hi Monica. Shiralkar,
No its not necessary that every time you should return ModelAndView object. you can also return Map or List.
(which will be accounted as view name).
Suppose you are doing Ajax call to controller and you want list of objects returned from controller than you need to put @RequestMapping annotation(if you are using Spring MVC 3.0 or above) before controller method name that you want to call.
It is sorta covered in the
JavaRanch Style Guide
subject: is it necessary that method of Controller Class of Spring should return a Model and View Object?
One view/controller, pluggable models
different approaches to MVC
Decoupling the GUI
Spring MVC 3.0 Controller Unit testing
Spring MVC -- where does the model code go?
