1.導包：解壓struts-2.3.24-all.zip的壓縮文件，解壓後如圖：
lib下爲所有Struts2的相關jar包，但是不一定是必需的，所以我們解壓apps包下的struts2-blank.war，解壓後查看struts-2.3.24\apps\struts2-blank\WEB-INF\lib路徑下的包，爲Struts2的核心jar包，如圖：
2.編寫Action類
public class HelloAction {
public String hello(){
System.out.println("hello world!!!");
return "success";
}
}3.編寫配置文件struts.xml
<?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="hello" namespace="/hello" extends="struts-default">
<action name="HelloAction" class="com.milan.struts2.action.HelloAction" method="hello">
<result name="success">/hello.jsp</result>
</action>
</package>
</struts><%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
success!!!
</body>
</html>5.在web.xml中配置過濾器
<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>6.運行項目，在地址欄輸入網址如下http://localhost:8080/Strust2/hello/HelloAction，結果如下
控制檯會輸出打印 hello world!!!
頁面顯示success!!!
