Struts2 dynamic parameter name in redirect-action
提问by fmpdmb
I'm successfully using a redirect-action for one of my struts2 mapping files as follows:
我成功地为我的 struts2 映射文件之一使用了重定向操作，如下所示：
<action name="setAsCurrentCart" class="com.fmp.MyAction">
<result name="success" type="redirect-action">
<param name="actionName">myOtherAction</param>
<param name="foo">${foo}</param>
</result>
<interceptor-ref name="defaultComponentStack"/>
</action>
Here's what I want to do though:
不过，这就是我想要做的：
<action name="setAsCurrentCart" class="com.fmp.MyAction">
<result name="success" type="redirect-action">
<param name="actionName">myOtherAction</param>
<param name="${dynamicParameterName}">${dynamicParameterValue}</param>
</result>
<interceptor-ref name="defaultComponentStack"/>
</action>
In other words, I want the name of the parameter that I'm passing to be dynamic. Does anyone know if this is possible?
换句话说，我希望我传递的参数的名称是动态的。有谁知道这是否可能？

Actually, that doesn't work. However, I was able to get this working doing the following:
实际上，这行不通。但是，我能够执行以下操作：
<action name="setAsCurrentCart" class="com.fmp.MyAction">
<result name="success" type="redirect-action">
<param name="actionName">myOtherAction</param>
<param name="${dynamicParameterName}">${dynamicParameterValue}</param>
</result>
</action>
I had just assumed it wouldn't work.
我只是认为它行不通。

could you do this instead?
你可以这样做吗？
<action name="setAsCurrentCart" class="com.fmp.MyAction">
<result name="success" type="redirect-action">
<param name="actionName">myOtherAction</param>
<param name="paramName">${dynamicParameterName}</param>
<param name="paramValue">${dynamicParameterValue}</param>
</result>
</action>
