1.新建一个 Dynamic Web Project 项目
2.配置 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>
<!-- 开启开发者模式-->
<constant name="struts.devMode" value="true"></constant>
<!--pakage标签
作用：给访问的action进行分包管理，吧配置文件按照面向对象管理
属性：name：指定包的名称，必须写，必须唯一
extends：指定当前包的父包，子包自动具备父包所指定的配置，我们的包一般都需要继承struts-default
-->
<package name="p1" extends="struts-default">
<action name="hello" class="com.action.HelloAction" method="getHello">
<result name="sucess" >/sucess.jsp</result>
</action>
<action name="hello2" class="com.action.HelloAction2" method="execute" >
<result name="success" >/sucess.jsp</result>
</action>
</package>
<!-- action的三种形式-->
<!-- <package name="user" extends="struts-default">
<action name="addUser" class="com.action.UserAction" method="addUser">
<result name="success">/sucess.jsp</result>
</action>
<action name="updateUser" class="com.action.UserAction" method="updateUser">
<result name="success">/sucess.jsp</result>
</action>
<action name="deleteUser" class="com.action.UserAction" method="deleteUser">
<result name="success">/sucess.jsp</result>
</action>
<action name="findUser" class="com.action.UserAction" method="findUser">
<result name="success">/sucess.jsp</result>
</action>
</package> -->
<!-- 使用通配符-->
<!-- <package name="user" extends="struts-default">
<action name="*" class="com.action.UserAction" method="{1}">
<result name="success">/sucess.jsp</result>
</action>
</package> -->
<!-- 开启动态调用-->
<constant name="struts.enable.DynamicMethodInvocation" value="true"></constant>
<!-- -->
<package name="user" extends="struts-default">
<action name="user" class="com.action.UserAction" >
<result name="success">/sucess.jsp</result>
</action>
</package>
</struts>

package com.action;
import com.opensymphony.xwork2.ActionSupport;
public class UserAction extends ActionSupport{
public String addUser() {
System.out.println("11111");
return "success";
}
public String updateUser() {
