Change url path in Spring MVC by @RequestMapping

Currently path is showing

http://localhost:8081/UserLogin/login

But i want this as

http://localhost:8081/UserLogin/index
or
http://localhost:8081/UserLogin/

My controller class is

@RequestMapping(value = "/login" ,method = RequestMethod.POST)
  public ModelAndView test(HttpServletRequest request, HttpServletResponse response) {
      //return "hi this is a test";
      String userName = request.getParameter("data[Admin][user_name]");
      String userPass=request.getParameter("data[Admin][password]");
      int userId=userDAO.getUser(userName, userPass);
      if(userId!=0){  
        String message = "welcome!!!"; 
        return new ModelAndView("result", "message", message);  
      }  
      else{  
        String message = "fail";
        return new ModelAndView("index", "message",message);  
      } 
  }

Want to change in else condition when not match. Thanks in advance. :)
