我试图使用弹簧形式控制器绑定输入类型复选框,但我失败了.
这里我发布了Controller,bean和jsp的例子,还有一件事是我无法使用.
以下是代码:
控制器:
package com.test.web;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import com.vaannila.domain.User;
import com.vaannila.service.UserService;
@SuppressWarnings("deprecation")
public class UserController extends SimpleFormController {
private UserService userService;
public UserController() {
setCommandClass(User.class);
setCommandName("user");
}
public void setUserService(UserService userService) {
this.userService = userService;
}
@Override
protected ModelAndView onSubmit(Object command) throws Exception {
User user = (User) command;
user.setCommunity(user.getCommunity());
userService.add(user);
return new ModelAndView("userForm","user",user);
}
}
JSP:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Registration Page</title>
<script>
function submitForm(){
document.testForm.submit();
}
</script>
</head>
<body>
<form:form method="POST" commandName="user" name="testForm" action="./userRegistration.htm">
<table>
<tr>
<td>User Name :</td>
<td><form:input path="name" /></td>
</tr>
<tr>
<td>Password :</td>
<td><form:password path="password" /></td>
</tr>
<tr>
<td>Gender :</td>
<td><form:radiobutton path="gender" value="M" label="M" />
<form:radiobutton path="gender" value="F" label="F" /></td>
</tr>
<tr>
<td>Country :</td>
<td><form:select path="country">
<form:option value="0" label="Select" />
<form:option value="1" label="India" />
<form:option value="2" label="USA" />
<form:option value="3" label="UK" />
</form:select></td>
</tr>
<tr>
<td>About you :</td>
<td><form:textarea path="aboutYou" /></td>
</tr>
<tr>
<td>Community :</td>
<td><input type="checkbox" name="community" value="Hibernate"/>Hibernate</br>
<input type="checkbox" name="community" value="test"/>test</br>
<input type="checkbox" name="community" value="test1"/>test1</br>
</td>
</tr>
<tr>
<td></td>
<td><form:checkbox path="mailingList"
label="Would you like to join our mailinglist?" /></td>
</tr>
<tr>
<td colspan="2"><input type="submit" onclick="submitForm();"></td>
</tr>
</table>
</form:form>
</body>
</html>
Java bean:
package com.test.domain;
public class User {
private String name;
private String password;
private String gender;
private String country;
private String aboutYou;
private String[] community;
private Boolean mailingList;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public String getCountry() {
return country;
}
public void setCountry(String country) {
this.country = country;
}
public String getAboutYou() {
return aboutYou;
}
public void setAboutYou(String aboutYou) {
this.aboutYou = aboutYou;
}
public String[] getCommunity() {
return community;
}
public void setCommunity(String[] community) {
this.community = community;
}
public Boolean getMailingList() {
return mailingList;
}
public void setMailingList(Boolean mailingList) {
this.mailingList = mailingList;
}
}
我尝试了不同的方法,但没有运气.请提示任何提示.
如果未选中该复选框,浏览器将不会在请求中发送该字段.该值将为"true"或未发送.你将永远不会得到"虚假"的价值.
为每个复选框添加带_name的隐藏字段
EX:
<input type="checkbox" name="community" value="Hibernate"/>
<input type="hidden" name="_community" value="on"/>
然后,春天将照顾它.
