Symfony2: How to inject ALL parameters in a service?

Question

How can I inject ALL parameters in a service?

I know I can do: arguments: [%some.key%] which will pass the parameters: some.key: \"value\"

It is not a good practice to inject the entire Container into a service. Also if you have many parameters that you need for your service it is not nice to inject all of them one by one to your service. Instead I use this method:

1) In config.yml I define the parameters that I need for my service like this:

 parameters:
    product.shoppingServiceParams:
        parameter1: 'Some data'
        parameter2: 'some data'
        parameter3: 'some data'
        parameter4: 'some data'
        parameter5: 'some data'
        parameter6: 'some data'

2) Then I inject this root parameter to my service like:

services:
  product.shoppingService:
    class: Saman\ProductBundle\Service\Shopping
    arguments: [@translator.default, %product.shoppingServiceParams%]

3) In may service I can access these parameters like:

namespace Saman\ProductBundle\Service;

use Symfony\Bundle\FrameworkBundle\Translation\Translator;

class Shopping
{   
    protected $translator;
    protected $parameters;

    public function __construct(
        Translator $translator, 
        $parameters
        ) 
    {
        $this->translator = $translator;
        $this->parameters = $parameters;
    }

    public function dummyFunction()
    {
        var_dump($this->getParameter('parameter2'));
    }

    private function getParameter($key, $default = null)
    {
        if (isset($this->parameters[$key])) {
            return $this->parameters[$key];
        }

        return $default;
    }  
}

4) I can also set different values for different environments. For example in config_dev.yml

 parameters:
    product.shoppingServiceParams:
        parameter1: 'Some data for dev'
        parameter2: 'some data for dev'
        parameter3: 'some data for dev'
        parameter4: 'some data for dev'
        parameter5: 'some data for dev'
        parameter6: 'some data'
