Question

Slow to start after upgraded to Spring 3

Answer 1

A:

I found the following in the spring source (perhaps not spring 3, but still the same class and message)

// Check to see if we have fixed interceptor to serve this method.
if (isStatic && isFrozen && fixedInterceptorMap.containsKey(key)) {
   ....
} else {
  logger.debug("Unable to apply any optimisations to advised " +
       "method " + method + " - using AOP_PROXY");
}

I'm not aware what "frozen" and "fixed" mean for intercepetors, but I think it is safe to ignore this message, since most of the advices seem to be non-frozen and non-fixed.

More importantly - it is a debug message. It should bother you if it is WARN or above. Change the log4j configuration not to show DEBUG and see what's your startup time. Perhaps the problem is elsewhere.

Answer 2

A:

I have never used CGI based proxies but JDK based proxies requires interface to do AOP. If interface is an issue, try below solution.

.

Typical struts action classes are as given below. Note that it does not implements any interface.

public class MyAction extends Action {
 public ActionForward execute(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) {
              :
 }
}

.

To resolve this issue, create an interface with execute() method same as that in Struts Action class.

public interface IAction {
 public ActionForward execute(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response);
}

.

Implement this interface in all of your actions

public class MyAction extends Action implements IAction {
 public ActionForward execute(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) {
              :
 }
}

The user said up front that he's using Struts 2; what you are describing is specific to Struts 1 and won't give him any help.

...and I decided afterwards that that wasn't worth a -1, but the darn thing won't let me undo it. I apologize.

Hmmm, Jim so you ate some of my points huh! Never mind, I'll earn more later, be careful in future though :-)

Answer 3

A:

Try increasing the heap size for tomcat. Spring 3.0 has been known to use more memory than 2.X

Answer 4

A:

Assuming that you are not intrested to advise any of the methods listed in your debug log and depending on which logging framework you use, change the log level of package you are not intrested in to INFO or higher.

For example if you are using LOG4J

log4j.logger.org.springframework=INFO

This will clean up all the clutter in your log and hence improve startup performance

Answer 5

+1 A:

On the surface it actually looks like an AOPConfig issue. Are you using any Aspects ? Obviously it is trying to intercept a method call.

It is complaining directly about and AOPConfig exception so there must be something going on with the AOP side of things.

Either you introduced the bug by using AOP or you have not upgraded to Spring 3 correctly and there are issues with the AOP useage built into Spring 3 ie your config is fishy.

Check the Spring configs and ensure you have upgraded correctly.

Note: it looks like you are using autowire in Spring, which means some part of your config might not be autowiring correctly according to the Spring rules.
