。
以下示例显示如何使用Spring Web MVC框架在表单中使用多个复选框。首先,让我们使用Eclipse IDE,并按照以下步骤使用Spring Web Framework开发基于动态窗体的Web应用程序:
步骤描述
创建一个名为HelloWeb的项目,在一个包com.tutorialspoint下,如Spring MVC - Hello World Example章节所述。
在com.tutorialspoint包下创建一个Java类User,UserController。
在jsp子文件夹下创建一个视图文件user.jsp,users.jsp。
最后一步是创建所有源和配置文件的内容并导出应用程序,如下所述。
User.java
package com.tutorialspoint;
public class User {
private String username;
private String password;
private String address;
private boolean receivePaper;
private String [] favoriteFrameworks;
public String getUsername() {
return username;
public void setUsername(String username) {
this.username = username;
public String getPassword() {
return password;
public void setPassword(String password) {
this.password = password;
public String getAddress() {
return address;
public void setAddress(String address) {
this.address = address;
public boolean isReceivePaper() {
return receivePaper;
public void setReceivePaper(boolean receivePaper) {
this.receivePaper = receivePaper;
public String[] getFavoriteFrameworks() {
return favoriteFrameworks;
public void setFavoriteFrameworks(String[] favoriteFrameworks) {
this.favoriteFrameworks = favoriteFrameworks;
UserController.java
package com.tutorialspoint;
import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.ui.ModelMap;
@Controller
public class UserController {
@RequestMapping(value = "/user", method = RequestMethod.GET)
public ModelAndView user() {
User user = new User();
user.setFavoriteFrameworks((new String []{"Spring MVC","Struts 2"}));
ModelAndView modelAndView = new ModelAndView("user", "command", user);
return modelAndView;
@RequestMapping(value = "/addUser", method = RequestMethod.POST)
public String addUser(@ModelAttribute("SpringWeb")User user,
ModelMap model) {
model.addAttribute("username", user.getUsername());
model.addAttribute("password", user.getPassword());
model.addAttribute("address", user.getAddress());
model.addAttribute("receivePaper", user.isReceivePaper());
model.addAttribute("favoriteFrameworks", user.getFavoriteFrameworks());
return "users";
@ModelAttribute("webFrameworkList")
public List<String> getWebFrameworkList()
List<String> webFrameworkList = new ArrayList<String>();
webFrameworkList.add("Spring MVC");
webFrameworkList.add("Struts 1");
webFrameworkList.add("Struts 2");
webFrameworkList.add("Apache Wicket");
return webFrameworkList;
这里第一个服务方法user(),我们已经通过名为“command”的ModelAndView对象中传递了一个空的User对象,因为如果您在JSP中使用<form:form>标签,Spring框架将期望一个名为“command”的对象文件。所以当user()方法被调用时,它返回user.jsp视图。
将在HelloWeb/addUser URL上针对POST方法调用第二个服务方法addUser()。您将根据提交的信息准备您的模型对象。最后,将从服务方法返回“user”视图,这将导致渲染users.jsp
user.jsp
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<title>Spring MVC Form Handling</title>
</head>
<h2>User Information</h2>
<form:form method="POST" action="/HelloWeb/addUser">
<table>
<td><form:label path="username">User Name</form:label></td>
<td><form:input path="username" /></td>
<td><form:label path="password">Age</form:label></td>
<td><form:password path="password" /></td>
<td><form:label path="address">Address</form:label></td>
<td><form:textarea path="address" rows="5" cols="30" /></td>
<td><form:label path="receivePaper">Subscribe Newsletter</form:label></td>
<td><form:checkbox path="receivePaper" /></td>
<td><form:label path="favoriteFrameworks">Favorite Web Frameworks</form:label></td>
<td><form:checkboxes items="${webFrameworkList}" path="favoriteFrameworks" /></td>
<td colspan="2">
<input type="submit" value="Submit"/>
</table>
</form:form>
</body>
</html>
这里我们使用<form:checkboxes />标签来呈现HTML复选框。例如
<form:checkboxes items="${webFrameworkList}" path="favoriteFrameworks" />
它将呈现以下HTML内容。
<input id="favoriteFrameworks1" name="favoriteFrameworks" type="checkbox" value="Spring MVC" checked="checked"/>
<label for="favoriteFrameworks1">Spring MVC</label>
</span>
<input id="favoriteFrameworks2" name="favoriteFrameworks" type="checkbox" value="Struts 1"/>
<label for="favoriteFrameworks2">Struts 1</label>
</span>
<input id="favoriteFrameworks3" name="favoriteFrameworks" type="checkbox" value="Struts 2" checked="checked"/>
<label for="favoriteFrameworks3">Struts 2</label>
</span>
<input id="favoriteFrameworks4" name="favoriteFrameworks" type="checkbox" value="Apache Wicket"/>
<label for="favoriteFrameworks4">Apache Wicket</label>
</span>
<input type="hidden" name="_favoriteFrameworks" value="on"/>
users.jsp
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<title>Spring MVC Form Handling</title>
</head>
<h2>Submitted User Information</h2>
<table>
<td>Username</td>
<td>${username}</td>
<td>Password</td>
<td>${password}</td>
<td>Address</td>
<td>${address}</td>
<td>Subscribed to Newsletter</td>
<td>${receivePaper}</td>
<td>Favorite Web Frameworks</td>
<td> <% String[] favoriteFrameworks = (String[])request.getAttribute("favoriteFrameworks");
for(String framework: favoriteFrameworks) {
out.println(framework);
%></td>
</table>
</body>
</html>
完成创建源和配置文件后,导出应用程序。右键单击应用程序并使用Export->WAR File选项,并将您的HelloWeb.war文件保存在Tomcat的webapps文件夹中。
现在启动您的Tomcat服务器,并确保您可以使用标准浏览器从webapps文件夹访问其他网页。现在尝试URL http://localhost:8080/HelloWeb/user,如果您的Spring Web应用程序的一切都很好,您应该会看到以下结果:
提交所需信息后,点击提交按钮提交表单。如果您的Spring Web应用程序的一切都很好,您应该会看到以下结果:
