Integrating Spring AOP with existing Struts2 application

[ah habibi]

Hi,

We are trying to integrate Spring AOP in to our struts2 application for logging and authentication. We tried a sample struts2 app and integrated aop successfully. But when we integrated in to our actual application, we are facing some issues. It is not throwing any exceptions nor the advice is called. Looks like the proxies are not created using cglib (found using the StackTraceElement of RuntimeException).

import org.apache.log4j.Logger;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;

@Aspect
public class MyAuthenticationAspect {

	private Logger log = Logger.getLogger(getClass());

	
	@Before("execution( * initialize*(..))")
	public void log(JoinPoint jp) {
		log.info("Logging " + jp.getThis());
		System.out.println("before aspect ");
	}

	@Around("execution( * initialize*(..))")
	public Object authenticate(ProceedingJoinPoint pjp) throws Throwable {
		System.out.println("around aspect ");
		log.info("Authenticate  :: "
				+ pjp.getSignature().getDeclaringTypeName());

		return pjp.proceed();

	}

}

Would be great, if anyone could help us fix this issue.

Thanks in advance.
