这篇博客详细介绍了如何在Struts框架中实现表格的数据输出，并探讨了结合validation.xml进行用户输入验证的方法，通过实例代码展示了从index.jsp页面到ZhuceAction.java控制器的流程，最后展示验证结果在welcome.jsp上的呈现。

index.jsp:

<%@ page contentType="text/html; charset=gb2312" language="java" errorPage="" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312"/>
<title>请输入您的注册信息</title>
</head>
<body>
<H1>请输入您的注册信息</H1>
<s:form action="r" >
	<s:textfield name="name" label="用户名"></s:textfield>
  	<s:password name="pass" label="密码"></s:password>
  	<s:textfield name="age" label="年龄"></s:textfield>
  	<s:textfield name="birth" label="生日"></s:textfield>
	<s:submit value="注册" />
</s:form>
</body>
</html>

ZhuceAction.java:
