How to get method name in interceptor
Hi,
I'm trying to access the ActionMapping from an interceptor, like the
following test stub:
public String intercept(ActionInvocation invocation) throws Exception {
ActionMapping am=ServletActionContext.getActionMapping();
log.info("The method is "+am.getMethod());
return invocation.invoke();
}
According to the javadocs am.getMethod() should return a String (the
method), but for some reason am.getMethod() always returns null. The
am.getName() and am.getNamespace() methods seem to work correctly however.
Is there a way (that works) to extract the name of the method that is going
to be executed?

That works like a charm.
Thanks a lot.

You should be able to get it through:
invocation.getProxy().getMethod();

Hi,
It seems the url (http://strutsschool.com/downloads/downloads.action) is not
working now.
Can you please post here the logic how to get the method name in
interceptor.
Thanks,
Sudhir

Right on! Rather than bale out of the interceptor stack, do this:
<action ...>
<result name="success">${destination}</result>
and provide a get/set destination in your Action class that determines where
to go next. It's much cleaner and intuitive than burying controller logic
in the interceptor stack. Holler if you have questions, as there is more
love where this comes from.
Peace,
Scott

I'm trying to write an interceptor that makes redirecting decisions based on
an annotation on the method on that is going to be executed. Like this:
public class MyAction extends ActionSupport {
...
@SomeAnnotation(value="value")
public String list() {
...
return SUCCESS;
}
}
public class MyInterceptor extends AbstractInterceptor {
...
public String intercept(ActionInvocation invocation) throws Exception {
// check if there is an annotation on the method that is going to be
executed
// redirect based on that:
if (something) invocation.invoke()
else return "someresult";
}
}
For this reason it would be nice to get the method, or at least the name of
the method, so that the interceptor could do method.getAnnotation(
SomeAnnotation.class).

Tell me more. One thing I have learned using Struts 2 is if you think it
should be possible, it probably is! What are you trying?

Thanks. This approach works, but isn't quite as elegant as I was hoping.

download the breadcrumb
<http://strutsschool.com/downloads/downloads.action>interceptor
and look at the intercept method. You will see what's happening right away.
