@RequestMapping(value = "/save", method = RequestMethod.POST)
public ModelAndView saveArticle(@ModelAttribute(" article ") Article article,
BindingResult result) {
ModelAndView modelAndView = new ModelAndView();

modelAndView.addObject("user_sess",article.getUser ());
System.out.println("article.getUser()"+article.get User());
articleService.addArticle( article);

// session.setAttribute("user_Sess", article.getUser());
// return new ModelAndView("redirect:/articles.html");
return new ModelAndView("Welcome");
}

@RequestMapping(method = RequestMethod.GET)
public ModelAndView listArticles() {
Map<string,> model = new HashMap<string,>();
model.put("articles", articleService.listArticles());

return new ModelAndView("articlesList", model);
}

@RequestMapping(value = "/add", method = RequestMethod.GET)
public ModelAndView addArticle(@ModelAttribute("article") Article article,
BindingResult result) {
return new ModelAndView("addArticle");
}
}
