Redirect Action Result

Redirect Action Result : This redirect pattern is supported by Struts 2. The ActionMapper provided by the ActionMapperFactory is used to redirect the browser to a URL that invokes the specified action. You can see a simple implementation of this in the following struts 2 application. 

Redirects Dynamic Parameters: The action-redirect result takes following parameters:

• actionName
• namespace
• method
• encode
• parse
• location
• prependServletContext

parameters ------------

namespace - used to determine which namespace the action is in that we're redirecting to . If namespace is null, this defaults to the current namespace

 

<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>

<param name="转发的action的成员名">${被转发的action中变量}</param>
   <param name="fileName">${fileName}</param>
