You have requested a non-existent service "user_service" - php

Question

Iam trying to implement service for encoding password but it seems it doesn't work cause I get "You have requested a non-existent service user_service " error.
Here is my code :
Vendor/BundleNameBundle/Resources/config/services.yml
services:
user_service:
class: Morescreens\VideomanagerBundle\Service\UserService
arguments: ['#security.encoder_factory']
app/config/config.yml
imports:
- { resource: "#morescreensVideomanagerBundle/Resources/config/services.yml" }
code for my service
class UserService {
/**
* #var EncoderFactoryInterface
*/
private $encoderFactory;
public function __construct(EncoderFactoryInterface $encoderFactory)
{
$this->encoderFactory=$encoderFactory;
}
public function setEncodedPassword(User $user)
{
$encoder=$this->encoderFactory->getEncoder($user);
$password=$encoder->encodePassword($user->getPassword(),$user->getSalt());
$user->setPassword($password);
}
}
Inside mine controller:
$user=new User();
$user->setPassword('password');
$this->get('user_service')->setEncodedPassword($user);
EDIT:
I manually deleted cache folder and my service started to work.

Try looking at your src/{VendorName}/{BundleName}Bundle/DependencyInjection/{VendorName}{BundleName}Extension.php
This file should load your service definitions like this:
<?php
namespace Vendor\{BundleName}Bundle\DependencyInjection;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\Config\FileLocator;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader;
/**
* This is the class that loads and manages your bundle configuration
*
* To learn more see {#link http://symfony.com/doc/current/cookbook/bundles/extension.html}
*/
class Vendor{BundleName}Extension extends Extension
{
/**
* {#inheritDoc}
*/
public function load(array $configs, ContainerBuilder $container)
{
$configuration = new Configuration();
$config = $this->processConfiguration($configuration, $configs);
//Load our YAML resources
$loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
$loader->load('services.yml');
}
}
This will load the service definition from src/{VendorName}/{BundleName}Bundle/Resources/config/services.yml into the container. If that still doesn't work try doing php app/console cache:clear. For speed reasons, symfony will basically aggregate all your service (and other configuration files) into a cached file so it doesn't have to read those files every time. The files that actually cache the service definitions are located:
app/cache/{envName}/ (The cache directory can be configured to be located wherever you want, this is just the default).
The files that have the relevent info for container service definitions are:
app{EnvName}DebugProjectContainer.php
app{EnvName}DebugProjectContainer.php.meta
app{EnvName}DebugProjectContainer.xml
