当在laravel 8中创建用户时，我如何在model中触发事件？

php artisan make:model User

use Illuminate\Database\Eloquent\Model;
use Illuminate\Contracts\Events\Dispatcher;
use Illuminate\Database\Eloquent\Concerns\HasEvents;

class User extends Model
{
    use HasEvents;

    // 模型的其余代码...
}

use Illuminate\Support\Facades\Event;
use App\Events\UserCreated;

class User extends Model
{
    use HasEvents;

    public static function boot()
    {
        parent::boot();

        static::created(function ($user) {
            event(new UserCreated($user));
        });
    }
    
    // 模型的其余代码...
}

php artisan make:event UserCreated

use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;
use App\Models\User;

class UserCreated
{
    use Dispatchable, SerializesModels;

    public $user;

    public function __construct(User $user)
    {
        $this->user = $user;
    }
}

use App\Models\User;

class UserCreatedListener
{
    public function handle(UserCreated $event)
    {
        // 处理用户创建事件的逻辑
        // 可以访问 $event->user 属性来获取用户模型实例

        // 例如，你可以在这里发送电子邮件或执行其他操作
    }
}

protected $listen = [
    UserCreated::class => [
        UserCreatedListener::class,
    ],
];
