php - laravel 5.1 中的 Queue::after() 不起作用

Question

我想在队列处理后运行一些语句，但 Queue::after 块没有被执行，谁能帮我如何运行 Queue::after 块

<?php

namespace test\Providers;
use Log;
use Queue;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        Log::info('log1');
       Queue::after(function ($connection, $job, $data) {
       Log::info('log2');
        });
    }

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

    }
}

示例输出：在 laravel.log 中：仅“log1”打印
