dev*_*dar 22 html java spring-mvc modelattribute
我有一个有两个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.我在获取正确显示表单上的项目时遇到问题,有些正在显示,有些则没有.我指的是html元素.
当页面上有多个ModleAttributes时,我不确定Controller的外观.下面是代码的示例:
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">
<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>

@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,显示tab2中没有任何内容,并且不显示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.实际上你应该看看弹簧绑定形式. http://static.springsource.org/spring/docs/1.1.5/taglib/tag/BindTag.html 查看示例代码.我没有测试过代码.如有任何问题,请告知.
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
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.
}
}
<%@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">

</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>
