Spring fails to pickup AOP configuration beans

Question

Error

Bean 'aopConfiguration' of type [example.config.AopConfiguration$$EnhancerBySpringCGLIB$$5e48431d] is not eligible for getting processed by all BeanPostProcessors

The following beans failed:

aopConfiguration
performanceMonitorInterceptor
performanceMonitorAdvisor

Config

@Aspect
@EnableAspectJAutoProxy
@Configuration
public class AopConfiguration {

    @Pointcut("execution(* example.service.TimestampService.findAllTimestamps(..))")
    public void monitor() {
    }

    @Bean
    public PerformanceMonitorInterceptor performanceMonitorInterceptor() {
        return new PerformanceMonitorInterceptor(false);
    }

    @Bean
    public Advisor performanceMonitorAdvisor() {
        AspectJExpressionPointcut pointcut = new AspectJExpressionPointcut();
        pointcut.setExpression("example.config.AopConfiguration.monitor()");
        return new DefaultPointcutAdvisor(pointcut, performanceMonitorInterceptor());
    }
}

application.yml

logging:
  file:
    name: log.log
  pattern:
    console: "%d{HH:mm:ss.SSS} %msg%n"
  level:
    org.springframework.web: INFO
    example.config.PerformanceMonitorInterceptor: DEBUG
    example: DEBUG

Basically no logging or trace information is put to the console.

An aspect should not be its own configuration class because the configuration is for the whole application. Use a separate class for @Configuration and let the @Aspect just be an aspect (and also make the aspect a @Component). Under the hood, proxying for configurations works differently from AOP proxies in Spring. If you are interested in the technical details, read my answer here.
