struts2 action重定向如何传递参数

Answer 1

struts2 action提交成功后一般会转到某一jsp。 但有时候需要跳到某一action，一般会用如下方法：Xml代码<result name="success" type="chain"actionName</result <result name="success" type="chain"actionName</result或者Xml代码<result name="success" type="redirect"actionName.action</result <result name="success" type="redirect"actionName.action</result 如果这个action后面要带参数，比如xxxAction?id=xxxx 也可以搞定，用下面的方法：Xml代码<action name="updateCampaign" class="campaignAction" method="updateCampaign" <result name="success" type="redirectAction" viewCampaignDetail?campaignId=${campaignId} </result </action <action name="updateCampaign" class="campaignAction" method="updateCampaign" <result name="success" type="redirectAction" viewCampaignDetail?campaignId=${campaignId} </result</action或者Xml代码<action name="updateCampaign" class="campaignAction" method="updateCampaign" <result name="success" type="redirectAction" <param name="actionName"viewCampaignDetail</param <param name="campaignId"${campaignId}</param </result ps：传递的参数，在对应的action中必须有set方法且将值set进去
