Struts2中有关struts-default.xml,struts.xml,struts.properties文件详解

1） struts-default.xml

这个文件是struts2框架默认加载的配置文件。它定义struts2一些核心的bean和拦截器。

2） struts.xml

该文件也是struts2框架自动加载的文件，在这个文件中可以定义一些自己的action,interceptor，package等，该文件的package 通常继承struts-default包。下面是这个文件的格式。


<?xml version="1.0" encoding="GBK"?>

<!-- 下面指定Struts 2配置文件的DTD信息 -->

<!DOCTYPE struts PUBLIC


"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"


"http://struts.apache.org/dtds/struts-2.0.dtd">

<!-- struts是Struts 2配置文件的根元素 -->

<struts>


<!-- 下面元素可以出现0次，也可以无限多次 -->

<constant name="" value="" />

<!-- 下面元素可以出现0次，也可以无限多次 -->

<bean type="" name="" class="" scope="" static="" optional="" />


<!-- 下面元素可以出现0次，也可以无限多次 -->

<include file="" />


<!-- package元素是Struts配置文件的核心，该元素可以出现0次，或者无限多次 -->

<package name="必填的包名" extends="" namespace

这是网上抄来的，人家有没有完整的，我也没办法了，有多少我就抄了多少。
