为什么我尝试使用自定义用户提供程序登录时出现“Class App \ Listeners \ LogAuthenticationAttempt不存在”错误?

I am pretty new in PHP and Laravel framework and I am going crazy trying to implement the following task.

I am trying to follow this tutorial to implement a custom user provider:

https://blog.georgebuckingham.com/laravel-52-auth-custom-user-providers-drivers/

I am using Larave 5.3 version.

I briefly expain what I need: my Laravel application is only a front end application, all the business logic, included the user authentication, is performed by a Java back end application that exposes REST web services.

Performing a call to:

http://localhost:8080/Extranet/login

and passing username and password as basic authentication I obtain a JSON response like this that represent the logged user:

{
  "userName": "Painkiller",
  "email": "painkiller@gmail.com",
  "enabled": true
}

So, in my Laravel application, I have to perform this call and then parse the previous returned JSON object to generate the authenticated object into the front end application session.

I think that the previous custom user provider is the neater and most natural solution to do it, but I am obtaining an erro, I will explain the situation.

I have implemented all the 4 steps of the previous tutorial and I think that I have correctly replaced the user provider with my custom user provider.

Aftere these implementation steps I performed this command:

php artisan make:auth

to generate te view and the routes related to the Laravel login system. I expect that it is using the custom user provider defined by me.

So I have these routes:

$ php artisan route:list

As you can see there are the standard login routes. I think that now it have to use my custom user provider (the one that call my REST web service) instead the standard one.

I run the application using the statment:

php artisan serve

It starts without no error, then I access to this URL:

http://localhost:8000/login

and the login page is correctly displayed.

Then i insert the credential (e-mail and password) but when I submit the login form I obtain this error message:

Why? What could be wrong? How can I try to ix this issue?

I am not into Laravel but searching online information about Laravel login and the problem to the missing LogAuthenticationAttempt class I have fount this SO post:

Log failed login attempts with Laravel 5.2

Maybe it is a similar problem but I am not understanding it it could be the same situation and how to solve it.

What can I do?

    Try running the command php artisan event:generate and it will generate any events in the $listen variable in your EventServiceProvider.php file.
