struts2 redirect-action 传递 参数

    在做一个系统，使用struts2框架，在提交一个请求后，将获取的数据对象再要生成一个序列号，为了防止刷新生成冗余序列号，就在请求处理完成后，直接重定向到显示该信息的action中：

 

<action name="enterpreinfo" class="preinfoBusinessAction"    method="enterPreinfoSub">  
  <result name="success" type="redirect-action">  
     showpreinfo?preinfo.order_number=${preinfo.order_number}&amp;preinfo.company_name=${preinfo.company_name}   
  </result>  
 <result name="error" type="redirect">  
    <param name="location">/error.jsp</param>  
 </result>  
</action>

 

因为使用了redirect-action，所以要注意不能将showpreinf？preinfo.order_number=${preinfo.order_number}写成showpreinf.action？preinfo.order_number=${preinfo.order_number}

在这个配置文件里，多个参数的连接符使用了"&"，但XML的语法规范，应该使用"&"代替"&"，原理和HTML中的转义相同，开始没有注意，在struts分析配置文件时，总是报出这样的错误：

The reference to entity "preinfo" must end with the ';' delimiter.

<action name="editmenu" class="LunchClassPackage.MenuAction" method="UpdMenu">
    <result name="success" type="redirect-action">
        <param name="actionName">managemenu </param>
        <param name="companyId">${companyId} </param>
  </result>
</action>

官方文档：

<package name="public" extends="struts-default">
    <action name="login" class="...">
        <!-- Redirect to another namespace -->
        <result type="redirect-action">
            <param name="actionName">dashboard</param>
            <param name="namespace">/secure</param>
        </result>
    </action>
</package>

<package name="secure" extends="struts-default" namespace="/secure">
    <-- Redirect to an action in the same namespace -->
    <action name="dashboard" class="...">
        <result>dashboard.jsp</result>
        <result name="error" type="redirect-action">error</result>
    </action>

    <action name="error" class="...">
        <result>error.jsp</result>
    </action>
</package>

<package name="passingRequestParameters" extends="struts-default" namespace="/passingRequestParameters">
   <-- Pass parameters (reportType, width and height) -->
   <!--
   The redirect-action url generated will be :
   /genReport/generateReport.action?reportType=pie&width=100&height=100
   -->
   <action name="gatherReportInfo" class="...">
      <result name="showReportResult" type="redirect-action">
         <param name="actionName">generateReport</param>
         <param name="namespace">/genReport</param>
         <param name="reportType">pie</param>
         <param name="width">100</param>
         <param name="height">100</param>
      </result>
   </action>
</package>

自己的代码：

<!-- 删除文章 -->
		<action name="articleDel" class="articles.action.ArticleAction"
			method="delArticle">
			<result name="authorDelArticle" type="redirect-action">
				articlesList?do=del
			</result>
			<result name="adminDelArticle">
				/admin/articlesList.jsp
			</result>
		</action>    或用下面的代替

<result name="authorDelArticle" type="redirect">
    articlesList.action?do=del
 </result>

想解决的问题是怎么用

<param name="do"></param>成功传值，一直失败中！

警告: Caught OgnlException while setting property 'reportType' on type 'org.apache.struts2.dispatcher.ServletActionRedirectResult'.
ognl.NoSuchPropertyException: org.apache.struts2.dispatcher.ServletActionRedirectResult.reportType

上述问题是说我 没有setting property 这个属性，我去实验下。。。

Under JSP 2.1 the # character is now used by the JSP EL. 

This may cause problems with some applications that use the OGNL # operator. 

One quick-fix is to disable the JSP EL in a JSP 2.1 container (like GlassFish) by adding a jsp-config element to the web.xml

<jsp-config>
    <jsp-property-group>
      <url-pattern>*.jsp</url-pattern>
      <el-ignored>true</el-ignored>
    </jsp-property-group>
  </jsp-config>
