Accessing the parameters of the result of the stance action in the interceptor
I am using struts and spring integrated frameworks in my project. I have an interceptor before every call to the rack action. I need to access the name of my action and I do it with the following piece of code:
actionInvocation.getProxy().getActionName();
and the struts action in struts.xml:
<action name="uploadDocument" class="commonAction" method="uploadDocument">
<interceptor-ref name="sessionStack"/><interceptor-ref name="cachingStack"/>
<interceptor-ref name="basicStack"/>
<result name="success" type="stream">
<param name="contentType">text/html</param>
<param name="result">inputStream</param>
</result>
</action>
I need to access the parameters in the result tag. Is it possible?

Sure.
You can read the configuration of the result in the ResultConfig object as described here , which will display a map of its parameters as shown in the source code .
Something like:
// Get the action configuration defined in struts.xml
ActionConfig config = invocation.getProxy().getConfig();
// Get the SUCCESS result configured for that Action
ResultConfig success = config.getResults().get("success");
// Iterate the Params, friendly printing :)
for (Map.Entry<String, String> entry : success.getParams().entrySet()) {
System.out.println("<param name=\""
+ entry.getKey()
+ "\">"
+ entry.getValue()
+ "</param>");
}
