Controller Class Exists But Not Found

Question

For some reason, the target controller class is not found even though it already exists in the correct path.

Route

Route::post('/send', 'MailController@send');

My controller path is App->Http->Controllers

Here is my controller:

<?php
namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Mail;
use App\Mail\SendMail;

class MailController extends Controller{
    function index() {
        ...
    }
    function send(Request $request) {
        ...
    }
}

I have already tried composer dump-autoload. I was using laravel framework 8.0 so I have also tried to revert and use 7.24. Still, target class is not found.

change to `Route::post('/send', [MailController::class, 'send']);` — STA, Sep 13 '20 at 06:42
Where are you defining that route? Does `Route::post('/send', '\App\Http\Controllers\MailController@send')` work any better? — apokryfos, Sep 13 '20 at 06:42

In Laravel 8, $namespace property with a value of App\Http\Controllers is set to null by default, So need to define :

Change :

Route::post('/send', 'MailController@send');

to,

use App\Http\Controllers\UserController;

Route::post('/send', [MailController::class, 'send']);

Or, Using string syntax :

Route::get('/users', 'App\Http\Controllers\MailController@send');
