原始碼JS
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%> 
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>My JSP `Struts_token.jsp` starting page</title>
    
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->

  </head>
  
  <body>
         <!-- 防止表單重複提交，記得在form表單裡填上<s:token></s:token>      -->
      <!-- action="token"、action="tokenSession" -->
      <s:form action="token.action" namespace="/test" method="post">
          姓名:<s:textfield name="name"/><s:token></s:token>
          <input type="submit" value="傳送"/>
      </s:form>
  </body>
</html>



其實很簡單實用，只要在表單中在form表單裡填上<s:token></s:token>   就可以了，是不是很簡單。原理就是它會自動生成一串二進位制碼。STRUTS會自動在提交的時候去做比對。
