How to set a timeout in Spring 5 WebFlux WebClient

To set the read and connect timeout I use the method below, because the SO_TIMEOUT option is not available for channels using NIO (and giving the warning Unknown channel option 'SO_TIMEOUT' for channel '[id: 0xa716fcb2]')

ReactorClientHttpConnector connector = new ReactorClientHttpConnector(
          options -> options.option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 2000)
                            .afterNettyContextInit(ctx -> {
                                ctx.addHandlerLast(new ReadTimeoutHandler(5000, TimeUnit.MILLISECONDS));
return WebClient.builder()
