这可能是一个非常简单的错误。请帮忙。 我有两个<form:form>一个标签页针对home.jsp：Java - 两个不同的@ModelAttribute在同一个视图上占用相同的值
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>

<div>
<form:form name="SignUpForm" modelAttribute="signUpUser" action="signup" method="post">

<form:errors path="email" cssClass="error" />
<br/>

<form:errors path="password" />
<br/>
<input type="submit" id="id_signUp" value="Sign Up">

</div>

每个表单由不同的控制器处理。问题是，当我填写（只）的一种形式，并点击提交按钮，无论是ModelAttribute s的越来越具有相同值
居住没有什么特别的我的控制器：
@RequestMapping("/login")
public String login(@ModelAttribute("loginUser") User user,
BindingResult result, @ModelAttribute("signUpUser") User signUpUser,
BindingResult signUpResult, ModelMap model, HttpServletRequest request,
HttpServletResponse response) {
// Here, both user and signUpUser have the same value (WHY?)
// But I dint fill the sign up form at all
loginFormValidator.validate(user, result);
if(Errors in `result`)
return "forward:/home";
// Authentication Logic
request.getSession().setAttribute("s_user_obj", some_variable);
return "forward:/home";
}
更新：
下面是生成的HTML。 前login行动：
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">

<body>
<div>
<form id="loginUser" name="loginForm" action="login" method="post">
<br/>
Email: <input id="loginEmail" name="email" name="loginEmail" type="text" value=""/>
<br/>
password: <input id="password" name="password" name="loginPassword" Id="loginPassword" type="password" value=""/>
<br/>
<input type="submit" id="id_login" value="Login">

<div>
<form id="signUpUser" name="SignUpForm" action="signup" method="post">

<br/>

它看起来像一个错误，但我希望看得更远。你可以发布这个JSP生成的HTML吗？ –
@subirkumarsao我已经用HTML更新了这个问题。在此先感谢 – th3an0maly
