Hibernate查询超时异常-我无法将数据保存到数据库

Question

I would like to save an article, but i got an exception. I don't know what do I do wrong. I have three entities: User.class, Category.class and Article.class.

User has these atributes:

• id
• name
• email
• password
• List of articles (One-To-Many)

Category has these atributes:

• id
• name
• List of categories (Many-To-Many)

Article has these attributes:

• id
• title
• content
• publishDate
• User (Many-To-One)
• List of categories (Many-To-Many)

There are my controller and JSP file.

ArticleController.class

@Controller
public class ArticleController {
@Autowired
ArticleService articleService;
@Autowired
CategoryService categoryService;
@Autowired
UserService userService;

@ModelAttribute("article")
public Article construct(){
    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));
}

@InitBinder
protected void initBinder(HttpServletRequest request,
        ServletRequestDataBinder binder) throws Exception {
    binder.registerCustomEditor(Integer.class, new CustomNumberEditor(
            Integer.class, true));
}}

article.jsp

<form:form commandName="article" cssClass="form-horizontal">

            </c:forEach>
        </form:select>
    </div>
</div>

<div class="form-group">
    <div class="col-sm-2">
        <input type="submit" value="Uložit" class="btn btn-lg btn-primary">
    </div>
</div>

Answer 1

It looks to me like you are using Hibernate 3.x. If this is the case, I would make sure you are on version 3.6.10+ of Hibernate core. Older versions may not have the necessary class definition that the spring framework is looking for. The following link shows Hibernate 3.6.10 has the class definition you are missing: http://tool.oschina.net/uploads/apidocs/hibernate-3.6.10/org/hibernate/QueryTimeoutException.html

Answer 2

I've got the same error when saving de object. Well It's weird but apparently hibernate doesn't understand 0 (zero) as a value for @Id columns. I was trying to save a referenced object and its @Id value was 0. So I changed the id value to 1 and it worked =S
