例子:

SpringMVC 的表单标签库

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/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=UTF-8">
<title>Insert title here</title>
</head>
<body>
<form:form modelAttribute="user" action="register" method="post">
<table>
	<tr>
		<td>名字:</td>
		<td><form:input path="name"/></td>
	</tr>
	<tr>
		<td>性別:</td>
		<td><form:input path="sex"/></td>
	</tr>
	<tr>

	</tr>

</table>
</form:form>

然后在controller包中的方法中加入:

model.addAttribute("user",user);

一个小栗子:

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://xmlns.jcp.org/xml/ns/javaee"
	xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
	id="WebApp_ID" version="3.1">
	<!-- The front controller of this Spring Web application, responsible for handling all application requests -->
	<servlet>
		<servlet-name>springDispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springmvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<!-- Map all requests to the DispatcherServlet for handling -->
	<servlet-mapping>
		<servlet-name>springDispatcherServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	

</web-app>

放在src目录下的springmvc.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
		http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd">
	<context:component-scan base-package="com.majun"></context:component-scan>

	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	<property name="prefix" value="/WEB-INF/views/"/>
	<property name="suffix" value=".jsp"></property>

	</bean>
</beans>
放在src目录下的不同包下两个实体类:
package com.majun.controller;//控制层的包
import java.util.ArrayList;
import java.util.LinkedList;
import java.util.List;

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.majun.entity.*;
@Controller
@RequestMapping("spring")
public class Test {
	@RequestMapping(value="/testRadiobuttons",method=RequestMethod.GET)
	public String testRadiobuttons(Model model) {
		User user=new User();
		user.setSex("男");
		List<String> sexList=new ArrayList<String>();
		sexList.add("男");
		sexList.add("女");
		model.addAttribute("user",user);
		model.addAttribute("sexList",sexList);	
		return "testRadiobuttons";
	}
	
}
package com.majun.entity;//实体类

public class User {
	private String sex;

	public String getSex() {
		return sex;
	}

	public void setSex(String sex) {
		this.sex = sex;
	}
	
}

放在WEB-INF目录下的views文件夹下(视图层):

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
    <%@ taglib prefix="form" uri="http://www.springframework.org/tags/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=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h2>hello</h2>
<form:form modelAttribute="user" method="post" action="testRadiobuttons">
<table>
	<tr>
		<td>性别:</td>
		<td><form:radiobuttons path="sex" items="${sexList }"/>
		</td>
	</tr>
</table>
</form:form>
</body>
</html>
