Spring AOP: Getting parameters of the pointcut annotation

Bellow I'll add a complete example of AOP implementation where I'll getting parameter from my Custom pointCut annotation, where my advice aim to calculate the time execution of a function:

1- Custom Annotation:

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

    public boolean isActivate() default false;

}

2- Controller:

@AnnotationLogExecutionTime(isActivate = true)
@PostMapping("/connection")
public HttpEntity<String> createAuthenticationToken(HttpServletRequest request,
                                                        @RequestBody AuthenticationRequest authenticationRequest) {...}

3- Advice

@Component
@Aspect
public class LoggingExecutionTimeAdvice {

    @Around("@annotation(annotationLogExecutionTime)")
    public Object logExecutionTime(ProceedingJoinPoint joinPoint, AnnotationLogExecutionTime annotationLogExecutionTime) throws Throwable {

        if(annotationLogExecutionTime.isActivate()){//Here I recover the value!!!!
            long start = System.currentTimeMillis();
            Object proceed = joinPoint.proceed();
            long executionTime = System.currentTimeMillis() - start;
            System.out.println(joinPoint.getSignature() + " executed in " + executionTime + "ms");
            return proceed;
        }
        Object proceed = joinPoint.proceed();
        return proceed;
    }
}

Explanation:

Our advice (logExecutionTime) will be excuted around (joinPoint) the function that will be annotated with AnnotationLogExecutionTime (our custom annotation) so I want to active or not this the calculation of time execution so I'll get the value from the membre of our custom annotation (which you ask about ;) )

Change the advice signature to

@Around(value="@annotation(sampleAnnotation)")
public Object display(ProceedingJoinPoint joinPoint, SampleAnnotation sampleAnnotation ) throws Throwable {
    // ...
}

and you will have access to the value in the annotation.
