1复制HeadFirstStruts2chapter02-03，改名：HeadFirstStruts2chapter02-04，修改web project settings
2修改struts.xml文件，<include>标签，模拟车辆和资产模块
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
<include file="cheliang.xml"></include>
<include file="zichan.xml"></include>
</struts>
3新建chenliang.xml文件，zichan.xml文件
chenliang.xml如下：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
<package name="cheliang" namespace="/cheliang" extends="struts-default">
    <action name="cheliang" class="com.cruise.action.CheliangAction">
       <result name="success">${pageContext.request.contextPath}/success.jsp</result>
    </action>
</package>
</struts>
zichan.xml文件如下：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
<package name="zichan" namespace="/zichan" extends="struts-default">
    <action name="zichan" class="com.cruise.action.ZichanAction">
       <result name="success">${pageContext.request.contextPath}/success.jsp</result>
    </action>
</package>
</struts>
4新建ChenliangAction和ZichanAction，删除其他多余的Action
ChenliangAction如下：
package com.cruise.action;

import com.opensymphony.xwork2.Action;

public class CheliangAction implements Action{

    @Override
    public String execute() throws Exception {
       System.out.println("CheliangAction 执行了");
       return "success";
    }
}
ZichanAction如下：
package com.cruise.action;

import com.opensymphony.xwork2.Action;

public class ZichanAction implements Action{

    @Override
    public String execute() throws Exception {
       System.out.println("ZichanAction 执行了");
       return "success";
    }
}
