struts.xml配置的代码,谁能帮忙分析一下

XML code

<?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>    <constant name="struts.devMode" value="true" />    <constant name="struts.objectFactory" value="spring" />        <package name="common" extends="struts-default">        <global-results>            <result name="error">/common/miplatform_error.jsp</result>        </global-results>            <global-exception-mappings>            <exception-mapping exception="java.lang.Exception" result="error"/>        </global-exception-mappings>    </package>

这些代码是什么作用?


[解决办法]
struts.devMode
Whether Struts is in development mode or not
是否为struts开发模式

struts.objectFactory
The com.opensymphony.xwork2.ObjectFactory implementation class
com.opensymphony.xwork2.ObjectFactory接口（spring）
事务用spring


<package name="common" extends="struts-default">
<global-results>
<result name="error">/common/miplatform_error.jsp</result>
</global-results>
<global-exception-mappings>
<exception-mapping exception="java.lang.Exception" result="error"/>
</global-exception-mappings>
</package>
配置当程序报java.lang.Exception错误的时候跳转到
common/miplatform_error.jsp
