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"%>








 

    userName:

    email:  

    password:

    Gender:male
           female

           
           
    hobby:one
           two
          three
         

    remarks:
    
    
    
 



<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>








java265.com--ShowUserInfo 


userName: ${requestScope.u.userName}
 

email:    ${requestScope.u.eMail} 




passWord:    ${requestScope.u.passWord} 




hobby:    ${requestScope.u.hobby} 


Gender:    ${requestScope.u.gender} 


remarks:    ${requestScope.u.remarks} 

运行效果如下图所示:
