网站位置是http://somedomain.com/index.php它的文档物理路径是：

And I have these setting in
我有这些设置
C:/Apache24/htdocs/new_project/laravel/public/laravel1/app/config/app.php
providers array 'Krucas\Notification\NotificationServiceProvider'
提供者数组 'Krucas\Notification\NotificationServiceProvider'
Alias Array 'Notification'=> 'Krucas\Notification\Facades\Notification'
别名数组 'Notification'=> 'Krucas\Notification\Facades\Notification'
How can I know the Laravel maps the provider array and alias array to the physical path?
我怎么知道 Laravel 将提供者数组和别名数组映射到物理路径？

There were some cases with registration problem, cache issues, etc. Try one of these solutions:
在某些情况下会出现注册问题、缓存问题等。请尝试以下解决方案之一：
- register your provider (in main composer.json, then in config/app.php [provider & alias] ), then run
composer dump-autoload - make sure you have initiated your package : go to the folder, then
composer init - try
php artisan config:cacheor delete everything inbootstrap/cache/
- 注册您的提供者（在主 composer.json 中，然后在 config/app.php [provider & alias] 中），然后运行
composer dump-autoload - 确保您已启动您的包：转到文件夹，然后
composer init - 尝试
php artisan config:cache或删除所有内容bootstrap/cache/

After adding the dependency in composer.json, you have to install the package before adding the class in service provider, using the below command:
在 composer.json 中添加依赖项后，您必须在服务提供者中添加类之前安装包，使用以下命令：
composer update
You can easily check if the physical file(NotificationServiceProvider) exists in your project. If it does not exists, you need to install the package using above command(don't forget to comment out the service provider declaration in app.php and re-enable after installing the package.)
您可以轻松检查项目中是否存在物理文件（NotificationServiceProvider）。如果不存在，则需要使用上述命令安装该包（不要忘记在app.php中注释掉服务提供者声明并在安装该包后重新启用。）
