是否可以在struts2配置文件中编写任何没有任何结果的操作

Question

Is it possible to write any action without any result in struts2 config file ? like

 < action name="showResult" class="com.mmi.webInterface.ShowResultAction"/>

but in stuts1.x it is possible to write any action without any forward result. like

< action path="/JsonResponse" type="com.mmi.webInterface.JsonResponseAction"
  validate="false"/>

my question is that how can i write any action without any result in struts 2 config file? because i have to use Ajax on the same page so no need of any result in action.

Answer 1

Yes you can write it like :

<action name="ActionName" class="ClassName" method="methodName" />

We are using such actions in our application, where there is no need to display a page as a result. It works fine.

Answer 2

Specify dummy locations. For example,

<action name="showResult" class="com.mmi.webInterface.ShowResultAction">
    <result name="success">dummy</result>
</action>

Answer 3

this should work.

<action name="actionName" class="ClassName" method="methodName"> </action>

The method methodName should be of type void else you'd get an error saying that no result is defined for this action.

hope it helps.
