title: Symfony 3 use parameters in class that is not a service
body: <p>I have a service that instantiates other classes.</p>
  
  <p>I would like to parametrize a <code>$url</code> variable in those classes (different URL by class).</p>
  
  <p>How could I access a parameter from a class that is not a service?</p>
  
  <p>I could make those classes a service, but it would only be because of parameters, because they should not be stand alone services.</p>
  
  <p>How could I solve this?</p>
