Localizing Exception Messages with Spring

I want to localize exception messages from POJO classes using Spring. I have a Spring MVC application through which I can add books. If the name of the added book is null, the implementation class throws an exception. I want to localize this.

I know that I can use localeResolvers in JSP pages, and I already did it. Can I use this to collect localized error messages in POJO? If so, how can I insert a language language editor (Cookie or Session) or the locale that was set in Cookie / Session into the POJO class?

addBook method browser exception

    public void addBook(IBook book) throws Exception {
    if (book.getTitle() == null || book.getTitle() == "") {
        throw new Exception("Title is null");
    }

I want to throw new Exception("Title is null"); be something like

String msg = rBundle.getMessage(propKey)
throw new Exception(msg);

rBundle - , , propKey

,

@RequestMapping(method = RequestMethod.POST)
public String processSubmit(
        @RequestParam("siteLanguage") String siteLanguage,
        @ModelAttribute("book") Book book, BindingResult result,
        SessionStatus status, HttpServletRequest arg0) {
    logger.debug("Adding a Book");
    Locale loc = RequestContextUtils.getLocale(arg0);

    if (result.hasErrors()) {
        return "error.htm";
    } else {
        try {
            Author author = new Author("Gabriel Garcia Marquez");
            book.setAuthor(author);
            library.addBook(book);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return "redirect:home.htm";
    }
}
