我看了几乎所有的答案，但我找不到我的代码中的问题是什么。你能帮我一个忙吗?

}提前感谢!
在您的模型中为JSP的URL添加新方法
@Override
protected ModelAndView processStart(HttpServletRequest request, HttpServletResponse response, BindException be) throws Exception {
User user=new User();
return new ModelAndView("UserJSPname","userForm",user);
}
它基本上初始化空User对象和设置为model。
