If you wanna compare Spring MVC with struts consider below benefit of Spring MVC over Struts    Spring provides a very clean division between controllers  JavaBean models  and views   Spring s MVC is very flexible  Unlike Struts  which forces your Action and Form objects into concrete inheritance  thus taking away your single shot at concrete inheritance in Java   Spring MVC is entirely based on interfaces  Furthermore  just about every part of the Spring MVC framework is configurable via plugging in your own interface  Of course we also provide convenience classes as an implementation option   Spring  like WebWork  provides interceptors as well as controllers  making it easy to factor out behavior common to the handling of many requests   Spring MVC is truly view-agnostic  You don t get pushed to use JSP if you don t want to  you can use Velocity  XLST or other view technologies  If you want to use a custom view mechanism - for example  your own templating language - you can easily implement the Spring View interface to integrate it   Spring Controllers are configured via IoC like any other objects  This makes them easy to test  and beautifully integrated with other objects managed by Spring   Spring MVC web tiers are typically easier to test than Struts web tiers  due to the avoidance of forced concrete inheritance and explicit dependence of controllers on the dispatcher servlet   The web tier becomes a thin layer on top of a business object layer  This encourages good practice  Struts and other dedicated web frameworks leave you on your own in implementing your business objects  Spring provides an integrated framework for all tiers of your application

Spring s Web MVC framework is designed around a DispatcherServlet that dispatches requests to handlers  with configurable handler mappings  view resolution  locale and theme resolution as well as support for upload files  The default handler is a very simple Controller interface  just offering a ModelAndView handleRequest request response  method  This can already be used for application controllers  but you will prefer the included implementation hierarchy  consisting of  for example AbstractController  AbstractCommandController and SimpleFormController  Application controllers will typically be subclasses of those  Note that you can choose an appropriate base class  if you don t have a form  you don t need a form controller  This is a major difference to Struts

The main difference between struts  amp  spring MVC is about the difference between Aspect Oriented Programming  AOP   amp  Object oriented programming  OOP     Spring makes application loosely coupled by using Dependency Injection The core of the Spring Framework is the IoC container    OOP can do everything that AOP does but different approach  In other word  AOP complements OOP by providing another way of thinking about program structure    Practically  when you want to apply same changes for many files  It should be exhausted work with Struts to add same code for tons of files  Instead Spring write new changes somewhere else and inject to the files   Some related terminologies of AOP is cross-cutting concerns  Aspect  Dependency Injection
