I've a simple spring application with some beans and one aspect. I'm using Java-config. I've tried to run the project within IntelliJ.
The code compiles without error but the @Before- and @After-advices are not called. I read some questions and answers here, but I was not able to find the error. Any suggestions ..?
mvn dependency:tree shows:

@Aspect-annotated class:
...
@Aspect
@Component
public class Demo {
@Pointcut("execution(* de.steve72.spring.lektion07.springidol.Performer.perform(..))")
public void sayHalloAspect() {}
@Before("sayHalloAspect()")
public void takeSeats(){
System.out.println("the audience is taking their seats");
}
@After("sayHalloAspect()")
public void jump() {

}
}
The Performer interface:
...
public interface Performer {
void perform();
}
The Juggler class:
...
@Component
public class Juggler implements Performer {
private final int BEANBAGCOUNT = 3;
private int beanBag = BEANBAGCOUNT;
public Juggler() {
}
public Juggler(int beanBag) {
this.beanBag = beanBag;
}
@Override
public void perform() {
System.out.println("juggling with " + beanBag + " beanbags");
}
}
The main class:
public class MainAppLektion07 {
public static void main(String[] args) {
AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext();
ctx.register(AppConfig.class);
ctx.register(PerformerConfig.class);
ctx.refresh();
Performer juggler = (Performer)ctx.getBean("getJuggler");
juggler.perform();
}
}
The application config:
@Configuration
@EnableAspectJAutoProxy
public class AppConfig {
}
The performer config:
@Configuration
public class PerformerConfig {
@Bean
public Performer getJuggler() {
return new Juggler();
}
@Bean
public Performer getInstrumentalist() {
return new Instrumentalist();
}
}
I forgot the spring-aop.xml:
