package cn.itcast.b_action;public class HelloWorldAction {private String savepath;public String getSavepath() {return savepath;}public void setSavepath(String savepath) {this.savepath = savepath;}public String execute() {return "success";}}

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN""http://struts.apache.org/dtds/struts-2.3.dtd"><struts><package name="" namespace="/test" extends="struts-default"><action name="message" class="cn.itcast.b_action.HelloWorldAction"method="execute"><!-- 当这个数据要经常变化时使用Action注入 例：公司名称,只要在这里改就ok了,谁使用这个软件谁就来这里改--><param name="savepath">中国人民万岁</param><result name="success">/WEB-INF/page/message.jsp</result></action></package></struts>

message.jsp页面就会显示"中国人民万岁"
