\Events\Subscription\UserSubscribed' => [
        'App\listeners\HookRegisteredUser',
        'Laravel\Spark\Listeners\Subscription\UpdateActiveSubscription',
        'Laravel\Spark\Listeners\Subscription\UpdateTrialEndingDate',
    ],

然而，什么也没发生。有没有一种新的方法用于更新的laravel/spark版本？还是我可以试试别的？
