I am using ...
Spring Boot: 2.2.0.RELEASE
Spring Cloud: Hoxton.BUILD-SNAPSHOT
Spring Cloud RSocket: 0.2.0.BUILD-SNAPSHOT
Sample project: here

In my setup reservation-service-client communicates with reservation-service via RSocket and the service-gateway.

reservation-service registers with the following route metadata tags (see reservation-service/src/main/resources/application.yml):

spring:
  cloud:
    gateway:
      rsocket:
        client:
          service-name: reservation-service
          route-id: 400
          tags: 
            instance_name: reservation-service-1
            version: 1.0-RELEASE  # <-- I want to route based on that version.
          broker: 
            host: localhost
            port: 7002     

reservation-service-client declares forwarding information like that(see reservation-service-client/src/main/resources/application.yml):

spring:
  cloud:
    gateway:
      rsocket:
        client:
          service-name: reservation-service-client
          route-id: 500
          forwarding:       # Routing / forwarding hints to the Gateway broker.
            "[create.reservation.{vrsn}]":
              service_name: reservation-service
              version:      "{vrsn}-RELEASE"

... where {vrsn} is resolved to 2.0 as coded in reservation-service-client's ReservationServiceClient like so:

public Mono<ReservationConfirmation> createReservation(CreateReservationRequest request) {
    String version = "2.0";
    return rsocketRequester.route("create.reservation.{vrsn}", version) 
                    .data(request)
                    .retrieveMono(ReservationConfirmation.class)
                    .log();
  }

Thus, the client should be forwarded to a reservation-service instance of version 2.0-RELEASE (which is not available). However, that is not the case, and client is getting forwarded to a service instance of version 1.0-RELEASE.

When the client sends the request via the gateway to the service, you can see output in the gateway logs, that the forwarding metadata is properly available and {vrsn} was resolved properly as well, yet the gateway simply forwards to the reservation-service instance of version 1.0-RELEASE although the client routing metadata states otherwise.

Expected behaviour in this case (imo) would be to respond with max backpressure from the gateway since the service is not (yet) available.

To reproduce:

1. start service-gateway
2. start reservation-service
3. start reservation-service-client
4. send a POST request to http://localhost:9999/reservation/create/ReservationName (Web endpoint of client that will send the RSocket request)

Hi,

I'm using rsocket-websocket-client to connect to the gateway. However, I always get this particular exception since I do not set a routeId in my client.

java.lang.NullPointerException: null at java.base/java.util.concurrent.ConcurrentHashMap.get(ConcurrentHashMap.java:936) ~[na:na] Suppressed: reactor.core.publisher.FluxOnAssembly$OnAssemblyException: Assembly trace from producer [reactor.core.publisher.MonoDefer] : reactor.core.publisher.Mono.defer org.springframework.cloud.gateway.rsocket.filter.AbstractFilterChain.filter(AbstractFilterChain.java:104) Error has been observed at the following site(s): |_ Mono.defer ⇢ at org.springframework.cloud.gateway.rsocket.filter.AbstractFilterChain.filter(AbstractFilterChain.java:104) |_ Mono.log ⇢ at org.springframework.cloud.gateway.rsocket.socketacceptor.GatewaySocketAcceptor.accept(GatewaySocketAcceptor.java:113) |_ Mono.map ⇢ at org.springframework.cloud.gateway.rsocket.socketacceptor.GatewaySocketAcceptor.accept(GatewaySocketAcceptor.java:115) |_ Mono.then ⇢ at io.rsocket.RSocketFactory$ServerRSocketFactory$ServerStart.lambda$null$3(RSocketFactory.java:674) |_ Mono.onErrorResume ⇢ at io.rsocket.RSocketFactory$ServerRSocketFactory$ServerStart.lambda$acceptSetup$6(RSocketFactory.java:673) ...

I do not want users of the webclients to register themselves as separate microservices. How can I bypass the GatewaySocketAcceptor such that webclients are exempted from adding themselves in the RoutingTable?

Thank you in advance! And I'm terribly sorry if this is the wrong place for this type of question. I would use stackoverflow but it seems as though there is no way to accomplish what I'm looking for, currently.

My setup is as follows:

1. service-gateway is an RSocket broker-enabed SCG
2. reservation-service exposes an RSocket endpoint to create a reservation
3. reservation-service-client exposes a Web-endpoint (WebFlux-based) to POST a reservation-creation request, which will be translated into an RSocket-request. The request should traverse gateway and reach reservation-service
4. The reservation-service-client uses declarative forwarding / routing metadata in its application.yml

When running this setup, I receive the following NullPointerException in SCG:

Found routes: [[RoutingTableRoutes.RegistryRoute@45d46254 id = '1', predicate = [RoutIdPredicate 1]], [RoutingTableRoutes.RegistryRoute@294b114a id = '400', predicate = [RoutIdPredicate 400]], [RoutingTableRoutes.RegistryRoute@19d2ef80 id = '500', predicate = [RoutIdPredicate 500]]]

i have incorporated this changes as well.

Thanks.

Question:

Apparently, this incubator project was moved out of Spring Cloud Gateway.
Since I was referring to SNAPSHOT builds I am now missing the required dependencies.
Also I could not find this project in https://repo.spring.io/snapshot/org/springframework/cloud/.

How can I reference this project from Maven? And should I at all, or is this now being revised?

Thanks!

The data transmission process is similar to the following
A ------ B ----- C
--> 7(1025)
--> 2(1025)
2(1024) <--
--> 2(CANCEL)
7(1024) <--
2(11) <--

Hi @spencergibb,

rsocket-java just has version 1.0.0 released, so is there any plan to get this crucial project moving on?

Thanks for the great works to @spencergibb and all other contributors BTW.!

Sample project: here

The service-gateway uses Spring Cloud Gateway with RSocket support and reservation-service-client is an application that acts as a client to the (RSocket Broker) Gateway. In my production setup, ?reservation-service-client gets its configurations from a Spring Cloud config-server and config updates via Rabbit MQ and Spring Cloud Bus (which is why I need Spring Cloud Bus on the classpath).

Problem is: as soon as Spring Cloud Bus is on the classpath, I receive an Exception at startup of reservation-service-client which looks as follows:

This only occurs, if the following dependency is declared:

<dependency>
  <groupId>org.springframework.cloud</groupId>
  <artifactId>spring-cloud-bus</artifactId>
</dependency>

I am not sure, this exception is actually a problem but it's certainly not nice.

To reproduce:

1. start service-gateway
2. start reservation-service-client
3. To see the error disappear, comment out spring-cloud-bus dependency in reservation-service-client/pom.xml and start again,

A place to make a list of things that need to be done before a full GA release.

• Note that as of Hoxton.RELEASE these modules will be a tech preview Move to incubator until the RSocket routing/forwarding protocol extension and corresponding rsocket-java implementation is done.

• Comments with quotes from routing/forwarding extension

I'm interested in the routing table implementation - specifically to know how many routes would be typical in a spring cloud gateway deployment? If it's less than 100k, RoaringBitmap might not be the best data structure. If it's more likely to number in the tens, exactly the same idea can be implemented using a long per tag, saving a lot of space and cycles to match tags to routes. The answer is probably that it varies but usually somewhere in between the two extremes, so an adaptive mechanism would be ideal.

I am using ...
Spring Boot: 2.2.0-BUILD-SNAPSHOT
Spring Cloud: Hoxton.BUILD-SNAPSHOT
Spring Cloud RSocket: 0.2.0.BUILD-SNAPSHOT
Sample project: here

Step to reproduce:

• start gateway1
• start gateway2 with broker set to gateway1
• a pendingRSocket is created but not used.

It looks like GatewayRSocket::findRSocketOrCreatePending is calling createPending() before findRoute() complete, I think this do.

@FWinkler79 said in spring-cloud/spring-cloud-gateway#1355 :
I just saw issue #6, so I apologize if this is simply not yet implemented.

I saw @spencergibb's nice presentation on SCG and RSocket and took the liberty to fork his sample and adjust it a little for my tests.

I added two failure-scenarios to the sample, one of which I would have expected another outcome of. I modified PingService's request-channel handling to retry in case of errors.

The scenario is as follows:

1. run two gateway instances in cluster mode
2. run ping and see maximum back pressure applied from gateway
3. run pong and see how pings and pongs start flowing
4. stop pong, simulating the pong instance going down.
5. start pong again.

What I was hoping to see, is that ping receives an error, retries and again is confronted with maximum back pressure from the gateway.

What I saw instead is, that ping retries, silently keeps sending pings to the gateway cluster which seems to buffer the pings, and then forwards all of them to pong once that is up again.

I am not sure this is intended, and I am not 100% sure if maybe I have a bug in my own coding, but I think, it would be better, if the gateway sent maximum back pressure also in the case a remote service goes down. Maybe that goes into the direction of Deregistrations on disconnect in #1319?

If you want to try this out yourself, here is my adjusted fork:
https://github.com/FWinkler79/spring-cloud-gateway-rsocket-sample#failure-resiliency-2

It would be great to have this feature, as it would make it so much easier for application developers to create resilient Cloud applications - simply by properly handling back pressure (which they generally should have to anyway).

Also, having the gateway buffer the incoming requests from clients and replay them to servers once they are up again, might cause the servers to immediately go down again.

If my understanding is incorrect, please let me know.

I am using ...
Spring Boot: 2.2.0.RELEASE
Spring Cloud: Hoxton.BUILD-SNAPSHOT
Sample project: here
"Fixed" project: here

I tried to follow the presentation and declarative routing information as shown here at the Spring One conference.

There is an issue with declarative routing / forwarding information specified in application.yml of an RSocket client, if the route contains dots (.).

Above you can find a sample that consists of the following components:

1. reservation-service - an RSocket client exposing an endpoint by the route create.reservation that will be called by reservation-service-client via the gateway.
2. reservation-service-client - an RSocket client exposing a WebFlux API to receive POST requests that get translated into an RSocket request to reservation-service.
3. service-gateway - the RSocket broker-enabled SCG

With reservation-service-client's application.yml specifying the following routing metadata the gateway will fail forwarding the request with a NullPointerException since the client does not send the routing metadata properly:

spring:
  cloud:
    gateway:
      rsocket:
        client:
          forwarding:
            create.reservation:
              service_name: reservation-service
              canary: false

The issue is in the dotted syntax of the route, which in a Yaml file gets interpreted as a hierarchy.
I guess the matching between the client's called route, and the routing information in Yaml therefore fails.

A working sample is also given above, which uses dashes instead of dots.

To reproduce:

1. start service-gateway
2. start reservation-service
3. start reservation-service-client
4. Send a POST request with empty body to http://localhost:6666/reservation/create/RSocketRules

See also #1 which is related, but note that it additionally uses dynamic parts in the route.
