Secured RSocket throws java.lang.IllegalArgumentException: Neither SslContextBuilder nor SslContext is specified

I am trying to start a secured RSocket using a certificate and its private key but I can't figure out why it throws an exception in the secure{...} statement: java.lang.IllegalArgumentException: Neither SslContextBuilder nor SslContext is specified

    RSocketFactory.receive()
        .frameDecoder(PayloadDecoder.DEFAULT)
        .acceptor { setup, sendingSocket ->
            Mono.just(
                object : AbstractRSocket() {
                    override fun requestStream(payload: Payload): Flux<Payload> {
                        val randomNumberGenerator = Random(1234)
                        val numbers = payload.dataUtf8.toInt()
                        println("Generating $numbers random numbers")
                        return IntRange(1, numbers)
                            .map { DefaultPayload.create(randomNumberGenerator.nextUInt().toString().toByteArray()) }
                            .toList().toFlux()
                    }
                })
        }
        .transport(
            TcpServerTransport.create(TcpServer.create().port(7878).secure {
                SslContextBuilder.forServer(
                    File(RequestStreamRSocket::class.java.getResource("certificate.pem").toURI()),
                    File(RequestStreamRSocket::class.java.getResource("key.pem").toURI())
                )
            })
        )
        .start()
        .block()
        ?.onClose()

Solution

  • The problem was I wasn't setting the SslContext into the SslProvider.SslContextSpec:

    .transport(
    TcpServerTransport.create(TcpServer.create().port(7878).secure {
        it.sslContext(
            SslContextBuilder.forServer(
                File(RequestStreamRSocket::class.java.getResource("certificate.pem").toURI())
                File(RequestStreamRSocket::class.java.getResource("key.pem").toURI())
            )
        )
    })
)
