Struts 1 reached end of life so I'm going to assume you are talking about Struts 2. (Struts 1 and 2 are really different frameworks.) This article describes some differences between Spring MVC and Struts 2.
Note that people just say "Struts" and not "Struts MVC" even though it is a MVC framework. With Spring, you have to say MVC because Spring is already the main framework.
