Laravel 5.2服务提供商无法启动

Question

我与服务提供商有一个奇怪的问题。我在dd("I'm loaded");函数中有一个boot()的ComposerServiceProvider。什么也没发生。

我在config / app.php中也有App\Providers\ComposerServiceProvider::class。我跑了几次composer dump-autoload。有人可以帮忙吗？

<?php namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class ComposerServiceProvider extends ServiceProvider {

    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        dd("I'm loaded");
    }

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

}

编辑：这是我的bootstrap / cache / services.php，即使在php artisan clear-compiled之后它也没有出现

Answer 1

在rodrigo.pedra的另一个论坛上找到答案：

php artisan config:clear
php artisan clear-compiled

第一个将清除所有缓存的配置文件，后者将清除服务缓存

Answer 2

你说你试过php artisan clear-compiled和composer dump-autoload，但是你试过运行所有这些命令吗？

php artisan clear-compiled 
composer dump-autoload
php artisan optimize

Answer 3

我也有一个奇怪的问题：延迟提供者，直到我看到这个

  

要延迟加载提供程序，请将defer属性设置为true并定义提供方法。 provide方法返回提供者注册的服务容器绑定：

Laravel Documentation

Answer 4

如果您的ServiceProvider类实现boot()方法，请确保您也调用parent::boot()方法。

至少在我的情况下（Laravel 5.3.6），丢失的parent::boot()阻止了服务提供商正常启动。

Answer 5

php artisan clear-compiled 
composer dump-autoload

上面的命令有效，但就我而言，我必须删除 storage/views/ 下的所有文件才能使用我的供应商提供的指令刀片。
