Laravel 5.2 服务提供商未启动

Question

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

我在config/app.php中也有App\Providers\ComposerServiceProvider::class。我运行composer dump-autoload好几次了。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，它也没有出现，即使在 php artisan clear-compiled

之后

Answer 1

您说您尝试了 php artisan clear-compiled 和 composer dump-autoload 但您是否尝试过运行所有这些命令？

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

Answer 2

在另一个论坛上从 rodrigo.pedra 得到了答案：

php artisan config:clear
php artisan clear-compiled

第一个将清除所有缓存的配置文件，第二个将清除服务缓存

Answer 3

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

至少在我的情况下 (Laravel 5.3.6) 丢失的 parent::boot() 导致服务提供商无法正常启动。

Answer 4

我也有一个奇怪的问题：延迟提供者，直到我看到这个

To defer the loading of a provider, set the defer property to true and define a provides method. The provides method returns the service container bindings that the provider registers:

Laravel Documentation

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提供商的指令 blade。
