Spring Cloud Stream 3.0.1 adding Channel Interceptor around @Input annotation

问题

I am looking for a way to intercept the @Input annotation and add an interceptor for my Subscribable Channel

Something like below

@Around("@annotation(org.springframework.cloud.stream.annotation.Input)")
public Object interceptInput(ProceedingJoinPoint joinPoint) throws Throwable {
    LOG.debug("Intercepted @Input from method : {}", joinPoint.getSignature());

    Object returnValue = null;

    try {
        returnValue = joinPoint.proceed();
        // add the interceptor for input channel
    } catch (Exception e) {
        LOG.warn("@Input error", e);
    }

    return returnValue;
}

What can i do (near the comment) to achieve this? Any other options also are welcome
