Spring MVC：控制器函数未在表单提交时调用

时间：2016-09-30 21:13:39

标签： spring jsp spring-mvc controller

我是使用Spring MVC框架的新手，并设计了一个有两种形式的html页面。一个是登录（表单id：loginform），另一个是注册（（表单id：signupform）。正在为登录页面正确调用控制器，但是对于注册，没有任何反应（没有控制器被调用），页面只是刷新我无法找到问题的根源。这是我的JSP页面：

Login.jsp

你的单身表单有http方法POST，但你的控制器是http方法GET

您的JSP：

<form:form id="signupform" class="form-horizontal" role="form"
                        method="POST" modelAttribute="userForm"
                        action="<c:url value='/adduser' />">

你的控制器：

@RequestMapping(value = "/adduser", method = RequestMethod.GET)
    public ModelAndView createUser(@ModelAttribute("userForm") User user,
            BindingResult result) {
