一.導包

<dependency>
  <groupId>org.apache.struts</groupId>
  <artifactId>struts2-core</artifactId>
  <version>2.5.13</version>
</dependency>
二.配置struts.xml文件

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 
 3 <!DOCTYPE struts PUBLIC
 4         "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
 5
 
         "http://struts.apache.org/dtds/struts-2.5.dtd">
 6 <struts>
 7     <package name="default" extends="struts-default" namespace="/">
 8         <action name="demo" class="com.yztc.demo.action.DemoAction">
 9             <result name="index" >index.jsp</result>
10         </action>
11
 
     </package>
12 </struts>

三.配置web.xml文件

 1 <!DOCTYPE web-app PUBLIC
 2  "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 3  "http://java.sun.com/dtd/web-app_2_3.dtd" >
 4 
 5 <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
 6            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 7
 
            xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
 8                       http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
 9            version="3.1">
10   <filter>
11     <filter-name>struts2</filter-name>
12     <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
13   </filter>
14   <filter-mapping>
15     <filter-name>struts2</filter-name>
16     <url-pattern>/*</url-pattern>
17   </filter-mapping>
18 </web-app>

四.創建一個class繼承ActionSupport,如下:

 1 package com.yztc.demo.action;
 2 
 3 import com.opensymphony.xwork2.ActionSupport;
 4 
 5 /**
 6  * _ooOoo_
 7  * o8888888o
 8  * 88" . "88
 9  * (| -_- |)
10  * O\ = /O
11  * ___/`---‘\____
12  * .   ‘ \\| |// `.
13  * / \\||| : |||// 14  * / _||||| -:- |||||- 15  * | | \\\ - /// | |
16  * | \_| ‘‘\---/‘‘ | |
17  * \ .-\__ `-` ___/-. /
18  * ___`. .‘ /--.--\ `. . __
19  * ."" ‘< `.___\_<|>_/___.‘ >‘"".
20  * | | : `- \`.;`\ _ /`;.`/ - ` : | |
21  * \ \ `-. \_ __\ /__ _/ .-` / /
22  * ======`-.____`-.___\_____/___.-`____.-‘======
23  * `=---=‘
24  * .............................................
25  *
26  * @author bindu
27  * @date 2017-10-23 20:31
28  */
29 
30 
31 public class DemoAction extends ActionSupport {
32     @Override
33     public String execute() throws Exception {
34         System.out.println("你死不死啊!!!");
35         return "index";
36     }
37 }
