1、创建web项目

2、添加jar包（jar包后面连同项目源码一同发布下载链接）

3、配置web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"><filter><filter-name>struts2</filter-name><filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class></filter><filter-mapping><filter-name>struts2</filter-name><url-pattern>*.htm</url-pattern></filter-mapping>  <welcome-file-list>    <welcome-file>/WEB-INF/html/index.html</welcome-file>  </welcome-file-list></web-app>

4、编写请求Action

public class HsunAction extends ActionSupport {@Overridepublic String execute() throws Exception {out.println(msg);msg = "I am coming ";out.println(msg);return SUCCESS;}public String test() throws Exception{msg = "hello test";out.println("hello test");return SUCCESS;}private String msg;public String getMsg() {return msg;}public void setMsg(String msg) {this.msg = msg;}}

5、配置struts.xml

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"><struts><!--增加struts的扩展名--><constant name="struts.action.extension" value="htm" /><package name="hsun" namespace="" extends="struts-default"><action name="hello" class="com.hsun.struts.action.HsunAction"><result name="success">/WEB-INF/html/hello.jsp</result></action><action name="test" class="com.hsun.struts.action.HsunAction" method="test"><result name="success">/WEB-INF/html/hello.jsp</result></action></package></struts>

6、返回页面 hello.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>    <title>Home</title>  </head>    <body>    Hello World! <br>    ${msg }  </body></html>

OK！SUCCESS~~~
