本文介绍了一个基于Struts框架的示例应用，通过DisAction类实现了地址添加与更新的功能。具体展示了如何使用JSP页面配合Struts标签库进行表单操作，并详细解释了配置文件中对DisAction类的映射。

dis.jsp

<%@ page language="java" pageEncoding="utf-8"%>
<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean"%>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html"%>

<html>
	<head>
		<title>JSP for DisForm form</title>
	</head>
	<body>
		<html:form action="/dis.do">
			address  add: <html:text property="address" />
			
			<input type="hidden" name="status" value="add">
			<br>

			<html:submit />
			<html:cancel />
		</html:form>
		<html:form action="/dis.do">
			address  add: <html:text property="address" />
			
			<input type="hidden" name="status" value="update">
			<br>

			<html:submit />
			<html:cancel />
		</html:form>
		
	</body>

配置文件

<action-mappings>
<action attribute="disForm" input="/dis.jsp" name="disForm"
