spring2.5既不是BindingResult，也不是bean name的普通目标对象；xxx“；可用作请求属性

请帮帮我。。。我正在使用Spring2.5 我收到一条错误消息。这个

javax.servlet.ServletException:javax.servlet.jsp.jsptageException:bean名称“user”的BindingResult和普通目标对象都不能作为请求属性使用 此处URL//localhost:8080/Projectname/Main\u login.jsp

p/w：

看起来您提交的表单试图将用户对象绑定到请求。。您的请求方法签名需要如下所示：

public String onSubmit(@ModelAttribute("user") User user, BindingResult binding, HttpSession session) {

我认为您还需要在显示表单的初始get调用上设置请求中的User对象

例如

你能粘贴你的代码控制器、jsp和XMLBean声明吗Spring 2.5很旧/有缺陷。坚持升级到更新/更高版本。我粘贴我的代码。我认为是这样。但是我必须使用Spring2.5来保存完整的堆栈跟踪和您请求的URL的结构。非常感谢。另外，我用的是玻璃鱼。在我的项目中，有sun_web.xml。可以吗？我想这可能是我的错。。。这让我发疯。。我看了“Spring工作正常。但是UserBean是由JSF实例化的。因此Spring没有注意到Bean将被创建，并且无法注入服务。”在另一页。我没有使用Glassfish服务器，您可以在这里查看关于不同web xml文件的一些信息。我打赌你不需要sun_web.xml文件，事实上你应该将web.xml文件配置为指向Spring MVC dispatcher，这样你就可以使用Spring映射请求了。谢谢colws！我成功了。问题是我的项目的上下文根和目录结构。无论如何，谢谢！！！

public String onSubmit(@ModelAttribute("user") User user, BindingResult binding, HttpSession session) {

model.addAttribute("user", new User());
