RabbitMQ Tracing Informations are missing

Describe the bug I want to use a sleuth with RabbitMQ messaging, but I can’t see the tracing informations. I generated a demo application with spring start, and add some minimal functionality, to produce a message to rabbitmq.

Sample Here are the dependencies

    <properties>
        <java.version>15</java.version>
        <spring-cloud.version>2020.0.0</spring-cloud.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-sleuth</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-stream</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-stream-binder-rabbit</artifactId>
        </dependency>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

application.yml

spring:
  # Cloud Stream
  cloud:
    stream:
      rabbit.bindings:
        ipnMessageSupplier-out-0:
          producer:
            autoBindDlq: true
            bindingRoutingKey: simplepay
            routingKeyExpression: '''simplepay'''
      bindings:
        ipnMessageSupplier-out-0:
          destination: financial
          content-type: application/json
          producer.requiredGroups: simplepay.financial
    function:
      definition: ipnMessageSupplier

  # RabbitMQ
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    username: root
    password: root

and the application java

@SpringBootApplication
public class DemoApplication {

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

    @Bean
    Supplier<String> ipnMessageSupplier() {
        return () -> "DEMO";
    }
}

@jmecsei I think having an async client that hides even the blocking queue and you just need to call send on would be the best but I’m not familiar with the reasoning behind the current solution. I’m going to ask around next week to see what can we do.
