struts2 中redirectAction如何傳遞參數！(轉)

struts2 action提交成功後一般會轉到某一jsp。 

但有時候需要跳到某一action，一般會用如下方法： 

Xml代碼

1. <result name="success" type="chain">actionName</result>  

<result name="success" type="chain">actionName</result>
或者 
Xml代碼

1. <result name="success" type="redirect">actionName.action</result>  

<result name="success" type="redirect">actionName.action</result>

如果這個action後面要帶參數，比如xxxAction?id=xxxx 
也可以搞定，用下面的方法： 

Xml代碼

1. <action name="updateCampaign" class="campaignAction" method="updateCampaign">  
2.     <result name="success" type="redirectAction">  
3.          viewCampaignDetail?campaignId=${campaignId}   
4.     </result>  
5. </action>  

<action name="updateCampaign" class="campaignAction" method="updateCampaign"> <result name="success" type="redirectAction"> viewCampaignDetail?campaignId=${campaignId} </result></action>
或者 
Xml代碼

1. <action name="updateCampaign" class="campaignAction" method="updateCampaign">  
2.     <result name="success" type="redirectAction">  
3.         <param name="actionName">viewCampaignDetail</param>  
4.         <param name="campaignId">${campaignId}</param>  
5.     </result>  
6. </action>
