It will not work because those are Reactive API not Coroutines ones (if you do nothing with a Mono the demand is never triggered). I have not created Coroutines extensions for that yet but feel free to create an issue on https://github.com/spring-projects/spring-framework/issues. That said, why don't yu just return a value as usually done with the annotation based programming model ?
