A simple library that provides autowiring for the Symfony2 Dependency Injection (DI) container.
This bundle supports constructor autowiring only, see http://springindepth.com/book/in-depth-ioc-autowiring.html for description.

- Install via composer:
composer require kutny/autowiring-bundle- Add KutnyAutowiringBundle to your application kernel
// app/AppKernel.php
public function registerBundles()
{
return array(
// ...
new Kutny\AutowiringBundle\KutnyAutowiringBundle(),
// ...
);
}In most cases this bundle does not require any configuration. However if your app fails to start after installing this bundle giving you Kutny\AutowiringBundle\Compiler\CannotResolveParameterException, you may need to remove some services from autowiring. See example bellow:
Example 1:
You are receiving Kutny\AutowiringBundle\Compiler\CannotResolveParameterException with message like "Class Thrace\FormBundle\Form\Type\Select2Type (service thrace_form.form.type.select2), parameter $widget".
The problem is that Thrace\FormBundle\Form\Type\Select2Type service definition does not contain explicit $widget argument definition. It is very likely that the Thrace\FormBundle developer just forgot to define the $widget argument. KutnyAutowiringBundle expects all services to have all arguments defined (or have default values). As a result we have to disable autowiring for the thrace_form.form.type.select2 service by adding it (as a regular expression) among ignored_services:
kutny_autowiring:
ignored_services: ['thrace_form\.form\.type\.select2']
If you run into problems with more services from the Thrace\FormBundle bundle (thrace_form.form.type.select2, thrace_form.form.type.recaptcha, ...), you can easily add the whole "service namespace" to ignored_services using the following reqular expression:
kutny_autowiring:
ignored_services: ['thrace_form\.form\.type.*']
Sample controller with service autowiring (controller itself is also defined as service):
namespace Acme\DemoBundle\Controller;
use Acme\DemoBundle\Facade\ProductsFacade;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
/**
* @Route(service="controller.products_controller")
*/
class ProductsController
{
private $productsFacade;
public function __construct(ProductsFacade $productsFacade)
{
$this->productsFacade = $productsFacade;
}
/**
* @Route("/", name="route.products")
* @Template()
*/
public function productsAction()
{
return array(
'products' => $this->productsFacade->getProducts()
);
}
}Services configuration in app/config.yml:
services:
controller.products_controller:
class: Acme\DemoBundle\Controller\ProductsController
facade.products_facade:
class: Acme\DemoBundle\Facade\ProductsFacadeIn the following example, I've added:
- $productsPerPageLimit config option to ProductsController (must be wired manually)
- ProductsRepository manually wired with Doctrine2 EntityManager
<?php
namespace Acme\DemoBundle\Controller;
use Acme\DemoBundle\Facade\ProductsFacade;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
/**
* @Route(service="controller.products_controller")
*/
class ProductsController
{
private $productsPerPageLimit;
private $productsFacade;
public function __construct($productsPerPageLimit, ProductsFacade $productsFacade)
{
$this->productsPerPageLimit = $productsPerPageLimit;
$this->productsFacade = $productsFacade;
}
/**
* @Route("/", name="route.products")
* @Template()
*/
public function productsAction()
{
return array(
'products' => $this->productsFacade->getProducts($this->productsPerPageLimit)
);
}
}<?php
namespace Acme\DemoBundle\Facade;
use Acme\DemoBundle\Repository\ProductsRepository;
class ProductsFacade
{
private $productsRepository;
public function __construct(ProductsRepository $productsRepository) {
$this->productsRepository = $productsRepository;
}
public function getProducts($productsPerPageLimit) {
return $this->productsRepository->getProducts($productsPerPageLimit);
}
}<?php
namespace Acme\DemoBundle\Repository;
use Doctrine\ORM\EntityManager;
class ProductsRepository
{
private $entityManager;
public function __construct(EntityManager $entityManager) {
$this->entityManager = $entityManager;
}
public function getProducts($productsPerPageLimit) {
$query = $this->entityManager->createQueryBuilder()
->select('p')
->from('AcmeDemoBundle:Product', 'p')
->setMaxResults($productsPerPageLimit)
->getQuery();
return $query->getResult();
}
}Services config:

services:

arguments: [10, @facade.products_facade]
facade.products_facade:
