本文介绍如何在JSP页面中通过链接传递参数到Struts框架，并在Action类中处理这些参数，最后将参数显示在另一个JSP页面上。

JSP请求页面（传参）

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%
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 'index.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>
	向结果传参数
	<ol>
		<li><a href="user/user?type=1">传参数</a></li>
	</ol>
  </body>
</html>

struts.xml的配置（接收jsp传来的参数）

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
<constant name="struts.i18n.encoding" value="UTF-8"></constant>
<constant name="struts.ognl.allowStaticMethodAccess" value="true"></constant>
    <package name="user" extends="struts-default" namespace="/user">
        <action name="user" class="com.lbx.action.UserAction">
        	<result type="redirect">/success.jsp?t=${type}</result>
        </action>
    </package>
    
</struts>

Action的处理为参数体统set和get方法

package com.lbx.action;


import com.opensymphony.xwork2.ActionSupport;

@SuppressWarnings("serial")
public class UserAction extends ActionSupport{
	private int type;
	
	public int getType() {
		return type;
	}
	public void setType(int type) {
		this.type = type;
	}
	@Override
	public String execute() throws Exception {
		System.out.println("UserAction.execute()");
		return SUCCESS;
	}
	
	
}

success.jsp页面（读出传过来的值）

<%@ 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 'success.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>
    User Success!
	from valuestack: <s:property value="t"/><br/>
	from actioncontext: <s:property value="#parameters.t"/>
	<s:debug></s:debug>
  </body>
</html>
