Symfony 2 dependency injection into the Controller construct

Question

I've tried to add many services into the construct of a Controller without success.

class PersonController extends Controller
{
    public function __construct(UtilityService $Utils)
    {
        $this->util = $Utils;
    }

    public function indexAction()
    {
        ...
    }

}

what's the path I must follow?

You need define your controller PersonController as a service — Victor Bocharsky

You need to define your PersonController controller as a service in services.yml and inject to them UtilityService:

# src/Acme/HelloBundle/Resources/config/services.yml
parameters:
    # ...
    person.controller.class: Acme\HelloBundle\Controller\PersonController

services:
    person.controller:
        class: "%person.controller.class%"
        arguments: ["@UtilityService"]

Where:

person.controller.class is a name of your controller class
UtilityService in arguments is a name of servicem which you want to inject

as @Cerad mention in this post:

The trick is to define your controllers as services and then use the service id instead of the class name.

This is not a complete answer, you can not just insert a link to documentation

Also this just mentions another answer. Not really fair to @Victor

sorry if you think otherwise but I don't see the point to duplicate the answer. Even considering this is what he needs. It's clear, quickly and good enough for it purpose
