Answer 1

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

Answer 3

<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> 
包名为common 默认缺省设置 当发生异常java.lang.Exception时 异常页面跳转到common/miplatform_error.jsp
