篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Struts2--struts.xml详解相关的知识，希望对你有一定的参考价值。
通常，struts.xml文件都会继承一个struts-default.xml文件通过一些基本的拦截器来提供一些基本的配置设置之类的。
配置例：
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE struts PUBLIC 3 "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN" 4 "http://struts.apache.org/dtds/struts-2.5.dtd"> 5 6 <struts> 7 <!-- 开启debug模式，会自动加载配置文件等等，不用每次更改了配置文件就去重新启动下服务器 --> 8 <constant name="struts.devMode" value="true" /> 9 10 <package name="test" namespace="/student" extends="struts-default"> 11 <action name="show" method="showStu" class="com.fuwh.demo.Show"> 12 <result name="success">hello.jsp</result> 13 14 </action> 15 16 </package> 17 18 </struts>
struts-default.xml的详细内容
