都容易忘记
<result name="goOpPolicy" type="redirect">queryPolicy.action?aaaa=${#request.aaa}</result>
request.setAttribute("aaa","what");即可
或者
queryPolicy.action?aaaa=${id} queryPolicy.action?aaaa=${aaa.id} action里有setget方法的属性
或者
<action name="goAgainChUp" class="changeTktAction" method="goAgainCheckChOrUp">
<result name="success" type="redirectAction">
<param name="namespace">/chOrder</param>
<param name="actionName">prepareDateChange</param>
<param name="cpnid">${cpnid}</param>
</result>
</action>
