Migration from ZF2 to ZF 3 without getServicelocator(); - php

Question

I am new at ZF3 and I need your help.
In ZF3 there is no service Locator any more. So I created a Factory class to replace the service Locator in my code.
Here is my code with service Locator in my AbstractController.php file:
protected function getService()
{
return $this->getServiceLocator()->get($service); //remove from ZF3
return $this->service = $service;
}
Now I replaced the service Locator in AbstractController.php:
protected function getService($service)
{
$service = $this->service;
return $this->service = $service;
}
And in Module.Config.php I added the following lines:
return [
'controllers' => [
'factories' => [
Controller\AbstactController::class => Controller\AbstactControllerFactory::class,
],
],
And I created a AbstractControllerFactory file with the following lines:
<?php
namespace Application\Controller;
use Application\Controller\AbstractController;
use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;
class AbstractControllerFactory implements FactoryInterface
{
protected function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
return new AbstractController($container->get(service::class));
}
}
I need to know if this is a correct migration from ZF2 to ZF3?

In ZF3 the first thing you do is create your Service and a Factory for it. Let's take in this example UserManager.php in Services folder.
So we have in folder Service -> UserManager.php and in Service -> Factory -> UserManagerFactory.php
UserManagerFactory.php:
<?php
namespace User\Service\Factory;
use Interop\Container\ContainerInterface;
use User\Service\UserManager;
/**
* This is the factory class for UserManager service. The purpose of the factory
* is to instantiate the service and pass it dependencies (inject dependencies).
*/
class UserManagerFactory
{
/**
* This method creates the UserManager service and returns its instance.
*/
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
$entityManager = $container->get('doctrine.entitymanager.orm_default');
return new UserManager($entityManager);
}
}
UserManager.php:
<?php
namespace User\Service;
use User\Entity\User;
/**
* This service is responsible for adding/editing users
* and changing user password.
*/
class UserManager
{
/**
* Doctrine entity manager.
* #var Doctrine\ORM\EntityManager
*/
private $entityManager;
/**
* Constructs the service.
*/
public function __construct($entityManager)
{
$this->entityManager = $entityManager;
}
// REST OF YOUR CODE
}
Now that we have our service, we go into User\config\modules.config.php:
'service_manager' => [
'factories' => [
Service\UserManager::class => Service\Factory\UserManagerFactory::class,
],
],
Well that's basically it, we can inject the service in our controller and job done:
<?php
namespace User\Controller;
use Zend\Mvc\Controller\AbstractActionController;
/**
* This controller is responsible for user management (adding, editing,
* viewing users and changing user's password).
*/
class UserController extends AbstractActionController
{
/**
* User manager.
* #var User\Service\UserManager
*/
private $userManager;
/**
* Constructor.
*/
public function __construct($userManager)
{
$this->userManager = $userManager;
}
// REST OF YOUR CODE
}
I really hope this helps you understand how to use Service in ZF3.
Good Luck!
