springmvc映射对象

提交的标签的name属性要和java中model属性这两个单词一模一样才行

@RequestMapping(value="/modelautobind", method = {RequestMethod.POST})
public String modelAutoBind(HttpServletRequest request, Model model, AccountModel accountModel){
    
    model.addAttribute("accountmodel", accountModel);
    return "modelautobindresult";
}
