Expression Execute Spring aspects

Question

I have a problem relationing with spring aop

(edit:If my method isnt static, the code works fine)

I have this strucuture in packages:

aaa.bbb.ccc.Clase1.java
aaa.bbb.ddd.Clase2java

and i want whit aspects put point cut

and I want to put the aspect pointcut at aaa, meaning that all functions that hang from whatever package or subpackage of aaa pass through the aspect pointcut

I have this writen, but this code doesnt write in the log:

@After("execution( ¿Expression?)")
public void logAfter(JoinPoint joinPoint) {
    String clasName = joinPoint.getTarget().getClass().getName();
    String method = joinPoint.getSignature().getName();
    log.info("Empieza la funcion "+clasName +"."+ method);
}

I tried this code:

@After("execution(* aaa..*(..))")
@After("execution( aaa..*(..))")
@After("execution(* aaa.*.*(..))")

and something more, but i never achieved anything...

EDIT:

all CODE and classes:

        log.info("Empieza la funcion "+clasName +"."+ method);
    }

package aaa.bbb.conversor.conversion;

}

Main.java

ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
Conversion.conversion1(ficheroEntrada, ficheroConfiguracion);

Thanks a lot, One saludate

You cannot intercept static methods with Spring AOP. Spring AOP is proxy-based, is not like AspectJ where there are some deeper mechanisms for interception. All advices are applied to instances of classes that are managed by Spring. A static method "belongs" to a class, not to an instance of that class (you call aaa.bbb.conversor.conversion.Conversion.conversion1() not conversionInstance.conversion1() ).
