我有两个ModelAttributes形式之一是公民，另一种是惩罚。两个目的通过jquery的制表符分隔。我有问题获得表上的项目，以正确显示一些被显示，有些则不是。我指的是html元素。

我不知道如何当在页面上的多个ModleAttributes控制器看起来。下是代码的示例：

页

<title>Citizen Registration</title>

    </head>

    <body>  
        <div id="tabs"> 

        <ul>
            <li><a href="#tab1">Citizen Registration</a></li>
            <li><a href="#tab2">Punishment</a></li>
        </ul>


        <div id="tab1">
            <form:form id="citizenRegistration" name ="citizenRegistration" method="post" modelAttribute="citizens" action="citizen_registration.htm">
                <div id="divRight" class="mainDiv">

调节器

@RequestMapping(value="citizen_registration.htm", method = RequestMethod.GET)
    public ModelAndView loadPage(HttpServletRequest request,
                                 HttpServletResponse response,
                                 @ModelAttribute Citizens citizens, @ModelAttribute Punishment punishment,
                                 BindingResult result,
                                 ModelMap m, Model model) throws Exception {

//code here

return new ModelAndView("citizen_registration");

这是我的代码然而，当我在TAB2运行它没有显示在ANDNOT TAB1所有元素所示。

Answer 1:

我不这么认为，如果能结合使用Spring形式的多个模型。事实上，你应该在春季结合形式的样子。 http://static.springsource.org/spring/docs/1.1.5/taglib/tag/BindTag.html以示例代码看看。我没有测试的代码。我们知道在任何问题时。

模型

public class User{

private String username;
private String password;

..Setter and Getters
}

public class UserProfile{
private String firstName;
private String lastName;

setter and getter
}

调节器

@Controller
public class MyController{
    @RequestMapping(....)
    public String newAccountForm(ModelMap map){
        User user = new User(); //Would recommend using spring container to create objects
        UserProfile profile = new UserProfile();

        map.addAttribute('user', user);
        map.addAttribute('profile', profile);

        return "form"
    }




     @RequestMapping(....)
        public String newAccountForm(@ModelAttrbite('User')User user, BindingResult resultUser, @ModelAttribute('UserProfile')UserProfile userProfile, BindingResult resultProfile){

//Check the binding result for each model. If not valid return the form page again
//Further processing as required.

        }
    }

JSP

<%@taglib  uri="http://www.springframework.org/tags" prefix="spring">

<form action="" method="post">

<spring:bind path="user.username">
   <input type="text" name="${status.expression}" value="${status.value}"><br />
        </spring:bind>

<spring:bind path="user.password">
   <input type="password" name="${status.expression}" value="${status.value}"><br />
        </spring:bind>

<spring:bind path="profile.firstName">
   <input type="text" name="${status.expression}" value="${status.value}"><br />
        </spring:bind>
<spring:bind path="profile.lastName">
   <input type="text" name="${status.expression}" value="${status.value}"><br />
        </spring:bind>

<input type="submit" value="Create"/>
</form>
