I'm trying to create a profiling performance of controller classes. I saw that Spring AOP offers PerformanceMonitoringInterceptor working with AspectJ expression.
In Spring AOP, a pointcut work instead of cflow expression is ControlFlowPointcut.
Nevertheless, when combined with DefaultPointcutAdvisor. The application failed to initialize when generating CGLIB subclass.
@Configuration
@EnableAspectJAutoProxy
public class AopConfiguration {
//...
@Bean
public Advisor performanceMonitorAdvisor() {
PerformanceMonitorInterceptor interceptor = new PerformanceMonitorInterceptor(false);
ControlFlowPointcut pointcut = new ControlFlowPointcut(MovieController.class);
return new DefaultPointcutAdvisor(pointcut, interceptor);
}
//...
}
see below stack traces,

I've no idea if it's a bug or misunderstanding of this pointcut usage.
For more details checkout my public repository, https://github.com/Panyaprach/spring-boot-demo (Try to modify class AopConfiguration)
Comment From: jhoeller
This is due to the very broad applicability of your pointcut definition: It literally applies to every bean in the context, evaluating whether the given class is in the current call stack. This then fails against an arbitrary class in Spring Security that happens to be final and cannot be proxied with CGLIB (since it is not designed to ever get proxied) - but the root of the problem is that your pointcut applies to every bean in the entire context to begin with, adding expensive proxying to totally unrelated beans.
You could try to narrow your pointcut via Pointcuts.intersection or the like, filtering by target class or target annotation (e.g. all @Service beans) first and then by control flow. Only your actual target beans will be proxied then, as selected by the first filter.
That said, note that we generally advise against control flow poincuts since they are expensive at runtime. They are meant as a specific choice applying against specific target beans, and ideally to be avoided completely if you can design it differently.

Thanks for the clarification.
