Spring MVC多个ModelAttribute在同一个表单上 [英] Spring MVC Multiple ModelAttribute On the Same Form
本文介绍了Spring MVC多个ModelAttribute在同一个表单上的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有两个ModelAttributes的表单，一个是公民，另一个是惩罚。这两个对象由jquery选项卡分隔。我在获取表单上的项目时出现问题，显示正确，有些正在显示，有些则没有。我的意思是html元素。
我不确定Controller在页面上有多个ModleAttributes时的外观。 Under是代码示例：
Page
< title>公民注册< / title>
< / head>
< body>
< div id =tabs>
< ul>
< li>< a href =＃tab1>公民注册< / a>< / li>
< li>< a href =＃tab2>惩罚< / a>< / li>
< / ul>
< div id =tab1>
< form：form id =citizenRegistrationname =citizenRegistrationmethod =postmodelAttribute =citizensaction =citizen_registration.htm>
< div id =divRightclass =mainDiv>
< div class =divGroupid =divCharInfo>
< fieldset>
< legend>特征信息< / legend>
< ol>
< li>< form：label for =photopath =photo>选择照片< / form：label>
< li>
< label>选择性别< / label>
< / form：select>
< form：errors path =genderIdclass =errors/>
< / li>
$ b $ lt; li>< form：label for =weightpath =weight> Enter Weight< i>（lbs）< / i>< / form：label>
< form：input path =weightid =weighttitle =Enter Weight/>< form：errors path =weightid =errors/>
< / li>
< li>< form：label for =heightpath =height> Enter Height< i>（feet）< / i>< / form：label>
< form：input path =heightid =heighttitle =Enter Height/>< form：errors path =heightid =errors/>
< / li>
.......................
< div id =tab2>
< form：form id =punishmentRegistrationname =punishmentRegistrationmethod =postmodelAttribute =punishmentaction =punishment_registration.htm>
< li>
< form：label for =punishmentIdpath =punishmentId>处罚编号< / form：label>
< form：input path =punishmentIdid =punishmentId/>< form：errors path =punishmentIdid =errors/>
< / li>
< li>
< form：label for =crimeRecNopath =crimeRecNo>选择犯罪< / form：label>
< form：errors path =crimeRecNoid =errors/>
< / li>
< li>
< form：label for =monitoringStDatepath =monitoringStDate>开始日期< / form：label>
< form：input path =monitoringStDateid =monitoringStDate/>< form：errors path =monitoringStDateid =errors/>
< / li>
< li>
< form：label for =monitoringEnDatepath =monitoringEnDate>结束日期< / form：label>
< form：input path =monitoringEnDateid =monitoringEnDate/>< form：errors path =monitoringEnDateid =errors/>
< / li>
< / ol>
< / form：form>
< / div>
< / div>
< / body>
< / html>
控制器
@RequestMapping（value =citizen_registration.htm，method = RequestMethod.GET）
public ModelAndView loadPage（HttpServletRequest请求，
HttpServletResponse响应，
@ModelAttribute公民公民，@ModelAttribute处罚惩罚，
BindingResult结果，
ModelMap m，模型模型）抛出异常{
//这里的代码
返回新的ModelAndView（citizen_registration）;
这是我的代码，但是当我运行它时，tab2中的任何内容都不显示，并且不显示tab1中的所有元素。
解决方案
我不这么认为，如果您可以使用Spring表单绑定多个模型。事实上，你应该看看春季装订表格。
http://static.springsource.org /spring/docs/1.1.5/taglib/tag/BindTag.html
查看示例代码。我没有测试过这些代码。让我们知道有任何问题。
模型
public class用户{
私人字符串用户名;
私人字符串密码;
..设置者和获取者
}
public class UserProfile {
private String firstName;
private String lastName;
setter and getter
}
控制器
$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $' ModelMap map）{
User user = new User（）; //会推荐使用spring容器来创建对象
UserProfile profile = new UserProfile（）;
map.addAttribute（'user'，user）;
map.addAttribute（'profile'，profile）;
returnform
}
@RequestMapping（....）
public String newAccountForm（@ModelAttrbite（'User'）用户用户，BindingResult resultUser，@ModelAttribute（'UserProfile'）UserProfile userProfile，BindingResult resultProfile）{
//检查每个模型的绑定结果。如果无效，请再次返回表单页面
//根据需要进一步处理。

I have a form with two ModelAttributes one is citizens and the other is punishment. The two objects are separated by jquery tabs. I am having problems in getting the items on the form to display properly some are being displayed and some are not. I mean the html elements.
I am not sure how the Controller would look when there is multiple ModleAttributes on the page. Under is a sample of the code:
Page
<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 = "${gender.genderList}" itemValue="genderId" itemLabel="genderDesc" />
</form:select>
<form:errors path="genderId" class="errors"/>
</li>
<li><form:label for="weight" path="weight">Enter Weight <i>(lbs)</i></form:label>
<form:input path="weight" id="weight" title="Enter Weight"/><form:errors path="weight" id="errors"/>
</li>
<li><form:label for="height" path="height">Enter Height <i>(feet)</i></form:label>
<form:input path="height" id="height" title="Enter Height"/><form:errors path="height" id="errors"/>
</li>
.......................
<div id="tab2">
<form:form id="punishmentRegistration" name ="punishmentRegistration" method="post" modelAttribute="punishment" action="punishment_registration.htm">
<ol>
<li>
<form:label for ="punishmentId" path="punishmentId">Punishment Number</form:label>
<form:input path="punishmentId" id="punishmentId"/><form:errors path="punishmentId" id="errors"/>
</li>
<li>
<form:label for="crimeRecNo" path="crimeRecNo">Select Crime</form:label>
<form:select path="crimeRecNo" id="CrimeRecNo" title="Select Crime">
<form:options items = "${crime.crimeList}" itemValue="crimeRecNo" itemLabel="crimeRecNo" title="crimeDesc"/>
</form:select>
<form:errors path="crimeRecNo" id="errors"/>
</li>
<li>
<form:label for ="monitoringStDate" path="monitoringStDate"> Start Date </form:label>
<form:input path="monitoringStDate" id="monitoringStDate"/><form:errors path="monitoringStDate" id="errors"/>
</li>
<li>
<form:label for ="monitoringEnDate" path="monitoringEnDate"> End Date </form:label>
<form:input path="monitoringEnDate" id="monitoringEnDate"/><form:errors path="monitoringEnDate" id="errors"/>
</li>
</ol>
</form:form>
</div>
</div>
</body>
</html>
Controller
@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");
This is my code however when i run it nothing in tab2 is displayed andnot all elements in tab1 is shown.
解决方案
I don't think so if you can bind multiple models using the Spring form. In fact you should take a look in the spring binding form. http://static.springsource.org/spring/docs/1.1.5/taglib/tag/BindTag.html Take a look in the sample code. I have not tested the code. Let know in case of any issues.
Model
public class User{
private String username;
private String password;
..Setter and Getters
}
public class UserProfile{
private String firstName;
private String lastName;
setter and getter
}
Controller
@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>
