Laravel 5 , understand the services and containers - laravel-5

Question

I would like to apply the best laravel practices regarding the services + containers.
Usually when I need to use a method anywhere in my app, I do that :
class PersonneController extends Controller {
private $personne_service;
private $role_service;
public function __construct() {
$this->personne_service = new PersonneService();
$this->role_service = new RoleService();
}
/**
* Renvoi la liste des personnes d'une école de la personne connectée
* #return
*/
public function getListePersonnes(Request $request, $id_ecole = null)
{
if ($id_ecole == null){
$id_ecole = Auth::user()->id_ecole;
}
$liste_personnes = $this->personne_service->getListePersonnesMultiRecherches($request->all());
See the last line to use a method in an other class. It works fine and I have understood the mechanic !
Now I would like to do the same thing using services and containers. Here what I do :
step 1 : create a service provider
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use App\Services\PersonneService;
class PersonneServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* #return void
*/
public function boot()
{
//
}
/**
* Register the application services.
*
* #return void
*/
public function register()
{
$this->app->bind('PersonneService', function ($app) {
return new App\Services\PersonneService();
});
}
}
step 2 : declare this container into my app/config file :
'providers' => [
// ....
App\Providers\PersonneServiceProvider::class,
],
step 3 : i use this method anywhere in my app. For example in a controller :
(see the commented lines vs the previous code)
class PersonneController extends Controller {
// private $personne_service;
private $role_service;
public function __construct() {
// $this->personne_service = new PersonneService();
$this->role_service = new RoleService();
}
/**
* Renvoi la liste des personnes d'une école de la personne connectée
* #return
*/
public function getListePersonnes(Request $request, $id_ecole = null)
{
if ($id_ecole == null){
$id_ecole = Auth::user()->id_ecole;
}
// $liste_personnes = $this->personne_service->getListePersonnesMultiRecherches($request->all());
$personne_service = app()->make('PersonneService');
$liste_personnes = $personne_service->getListePersonnesMultiRecherches($request->all());
It does not work. I have this error :
Class PersonneService does not exist
in Container.php (line 729)
My questions :
what are the problems ? (I read the official doc + a lot of tutorials on this topic)
is it really a good practice to do that ? or do you think that my first technich is well too ?
Thanks for your feedbacks. Merci
