Spring is getting towards more annotation style of coding. It introduces the @Controller annotation to define controllers. If you use this annotation, you don't need to extend any of the controller classes. This annotation was there in 2.5, but the Spring team has decided to deprecate the classes in 3.0, to favor the MVC annotations.

Thanks for your reply.

what do we gain from this annotation kind of coding other than easing the development or coding?

isn't it difficult to find out the project information if everything in mvc is annotated?

I would prefer to use application context xml in this case.. because that gives the good idea about how the MVC flow in my application.

Could you tell me why annotation style is preferred over xml configuration?

I agree Spring has still a long way to go for stabilization. The web services front, I tried code from the tutorials and books and looks like the methods don't even exist any more!!

But talking about annotations, Spring recommends annotations over XML configuration

In case anybody is interested, there is a video called "Spring Framework 3.0, The Next Generation" on the excellent InfoQ website, introducing some of the new features in Spring 3 and relating them to Spring 2.5 and Java 5/6. The video is an hour and 15 minutes long, so get yourself a cup of coffee and make yourself comfortable!


No more Blub for me, thank you, Vicar.
