弹簧MVC多模型同一形式上的属性型控制器断续器

html java spring-mvc modelattribute

我有一个表格，有两个模型属性，一个是公民，另一个是惩罚。这两个对象由 jquery 选项卡分隔。我在使窗体上的项目正确显示时遇到问题，有些正在显示，有些则没有。我的意思是html元素。

我不确定当页面上有多个ModleAttributes时控制器的外观。下面是代码示例：

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">             
                    <div class="divGroup" id="divCharInfo"> 
                    <fieldset>  
                    <legend>Characteristics Info</legend>
                            <ol>    
                                <li><form:label for="photo" path="photo">Select Photo</form:label>
                                    <form:input path="photo" type="file" id="photo" title="Upload a photo"/><form:errors path="photo" id="errors"/></li>

                                <li>
                                    <label>Select Gender</label>
                                    <form:select path="genderId" id="genderId" title="Select Your Gender">
                                    <form:options items = "${gender.genderList}" itemValue="genderId" itemLabel="genderDesc" />
                                    </form:select>
                                    <form:errors path="genderId" class="errors"/>
                                </li>

                                    <form:input path="weight" id="weight" title="Enter Weight"/><form:errors path="weight" id="errors"/>
                                </li>

        </div>

    </body>
</html>

控制器

@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，但是当我运行它时，tab2中没有任何内容显示，也没有显示tab1中的所有元素。

如果你可以使用Spring表单绑定多个模型，我不这么认为。事实上，您应该看看弹簧装订形式。http://static.springsource.org/spring/docs/1.1.5/taglib/tag/BindTag.html请看一下示例代码。我还没有测试代码。如果出现任何问题，请告知。

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
}

控制器

@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.

        }
    }

我已经在这里的链接中给出了替代方法

<form:form method="POST" modelAttribute="applicationGeneralInformation">
  <div class="section2">
    <h2>General Informaion</h2>

    <form:input type="hidden" path="id" id="id"/>
    <label for="app_version">Version</label>: <form:input type="text" id="app_version" path="version"/><br/>
    <label for="app_func_desc">Description</label>: <form:input type="text" id="app_func_desc"
                                                                       path="functionalDescription"/><br/>
   <label for="app_sec_func">Functions</label>: <form:input type="text" id="app_sec_func"
                                                                  path="securityFunctions"/><br/>
