ModelAndView in spring

[cool_zephyr]

Hello everyone..i'm trying to use spring to develop a website..but I am stuck with this snippet..what is the difference between

@RequestMapping(value="/addBook",method=RequestMethod.GET)
    public ModelAndView Login() {
        ModelAndView model=new ModelAndView("addBook");
        return model;
    }

and this

@RequestMapping(value="/addBook",method=RequestMethod.GET)
    public String Login() {
        return "addBook"
    }

I'm really confused with this..don't both of them do the same job?? if not, could anyone please explain me.

I'm no familiar with JSP Framework. I think there are different in term of how you used it.
