 @Controller
@RequestMapping("/welcome")
public class WelcomeController {

    @RequestMapping(value = "/index")
    public ModelAndView welcomeIndex(HttpServletRequest request) {

    String param = request.getParameter("param");
    if("1".equals(param)) {
        ModelAndView mav = new ModelAndView("index");
        return mav;
    } else {
        ModelAndView mav = new ModelAndView("welcome.index.def");
        return mav;
    }
