3：在动态web工程的src下创建Struts.xml文件

<?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>
    	
    	<constant name="struts.i18n.encoding" value="UTF-8"></constant>
    	
    	<constant name="struts.action.extension" value="do"></constant>
    	
    	<constant name="struts.devMode" value="true"></constant>
    	
    <package name="strut" namespace="/struts" extends="struts-default" >
    		
    <action name="testaction" class="cn.itheima.struts.test" method="test_01" >
    			
    			<result name="success" >/struts/test.jsp</result>
    </action>
    </package>
    
    	
    </struts>

4：创建一个action类

package cn.csdn.struts;
    
    public class test {
       public String test_01(){
    	   System.out.println("hello world!");
    	   return "success";
       }
    }

5：在web.xml中配置Struts2的核心配置文件

<?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_2_5.xsd" id="WebApp_ID" version="2.5">
      <display-name>Struts2</display-name>
      
      <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>/*</url-pattern>
      </filter-mapping>
      <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
      </welcome-file-list>
    </web-app>

6：在webcontent下创建一个Struts的文件包里面保存test.jsp文件

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
    <html>
    <head>
    <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
        pageEncoding="ISO-8859-1"%>
    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
    <title>test</title>
    </head>
    <body>
    <h1>hello world!</h1>
    </body>
    </html>

7：在Tomcat中运行该项目，然后打开浏览器，在地址栏中输入：http://localhost:8080/Struts2Demo/Struts/HelloWorld
