    @Controller
@RequestMapping("/author")

    }

    @RequestMapping(method = RequestMethod.GET)
    public String get(Model model) {
        return "author-list";
    }

    @RequestMapping(value = "/new", method = RequestMethod.GET)
    public String create(Model model) {
        model.addAttribute("author", new Author());
        return "author-form";

    public String createPost(@ModelAttribute("author") Author author,
            BindingResult result) {
        new AuthorValidator().validate(author, result);
        if (result.hasErrors()) {
            return "author-form"; …
