A sample project to demonstrate Spring Cloud Stream (Source => Processor => Sink) asynchronous communication

• The project is configured to run with profiles :

• rabbit (Rabbit Binder)
• kafka (Kafka Binder)
• artemis (ActiveMQ Artemis Binder)

• Java 8
• Maven 3
• Spring Boot: 1.5.9.RELEASE
• RabbitMQ 3.7.2
• Apache Kafka Client 0.10.2
• ActiveMQ Artemis 2.4.0

• The following figure describe the global overview of the pipeline

$ ${publisher} mvn spring-boot:run -Dspring.profiles.active=rabbit
$ ${processor} mvn spring-boot:run -Dspring.profiles.active=rabbit
$ ${subscriber} mvn spring-boot:run -Dspring.profiles.active=rabbit

$ ${publisher} mvn spring-boot:run -Dspring.profiles.active=kafka
$ ${processor} mvn spring-boot:run -Dspring.profiles.active=kafka
$ ${subscriber} mvn spring-boot:run -Dspring.profiles.active=kafka

$ ${publisher} mvn spring-boot:run -Dspring.profiles.active=artemis
$ ${processor} mvn spring-boot:run -Dspring.profiles.active=artemis
$ ${subscriber} mvn spring-boot:run -Dspring.profiles.active=artemis

1. Add Pojo Support
2. Add Docker Compose file for Kafka/Rabbit/Artemis
3. Add Support to ActiveMQ Artemis 2.4.0 through Artemis binder
4. [Optional] Upgrade to Spring Boot 2.0.0.RC1 and Kafka Client 1.0.0 (fixed in spring-boot-2.0.0.RC1 branch)
