CategoryService categoryService;
@Autowired
UserService userService;

@ModelAttribute("article")

    return new Article();
}

@RequestMapping("/admin/clanky")
public String articles(Model model){
    model.addAttribute("articles", articleService.findAll());
    model.addAttribute("categories", categoryService.findAll());
    model.addAttribute("users", userService.findAll());
    return "articles";
}

@RequestMapping(value="/admin/clanky", method=RequestMethod.POST)
public String saveArticle(@ModelAttribute("article") Article article, BindingResult result){
    Date publishDate = new Date();
    article.setPublishDate(publishDate);
    articleService.save(article);
    return "redirect:/admin/clanky.html?success=true";
}

@InitBinder
public void initBinder(WebDataBinder webDataBinder) {
    SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm");
    dateFormat.setLenient(false);
    webDataBinder.registerCustomEditor(Date.class, "publishDate",
            new CustomDateEditor(dateFormat, false));

Answer 1

在我看来，你正在使用Hibernate 3.x.如果是这种情况，我会确保您使用的是Hibernate核心版本3.6.10+。旧版本可能没有spring框架正在寻找的必要类定义。以下链接显示Hibernate 3.6.10具有您缺少的类定义：http://tool.oschina.net/uploads/apidocs/hibernate-3.6.10/org/hibernate/QueryTimeoutException.html

Answer 2

保存de object时遇到同样的错误。好吧这很奇怪，但显然hibernate不理解0（零）作为@Id列的值。我试图保存一个引用的对象，其@Id值为0.所以我将id值更改为1并且它工作= S
