MVC Routes and Controllers architecture with multiple versions using Spark

Question

I am implementing a Rest API in Java using the framework Spark. I need to split the routes into two versions or more: v1 and v2. I know the Spark provides the path(), I believe it is not difficult.

My question is on how to perform folder structure based on MVC template.

Note: I commented on Spark because of the context of the framework I’m using.
