java - eclipse Spring MVC 4 +Hibernate 和 MySQL + Tiles.xml 中的 HTTP 状态 404

Question

我已经搜索了我的错误，但一无所获。我的代码中仍然存在错误，所以我必须在这里发布我的问题。当我在 eclipse 中使用 tomcat 服务器运行我的项目时，出现错误。我已经在 Spring MVC 4 + Hibernate 和 MongoDB 中完成了该项目。现在我必须使用 MySQL 切换到 Hibernate，我正在 eclipse 中启动该项目。但是当我用 hibernate 完成 spring 的配置时，它显示错误。错误和项目结构如下: enter image description here

提前谢谢您。

尝试http://localhost:8080/DMS_MySQL/login 。另请尝试将您的登录 Controller 更改为:

@RequestMapping(value = {"/login", "/"}, method = RequestMethod.GET)
public String execute(HttpSession session, Model model) throws Exception {
    model.addAttribute("user", new UserBean());
    UserBean tempUser = (UserBean) session.getAttribute("USER");        
    if (tempUser != null) {
        return "redirect:/home";
    }
    return "login";//typo in your code
}

我假设您已经在图 block 配置中定义了登录映射。
