这篇博客介绍了如何在Spring框架下实现单选按钮和复选框的功能。对于单选按钮，通过在student类中声明favoriteLanguage属性，并在student-form.jsp设置radiobutton属性，然后在student-confirmation.jsp页面回显选择。复选框的实现虽未详述，但可以推测类似的处理方式。

单选按钮：

在这里插入图片描述

首先在student类里面声明favoriteLanguage属性并且生成setter and getter方法，在student-form里面设置radiobutton属性，最后在student-confirmation页面调用student类的favoriteLanguage可以回显在页面上。

	private String favoriteLanguage;
		public String getFavoriteLanguage() {
		return favoriteLanguage;
	}
		public void setFavoriteLanguage(String favoriteLanguage) {
		this.favoriteLanguage = favoriteLanguage;
	}

		</form:select>
		
		<br><br>
		
		Favorite Language:
		
		Java <form:radiobutton path="favoriteLanguage" value="Java" />
		C# <form:radiobutton path="favoriteLanguage" value="C#" />
		PHP <form:radiobutton path="favoriteLanguage" value="PHP"/>
		Ruby <form:radiobutton path="favoriteLanguage" value="Ruby"/>
		<br><br>
		
		<input type = "submit" value="Submit" />
	
	</form:form>

<br> <br>

	Favorite Language: ${student.favoriteLanguage}

复选框

student类

	private String[] operatingSystems;
	 
	public String[] getOperatingSystems() {
		return operatingSystems;
	}

	public void setOperatingSystems(String[] operatingSystems) {
		this.operatingSystems = operatingSystems;
	}

student-form.jsp

		Operating System:
			Linux <form:checkbox path="operatingSystems" value="Linux" />
			Mac OS <form:checkbox path="operatingSystems" value="Mac OS" />
			MS Windows <form:checkbox path="operatingSystems" value="MS Windows " />
		<br><br>

student-confirmation.jsp

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

...	
<br> <br>
	Operating Systems:
<ul>
	<c:forEach var="temp" items="${student.operatingSystems }">
	
		<li>${temp}</li>
	</c:forEach>
</ul>
