The rationale is that this is a very common task and we can't expect non-advanced users to have to remember what the fully-qualified
class name of the Exception is in order to use it.
Some question whether or not the base Controller should be included at all. I think it absolutely must be included because it's important for beginners and for rapid development of smaller features/applications (and rapid development is good for beginners).
So, assuming that we *do* like the base Controller, we should really use it to its fullest potential - making the lives of developers as easy as possible.
The Response is not available in the DIC anymore.
When you need to create a response, create an instance of
Symfony\Component\HttpFoundation\Response instead.
As a side effect, the Controller::createResponse() and Controller::redirect()
methods have been removed and can easily be replaced as follows:
return $this->createResponse('content', 200, array('foo' => 'bar'));
return new Response('content', 200, array('foo' => 'bar'));
return $this->redirect($url);
return Response::createRedirect($url);
A Controller must now implements ControllerInterface.
The BaseController can be used as the base class for Controllers.
The Controller class adds some proxy methods and an array access to the Container.
