ZF2 check if user logged in other modules

Guys how can i check in other modules if user is logged or not? Can i do that with sessions or Zend\Auth have better way to do that?

I created auth module using Zend \ Authentication component and evrything work fine.

I want separate my modules like this:

• Auth Module
• Custrommer Module
• Order Module
• Admin Module

No how with my existing Auth Module i can check in Admin, Order and Custommer modules if user logged or not? Does i need to create specific service for that?

I dont have to much expiriance with ZF, am in learing phase.

Any example and advice?

Check my answer here https://stackoverflow.com/a/32392608/949273

$events->attach(MvcEvent::EVENT_ROUTE, __CLASS__ . '::checkPermission', -100);

Basically in every request I execute

public static function checkPermission(MvcEvent $e)
{
    $auth = $e->getApplication()->getServiceManager()->get('Zend\Authentication\AuthenticationService');

    if(!$auth->hasIdentity()){
        $url      = $e->getRouter()->assemble([], ['name' => 'login']);
        $response = $e->getResponse();
        $response->getHeaders()->addHeaderLine('Location', $url);
        $response->setStatusCode(302);
        $response->sendHeaders();

        return $response;
    }
}
