In your Module.php file, add the following  

  public function getServiceConfig()
    {
        return array(
            'factories' => array(
                'article_mapper' => function ($sm) {
                    return new \Article\Modele\ArticleTable(
                        $sm->get('Doctrine\ORM\EntityManager')
                    );
                },
            ),
        );
    }

# Then, in you controller, you can get the mapper as follow:

$articleMapper = $this->getServiceLocator()->get('article_mapper');
$articleMapper->createArticle($data['name'],$data['subject'],$data['email'],$data['message']);


# The ArticleTable class become:

use Doctrine\ORM\EntityManager as EntityManager;

class ArticleTable {
   
    protected $em;

    public function __construct(EntityManager $entityManager) {
        $this->em = $entityManager;
    }
   
    public function createArticle($name,$subject,$email,$message)
    {
       
        $article = new ArticlesNew();
       
        $article->setContent($message);
       
        $article->setDate(new \DateTime('NOW()'));
        $article->setIdAuthor($name);
        $article->setTitle($subject);
        $this->em->persist( $article);
        $this->em->flush();
    }
}
