Cannot call HTTP when rsocket server is activated

[belkirdi]

I tried to make rsocket server work with my api in webflux using the spring boot 2.2.0.M2 but unfortunately the http request stopped working

[belkirdi]

what I tried to explain is that you cannot call http request when rsocket server is activated

[philwebb]

I'm afraid there's not really enough information here to tell if we have a bug or if this is a configuration issue. Please could you provide a small sample that shows what you mean?

[belkirdi]

The issue still remaining in your latest version 2.2.0.M3. Please find below a sample code of how to reproduce the bug: (I find another issue is if if I define another port than default netty the Server doesn't respond to my http and rsocket request from a client )

package com.belkirdi.issue;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import reactor.core.publisher.Flux;
import reactor.core.publisher.Mono;
import org.springframework.messaging.handler.annotation.MessageExceptionHandler;
import org.springframework.messaging.handler.annotation.MessageMapping;

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }


    @RestController
    public class RestApi {

        @GetMapping("/rest_test")
        public Mono<Boolean> sendBoolean() {
            return Mono.just(Boolean.TRUE);
        }
    }


    @Controller
    public class RSocketApi {

        @MessageExceptionHandler
        Flux<String> errorHandler(IllegalArgumentException iia) {
            return Flux.just("error");
        }

        @MessageMapping("/rs_test")
        Mono<Boolean> requestResponse() {
            return Mono.just(Boolean.TRUE);
        }
    }
}

Application.properties

Here's a sample from @linux-china: https://github.com/linux-china/rest-404-with-rsocket

[belkirdi]

Please don't forget in the case of using a different port for rsocket server. Everything stop working http and rsocket . Thanks
