Question

Is there any difference in using annotation routes or group routes in symfony 2 when it comes to performance, convenience, maintainability or in any aspect that would make the other more advisable to use?

Answer 1

Use SensioFrameworkExtraBundle, already shipped with Symfony 2. Having route names and paths in the same place of controller action is the right way to go. If you want to modify a path or action name simply go to that action, without editing routing.yml.

Then give a name to your “grouped routes” e.g. bundle_controller pattern or maybe bundle_entity (if controller is used for CRUD on a single entity):

# app/config/routing.yml
acme_hello_my_annotated_controller:
    resource: "@AcmeHelloBundle/Controller/MyAnnotatedController.php"
    type: annotation

Eventually prefixing all paths defined by annotations (add prefix: /my/path/prefix).

EDIT: don’t know anything about performances. I’m talking only about convenience.
