Spring Boot Measure Execution Time using Spring AOP

application.properties

aspect.enabled=true

ExecutionTimeAdvice.java

@Aspect
@Component
@Slf4j
@ConditionalOnExpression("${aspect.enabled:true}")
public class ExecutionTimeAdvice {

    @Around("@annotation(TrackExecutionTime)")
    public Object executionTime(ProceedingJoinPoint point) throws Throwable {
        long startTime = System.currentTimeMillis();
        Object object = point.proceed();
        long endtime = System.currentTimeMillis();
        log.info("Class Name: "+ point.getSignature().getDeclaringTypeName() +". Method Name: "+ point.getSignature().getName() + ". Time taken for Execution is : " + (endtime-startTime) +"ms");
        return object;
    }
}

MessageService.java

@Service
public class MessageService {

    @TrackExecutionTime
    @Override
    public List<AlbumEntity> getMessage() {
      return "Hello message";
    }
    
}

TrackExecutionTime.java

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface TrackExecutionTime {
}

Thanks a lot

I have a method marked with @PostConstruct. Adding @TrackExecutionTime does not work here. Any idea why, and what could be done to solve this?
