Solved - Target class [ProductController] does not exist in Laravel 8

If you need to see example of target class clearance does not exist laravel 8. you will learn Target controller class does not exist laravel 8. step by step explain target class does not exist laravel 8. I’m going to show you about laravel 8 Target class [Controller] does not exist.

Just yesterday launch laravel 8 and i was trying to create my first application with laravel 8 and when i create controller call ProductController and when i used with route then i found following issue:

"Target class [ProductController] does not exist"

you can see bellow screenshot too.

Actually this is not an error but laravel 8 removed default namespace form RouteServiceProvider.php file. but i will say this good feature if you want to call your controller class from different namespace.

but now if you want to looking for solution then i will give you two solution. you can use in route file or you can define default namespace on RouteServiceProvider.php file. let's see both solution one by one.

I hope it can help you.

Solution 1: Use on Route File

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
use App\Http\Controllers\ProductController;
use App\Http\Controllers\PostController;
  
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
  
Route::get('/', function () {
    return view('welcome');
});
  
Route::resource('products', ProductController::class);
  
Route::get('posts', [PostController::class, 'index']);

Solution 2: Define in RouteServiceProvider

second solution is you can define as laravel old version. so let's define it as bellow:

app/Http/Providers/RouteServiceProvider.php

<?php
  
namespace App\Providers;
  
use Illuminate\Cache\RateLimiting\Limit;
use Illuminate\Foundation\Support\Providers\RouteServiceProvider as ServiceProvider;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\RateLimiter;
use Illuminate\Support\Facades\Route;
  
class RouteServiceProvider extends ServiceProvider
{
    /**
     * The path to the "home" route for your application.
     *
     * This is used by Laravel authentication to redirect users after login.
     *
     * @var string
     */
    public const HOME = '/home';
    protected $namespace = 'App\Http\Controllers';
  
    /**
     * Define your route model bindings, pattern filters, etc.
     *
     * @return void
     */
    public function boot()
    {
        $this->configureRateLimiting();
  
        $this->routes(function () {
            Route::middleware('web')
                ->namespace($this->namespace)
                ->group(base_path('routes/web.php'));
  
            Route::prefix('api')
                ->middleware('api')
                ->group(base_path('routes/api.php'));
        });
    }
  
    ....

routes/web.php

<?php
  
use Illuminate\Support\Facades\Route;
  
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
  
Route::get('/', function () {
    return view('welcome');
});
  
Route::resource('products', 'ProductController');
  
Route::get('posts', 'PostController@index');

I hope it can help you...
