'Laravel 8: Target class [ProductController] does not exist

I'm using Laravel-8 to develop my project, and I have a resource controller named ProductController which is placed at Admin directory inside Controllers, just like this image is showing:

capture

Then at my route file, I coded this:

Route::resource('products', 'ProductController');
Route::resource('permissions', 'PermissionController');

But when I want to go to products route, I get this message:

Illuminate\Contracts\Container\BindingResolutionException Target class [App\Http\Controllers\Admin\ProductController] does not exist.

Now you may say in Laravel-8, I have to use Route::get('/', ProductController::class);, but as you can see above, I have also determined a permissions route to PermissionController by the old method and it is working completely fine!

The namespace of Admin is also specified at RouteServiceProvider:

Route::middleware(['web' , 'auth' , 'auth.admin'])
                ->namespace('App\Http\Controllers\Admin')
                ->prefix('admin')
                ->group(base_path('routes/web/admin.php'));

Note that I also tried Route::resource('products', ProductController::class); , but still get the same error.

I guess the issue is coming from another part!

So if you have any idea about this, please let me know, I would really appreciate any idea or suggestion from you guys...

Thanks in advance.

UPDATE #1:

ProductController goes like this:

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Models\Product;

Solution 1:[1]

Inside your ProductController, you need to have namespace like this

namespace App\Http\Controllers\Admin;

Solution 2:[2]

You just need go to app/Http/Providers/RouteServiceProvider.php

uncomment: protected $namespace = 'App\Http\Controllers';

enter image description here

You need to declare your namespace:

use App\Http\Controllers\Admin\ProductController;

Then on your route:

Route::apiResource('products', ProductController::class);

Not sure whether this answer would help anyone or not but, I think you haven't imported the ProductController into your api.php

There are two widely used ways to import in laravel:

1st way- As @Talita suggested, import the file with the use syntax and then call out the class in Route::apiResource

use App\Http\Controllers\Admin\ProductController;

Route::apiResource('products', ProductController::class);

2nd way- You can call the class's location within the Route::apiResource just as follows-

Route::apiResource('/products', '\App\Http\Controllers\Admin\ProductController');

Solution 5:[5]

you should remove line use namespace... controller in route page.

Solution 6:[6]

I think you forget to Commit the transaction, like this

btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            FragmentActivity fragment = new DeterminaFrag();
            FragmentManager fragmentManager = fragment.getSupportFragmentManager();
            fragmentManager.beginTransaction().replace(R.id.nav_host_fragment_content_main, fragment);
            fragmentManager.commit();

        }
    });

I hope it's can help your problem
