Spring MVC controller

[Jack Mutansan]

@RequestMapping(value="/getNames")
public ModelAndView getNames(ModelAndView mv) {
...
...
}

above is a typical control code.  But I saw some older version spring code like

public ModelAndView processCancel(HttpServletRequest req, HttpServletResponse resp, Object command, BindException ex) {

..
}

above is from book "Spring REceipes A problem-solution approach" by Gary Makin 2008.  A very old book.

But  old version seems making more sense to me since it takes request/response as input.  The new version directly takes a ModelAndView as input , where does it get request and response ?
