How to reuse a Service Layer in Zf2? - path

Question

I have a Service Layer for my A module. Now I want to reuse the Service Layer by calling it from another module B. I understand that I have to inject my Service Layer in Controller of Module B.
My question is how do I give the path of the Service Layer for module B?
In my Controller Factory for module B, $serviceLocator->get('A\Service\AService'), and in my Controller, use A\Service\AService; these won't work as these are directory locations for module A.Also, It seems like default path starts from folder outside controllers. How do I use these path for B?
class IndexController extends AbstractActionController
{
function __construct(AService $sm) {
$this->sm =$sm;
}
public function indexAction()
{
$event = $this->getEvent();
$request = $event->getRequest();
$router = $event->getRouter();
$uri = $router->getRequestUri();
$baseUrl = sprintf('%s://%s%s', $uri->getScheme(), $uri->getHost(), $request->getBaseUrl());
$this->sm->callMethod($baseUrl);
}
}
My module.config.php,
return array(

Answer 1

It should works the same as using the Service in A controller.
I assume that you register service in module A
...
'invokables' => array(
'A\Service\AService' => 'A\Service\AService',
)
...
From that point you can use it in any module (eg. in your B modul Module.php):
public function getControllerConfig()
{
return array(
'factories' => array(
'B\Controller\Index' => function ($sm){
$a = $sm->getServiceLocator()->get('A\Service\AService');
return new B\IndexController($a);
}
),
);
}
