A @Controller is a more flexible way to define a form / wizard. You are supposed to map methods to requests based on requested path / request parameters / request method. So instead of defining a list of views and processing the request based on some required "step" parameter, you can define the steps of your wizard as you wish (also the command object will be handled more transparently).
Here's how you can get to emulate a classic AWFC functionality (this is only meant to be an example, there's a lot more you can do).
