结构：
HelloWorldAction.java
package com.struts2.test; public class HelloWorldAction { private String name; public String execute() throws Exception { return "success"; } public String getName() { return name; } public void setName(String name) { this.name = name; } }
web.xml提供任何Web应用程序的入口点:
<display-name>Struts 2</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>//不写，默认为index.jsp
</welcome-file-list>

插播一条：struts.xml可以包含多个struts.xml
<?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="struts1.xml"/> <include file="struts2.xml"/> <include file="struts3.xml"/> </struts>
logging.properties：
