SpringMVC如何获取单选框的值呢？
单选框是web开发中常用的一种html控件，那么SpringMVC中如何获取其传送至后台的值呢？下文将一一道来，如下所示:
实现思路:
1.创建一个动态web工程
2.建立一个实体用于存储数据，建立相应的Controller方法
3.建立两个jsp页面，一个用于提交表单，一个用于展示数据，如下所示： user.java

package com.java265.helloworld.Entity;
public class User {
private String userName;
private String eMail;
private String passWord;
private String remarks;
private String hobby; // 爱好
private String gender;// 性别
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public String getHobby() {
return hobby;
}
public void setHobby(String hobby) {
this.hobby = hobby;
}
public User(String userName, String eMail, String passWord, String remarks, String hobby) {
super();
this.userName = userName;
this.eMail = eMail;
this.passWord = passWord;
this.remarks = remarks;
this.hobby = hobby;
}
public User(String userName, String eMail, String passWord, String remarks, String hobby, String gender) {
super();
this.userName = userName;
this.eMail = eMail;
this.passWord = passWord;
this.remarks = remarks;
this.hobby = hobby;
this.gender = gender;
}
public String getRemarks() {
return remarks;
}
public void setRemarks(String remarks) {
this.remarks = remarks;
}
public User(String userName, String eMail, String passWord, String remarks) {
super();
this.userName = userName;
this.eMail = eMail;
this.passWord = passWord;
this.remarks = remarks;
}
public User() {
super();
}
public User(String userName, String eMail) {
super();
this.userName = userName;
this.eMail = eMail;
}
public User(String userName, String eMail, String passWord) {
super();
this.userName = userName;
this.eMail = eMail;
this.passWord = passWord;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String geteMail() {
return eMail;
}
public void seteMail(String eMail) {
this.eMail = eMail;
}
public String getPassWord() {
return passWord;
}
public void setPassWord(String passWord) {
this.passWord = passWord;
}
}
建立Controller Post方法用于接收参数值
package com.java265.helloworld.Controller;
import javax.servlet.http.HttpServletRequest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.java265.helloworld.Entity.User;
@Controller
public class UserController {
@Autowired
private HttpServletRequest request;
/**
* 用户返回用户注册
*
*/
@RequestMapping(value = "/userReg", method = RequestMethod.GET)
public String userReg() {
return "userReg";
}
/**
*
* 使用Spring MVC获取文本变量
*
* @param userName :此出的名字缺省情况下只需同表单中的name对应即可获取数值
* @param emailAddress: 同上
*
* @return
*/
@RequestMapping(value = "/userReg", method = RequestMethod.POST)
public String userReg(String userName, String emailAddress, String passWord, String txtRemarks, String chkHobby,
String gender, Model model) {
User u = new User(userName, emailAddress, passWord, txtRemarks, chkHobby, gender);
model.addAttribute("u", u);
return "showUserInfo";
}
}
建立注册页面及数据展示页面
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<form action="/com.java265.helloworld/userReg" method="post">
userName:<input type="text" name="userName" /><br />
email: <input type="text" name="emailAddress" /><br />
password:<input type="password" name="passWord" /><br />
Gender:<input type="radio" name="gender" id ="gender1" value="-1" ><label for="gender1" >male</label>
<input type="radio" name="gender" id ="gender2" value="-1" ><label for="gender2" >female</label><br />
hobby:<input type="checkBox" id="hobby1" name="chkHobby" value="1" /><label for="hobby1" >one</label>
<input type="checkBox" id="hobby2" name="chkHobby" value="2" /> <label for="hobby2" >two</label>
<input type="checkBox" id="hobby3"name="chkHobby" value="3" /><label for="hobby3" >three</label>
<br/>
remarks:<textarea rows="3" cols="6" name="txtRemarks"></textarea>
<input type="submit" value="submit" />
</form>
</body>
</html>
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
java265.com--ShowUserInfo <br />
<hr />
userName: ${requestScope.u.userName}
<br />
email: ${requestScope.u.eMail} <br />
<br />
passWord: ${requestScope.u.passWord} <br />
<br />
hobby: ${requestScope.u.hobby}
<br />
Gender: ${requestScope.u.gender}
<br />
remarks: ${requestScope.u.remarks}
<br />
</body>
</html>
运行效果如下图所示:
