[s2] Interceptor init() being called multiple times per hit
I was working on a custom interceptor that would use the init() method to
configure itself. After some analysis I realized that the init() method was
being called multiple times per action invocation. So, I made a very simple
interceptor to test to make sure I wasn¹t crazy about this.
package net.vitarara.quadran.core.web.menu;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.Interceptor;
public class TestInterceptor implements Interceptor {
public static int initCount = 0;
public void destroy () { }
public void init () {
System.err.println ("BEGIN: TestInterceptor.init()");
TestInterceptor.initCount = TestInterceptor.initCount + 1;
System.err.println ("TestInterceptor.initCount = " +
TestInterceptor.initCount);
System.err.println ("TestInterceptor = " + this.toString () );
System.err.println ("END: TestInterceptor.init()");
}
public String intercept (ActionInvocation invocation) throws Exception {
System.err.println ("BEGIN: TestInterceptor.intercept()");
String result = invocation.invoke ();
System.err.println ("END: TestInterceptor.intercept()");
return result;
}
}
Here is the struts.xml portion defining the interceptor and the stack:
<interceptors>
<interceptor name="qmenu" class="qMenuInterceptor" />
<interceptor name="testInterceptor"
class="net.vitarara.quadran.core.web.menu.TestInterceptor" />
<interceptor-stack name="defaultStack">
<interceptor-ref name="servlet-config" />
<interceptor-ref name="params" />
<interceptor-ref name="prepare" />
<interceptor-ref name="chain" />
<interceptor-ref name="model-driven" />
<!-- <interceptor-ref name="component" /> -->
<interceptor-ref name="fileUpload" />
<interceptor-ref name="static-params" />
<interceptor-ref name="params" />
<interceptor-ref name="conversionError" />
<interceptor-ref name="validation" />
<interceptor-ref name="workflow" />
<!-- <interceptor-ref name="qmenu" /> -->
<interceptor-ref name="testInterceptor" />
</interceptor-stack>
</interceptors>
Here's the log output:

The ! marks are in the actions execute() method.
Looking at this log output I have a few questions:
1. It looks to me that the TestInterceptor is being instantiated multiple
times. Why?
2. Why is are the various struts xml files being parsed multiple times for a
single action invocation?
Thanks,
Mark

I'm using struts2-all-2.0.1.jar, which I downloaded about a week ago. I'm
trying to track just behind the bleeding edge on s2.

I understood the struts-default.xml, struts-plugin.xml, struts.xml process,
but didn't think they needed to be read over and over again. Do you think
the multiple initing of the Interceptor is due to the reload of the xml
files?
Thank, especially for replying on a Sunday,

Well, first, what version of Struts 2 are you using? My guess is you
are using Struts 2.0.0, which contained a bug where the configuration
would be reloaded multiple times in a request. As for your question
why various struts files are loaded, that is how the new plugin system
works. First, struts-default.xml, in the Struts jar, is loaded.
Then, all struts-plugin.xml files are loaded from the plugin jars.
Finally, struts.xml is loaded for your application.

I'm not using an action tag. So, that shouldn't be the issue.

OK, I checked out the 2.0.2 trunk, using:
svn checkout http://svn.apache.org/repos/asf/struts/struts2/trunk
struts2-parent
Then I built it using maven and I'm using the following two jars:
./api/target/struts2-api-2.0.2-SNAPSHOT.jar
./core/target/struts2-core-2.0.2-SNAPSHOT.jar
This is what I'm seeing in my log:

So, it looks to me like the interceptor is still being init'ed multiple
times.

Ok, I should have fixed the configuration files reloading too many
times. Unfortunately, if you use the action tag, they will still
reload, as that tag doesn't fully use the ActionContext instance from
the request (where the flag to not reload is stored).
If you can, check out trunk and ensure that the problem has been fixed for you.
