我正在使用laravel 5应用程序，我正在尝试调试在后台运行的数据库查询。

所以我尝试了社区中许多人尝试的方式：

https://laravel.com/docs/5.1/database#listening-for-query-events

但令我惊讶的是，我回到了laravel抛出的一个奇怪的例外：

这是痕迹，但我无法弄清楚我在这里做错了什么。

AppServiceProvider.php 

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

use DB;
use Log;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        DB::listen(function($sql, $bindings, $time) {
            Log::info($time . "\r\n" . $sql);
        });
    }

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

你在5.1吗？这表明你可能在5.2：
