You can do it with doOnNext(), if you use DataBuffer as your reader:

public Mono selectByPost(ServerRequest request) {
  Flux requestBodyFlux = request.bodyToFlux(DataBuffer.class)
    .doOnNext(dataBuffer -> {
      if (debug ) {
        log.debug(new String(dataBuffer.asByteBuffer().array()));
      }
      Scannable.from(dataBuffer).tags().forEach(System.out::println);
    });
}

This is probably not the best way to do it, it would of course be a nice feature, if netty would provide different ways of logging the payload. Hex does have its benefits, depending on what you need to debug.
