Spring WebFlux: Only one connection receive subscriber allowed

    val id = it.         


        

Answer 1

I've done a very similar example here:

This router will get a geolocation from name and the with another service extract the sunrise and sunset time:

I've use the and method from Mono.

internal fun buildResponse(address: Mono) =
        address.transform(geoLocationService::fromAddress).and(this::sunriseSunset, ::LocationResponse)

internal fun sunriseSunset(geographicCoordinates: GeographicCoordinates) =
        geographicCoordinates.toMono().transform(sunriseSunsetService::fromGeographicCoordinates)
