Spring Cloud Stream connection with RabbitMQ

Question

have a simple Spring-Cloud-Stream project that I try to connect with RabbitMQ, It says its connected but It\'s not working. Did I do something wrong in the code?

Answer 1

To setup spring cloud stream with rabbitmq binder implementation you need to configure this in your pom.xml 1.

 <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>
 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
 </dependency>

then you define this in your application.properties/yaml

spring:
    cloud:
        stream:
            bindings:
                greetingChannel
                    destination: test.greeting
                    group: queue
            rabbit:
                bindings:
                    greetingChannel:
                        producer:
                            transacted: true //optional

3. EnableBinding(HelloBinding.class)
4. Inject binding and use it

helloBinding.greeting().send(MessageBuilder
                .withPayload(...)
                .build());

5. Setup of rabbitMQ properties
