Laravel 命令队列异常

Question

我正在尝试实现一个 Laravel 5 队列，它将新的事件邮件发送到邮件列表。我发现您可以为此使用命令，但每次尝试执行此命令时都会出现错误异常（见下文）。我写的邮件类如下

<?php namespace App\Commands;

use Illuminate\Support\Facades\App;
use \App\Event;
use Illuminate\Support\Facades\Mail;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Bus\SelfHandling;
use Illuminate\Contracts\Queue\ShouldBeQueued;

class EventMailing extends Command implements SelfHandling, ShouldBeQueued {

    use InteractsWithQueue, SerializesModels;

    /**
     * Create a new command instance.
     *
     * @return void
     */

    public $event;
    public $recipients;

    public function __construct(Event $event, $recipients)
    {
        $this->event=$event;
        $this->recipients=$recipients;
    }

    /**
     * Execute the command.
     *
     * @return void
     */
    public function handle(EventMailing $command, User $user)
    {
        $event = $command->event;

        print_r($event);

       /* foreach ($this->recipients as $recipient) {
            Mail::send('emails.event', $event,
                function($message) use ($event,$recipient)
                {
                    $message->from('info@gsebelux.org', 'GSE BeLux');
                    $message->subject('New event: '.$event->name);
                    $message->to($recipient);
                }
            );
        }*/
    }

}

注意：我将邮件部分注释掉以检查是否不是该部分出现故障。

我从控制器调用 EventMailing 命令，如下所示：

public function sendMail($event,$array)
{
    Queue::push(new EventMailing($event,$array));
} 

当我触发此功能并执行 php artisan queue:work --verbose 我明白了。谁能帮我解决这个问题？

改变

public function handle(EventMailing $command, User $user)
{
    $event = $command->event;

    print_r($event);

通过

public function handle(User $user)
{
    //event is in the constructor
    $event = $this->event;

    print_r($event);
