一：导入jar包
二：导入struts.xml
配置struts.xml 
<struts> <constant name="struts.devMode" value="true" />
<constant name="struts.action.extension" value="do,qq"/> <package name="default" namespace="/" extends="struts-default"> <action name="hello"> <result> /hello.jsp </result> </action> </package> <!-- Add packages here --> </struts>
三:配置web.xml
(1)找web.xml
(2)关联源代码（JAVA）：
struts.jar-->properties-->Java Resources Attach-->External location-->
(3)修改内容
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> 5 6 <display-name>Struts Blank</display-name> 7 8 <filter> 9 <filter-name>struts2</filter-name> 10 <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> 11 </filter> 12 13 <filter-mapping> 14 <filter-name>struts2</filter-name> 15 <url-pattern>/*</url-pattern> 16 </filter-mapping> 17 18 </web-app>
四：新建hello.jsp
1 <%@ page language="java" contentType="text/html; charset=ISO-8859-1" 2 pageEncoding="ISO-8859-1"%> 3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 4 <html> 5 <head> 6 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> 7 <title>Insert title here</title> 8 </head> 9 <body> 10 helloStruts2!!! 11 </body> 12 </html>
五：（1）普通的JAVA类
1 package nuc.sw.action; 2 3 public class HelloAction1 { 4 public String execute() throws Exception{ 5 return "OK"; 6 } 7 }
（2）实现接口Action的类
1 package nuc.sw.action; 2 3 import com.opensymphony.xwork2.Action; 4 5 public class HelloAction2 implements Action { 6 7 @Override 8 public String execute() throws Exception { 9 // TODO Auto-generated method stub 10 return SUCCESS; 11 }public HelloAction2() { 12 // TODO Auto-generated constructor stub 13 } 14 }
（3）继承ActionSupport类
1 package nuc.sw.action; 2 3 import com.opensymphony.xwork2.ActionSupport; 4 5 public class HelloAction3 extends ActionSupport { 6 @Override 7 public String execute() throws Exception { 8 // TODO Auto-generated method stub 9 return SUCCESS; 10 } 11 }
（4）修改struts.xml
1 <package name="default" namespace="/" extends="struts-default"> 2 <action name="hello1" class="nuc.sw.action.HelloAction1" method=""> 3 <result name="OK"> 4 /hello.jsp 5 </result> 6 </action> 7 <action name="hello2" class="nuc.sw.action.HelloAction2" method=""> 8 <result name="success"> 9 /hello.jsp 10 </result> 11 </action> 12 <action name="hello3" class="nuc.sw.action.HelloAction3" method=""> 13 <result name="success"> 14 /hello.jsp 15 </result> 16 </action> 17 </package>
六：执行结果
（1）：普通的JAVA类
（2）：实现接口的Action类
（3）:继承ActionSupport类
（4）:修改action后缀名
<constant name="struts.action.extension" value="do,qq"/>
