AspectJ Autoproxy

[abking]

I'm learning spring (via "Spring in Action") and to that end I put together a simple app. While the DI works, the aspect does not. Following is my code, anyone see what is wrong?

package learn.spring.implementations;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;

@Aspect
public class Audience {
	public Audience() {}
	
	@Pointcut("execution(* *.perform(..))")
	public void performance() {}
	
	@Before("performance()")
	public void takeSeats() {
		System.out.println("Audience is taking their seats");
	}
	
}

package learn.spring.implementations;

import learn.spring.interfaces.Performer;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

public class Performance {
		
	public static void main(String[] args){
		ApplicationContext context = new FileSystemXmlApplicationContext("src/learn/spring/config/learn-spring.xml");
		Performer performer = (Performer) context.getBean("musician");
		performer.perform();
	}
	
}

Are your beans in the applicationcontext, both the performer and the aspect have to be in there.

...

Pointcut 'execution(* *.perform(..))' matches all methods named 'perform()' of classed from default package. I assume that your 'Performer' class belongs to the 'learn.spring.implementations' package (as 'Performance' class does), hence, no pointcut is matched.

The issue was an incorrect aspect id in the application context; upon correcting that, it worked. Thanks.
