java类package cn.hb.si;import javax.servlet.http.HttpServletRequest;import com.opensymphony.xwork2.ActionSupport;public class HelloAction extends ActionSupport{private HttpServletRequest request;@Overridepublic String execute() throws Exception {// TODO Auto-generated method stubSystem.out.println("执行Action");//返回string 可以理解为视图的路径return SUCCESS;}}

web.xml配置

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">  <filter>    <filter-name>struts</filter-name>    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>  </filter>  <filter-mapping>    <filter-name>struts</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping></web-app>

struts.xml配置

<?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><!-- 首先需要配置包名 包里面可以有多个action的 --><package name="default"  namespace="/" extends="struts-default"><action name="helloWord" class="cn.hb.si.HelloAction"><result>/result.jsp</result></action></package></struts>

自己在WebRoot下面创建对应的jsp页面

访问地址

http://localhost:8080//Struts2_1zixue/helloWord.action
