zf2: wie man Service Locator im Modell

Ich habe versucht, einige Ideen von anderen Beiträgen und Beispielen, aber ich habe immer noch keine Lösung.
Ich kann nicht erhalten die servicelocator in meinem Modell.

meine Module.php enthält die folgenden Fabrik in function getServiceConfig():

'Backend\Model\Beuser' => function($sm){
                     $serviceLocator = $sm->getServiceLocator();
                     return new \Backend\Model\Beuser($serviceLocator); 
               },

mein Modell Beuser.php sieht aus wie:

namespace Backend\Model;

use Zend\InputFilter\Factory as InputFactory;
use Zend\InputFilter\InputFilter;
use Zend\InputFilter\InputFilterAwareInterface;
use Zend\InputFilter\InputFilterInterface;


use Zend\ServiceManager\ServiceLocatorAwareInterface;
use Zend\ServiceManager\ServiceLocatorInterface;

class Beuser implements ServiceLocatorAwareInterface
{

    public $idx_be_user;
    public $be_user_email;
    public $be_user_password;
    public $be_user_firstname;
    public $be_user_lastname;
    public $be_user_phone;
    public $be_user_photo;
    public $be_user_shorttext;

     protected $inputFilter;    

     protected $serviceLocator;

    public function setServiceLocator(ServiceLocatorInterface $sl)
    {
        $this->serviceLocator = $sl;
        return $this;
    }

    public function getServiceLocator()
    {
        return $this->serviceLocator;
    }

    public function exchangeArray($data)
    {

        $this->idx_be_user          = (!empty($data['idx_be_user'])) ? $data['idx_be_user'] : null;
        $this->be_user_email        = (!empty($data['be_user_email'])) ? $data['be_user_email'] : null;
        $this->be_user_password  = (!empty($data['be_user_password'])) ? $data['be_user_password'] : null;
        $this->be_user_firstname = (!empty($data['be_user_firstname'])) ? $data['be_user_firstname'] : null;
        $this->be_user_lastname  = (!empty($data['be_user_lastname'])) ? $data['be_user_lastname'] : null;
        $this->be_user_phone        = (!empty($data['be_user_phone'])) ? $data['be_user_phone'] : null;
        $this->be_user_photo        = (!empty($data['be_user_photo'])) ? $data['be_user_photo'] : null;
        $this->be_user_shorttext = (!empty($data['be_user_shorttext'])) ? $data['be_user_shorttext'] : null;

    }

        }

        return $this->inputFilter;
    }

}

Aber
var_dump($this->getServiceLocator());
gibt NULL zurück. Das ist die reasion warum jeder Aufruf von $this->getServiceLocator()->get('something')
erstellt eine
PHP Fatal error: Call to a member function get()[...]

Könnten Sie mir helfen zu finden das problem?

PS: ich habe auch versucht, folgende Werk:
