Using the Struts2 url and param tags... 使用Struts2 url和param标签...

Currently you have this: <s:url action="Hfddisp2"/><s:param name="ad_ref_no" value="% {ad_ref_no}" /> Note that the param tag is not nested inside the url tag. 当前，您具有： <s:url action="Hfddisp2"/><s:param name="ad_ref_no" value="% {ad_ref_no}" />请注意，param标签未嵌套在url标签内。

You could write this: <s:url action="Hfddisp2"><s:param name="ad_ref_no"/></s:url> 您可以这样写： <s:url action="Hfddisp2"><s:param name="ad_ref_no"/></s:url>

Note in the above that the param tags value attribute is omitted because it defaults to resolving the name provided. 在上面请注意，由于默认情况下解析参数名称，因此省略了param标签value属性。

With several attributes using a variable can make things clearer: 通过使用几个属性可以使变量更清楚：

<s:url var="myurl" action="Hfddisp2">
   <s:param name="ad_ref_no"/>
</s:url>

Then later where ever you need it: 然后在以后您需要的地方：

<s:property value="#myurl"/>

Also you should be able to include all the parameters in the current url into the new url by saying: 您还应该能够说出当前URL中的所有参数到新URL中：

<s:url action="Hfddisp2" includeParams="get"/>

For more information always consult the tag reference http://struts.apache.org/2.3.1.2/docs/tag-reference.html 有关更多信息，请始终查阅标签参考http://struts.apache.org/2.3.1.2/docs/tag-reference.html
