BindingResult和bean名称'mstUsermaster'的普通目标对象都不可用作请求属性

I am trying a login process using jstl taglib. Below is my controller portion code

@SuppressWarnings("unused")
    @RequestMapping(value = "/authentication", method = RequestMethod.POST)
    public String login(@ModelAttribute("mstUsermaster")MstUsermaster mstUsermaster, BindingResult bindingResult, Model model) {

    MstUsermaster usermaster=loginService.authenticateUser(mstUsermaster);

    if(mstUsermaster != null ){
        System.out.println("You Are a Valid User "+mstUsermaster.getName());
        model.addAttribute("mstUsermaster1",usermaster);

    }else{
        model.addAttribute("loginMessage", "You have entered Wrong UserName or Password!");
        return "index";
    }
    return "dashboard";
}
