Migrating from Struts2 to Spring MVC

Question

Scenario: A fairly mature project uses Struts2 and Spring and Hibernate. I say mature because it has been going on a for a while and there are many struts actions written al

Answer 1

I have to ask: What advantages do you see with Spring MVC that aren't being fulfilled by Struts 2?
If there's not at least a handful of "smoking hot" features, or the amount of time saved is more than enough to overcome the time taken for the migration in the first place then it's probably best to stick with what you have.
