Spring Cloud Stream Applications

Spring Cloud Stream Applications are Spring Boot based Spring Integration applications that provide integration with external systems. Spring Cloud Stream Applications can be used with Spring Cloud Stream to create, build, and operationalize message-driven data microservices.

Quick Start
Fork me on GitHub

Spring Cloud Stream Applications are standalone executable applications that communicate over messaging middleware such as Apache Kafka and RabbitMQ. These applications can run independently on variety of runtime platforms including: Cloud Foundry, Apache Yarn, Apache Mesos, Kubernetes, Docker, or even on your laptop.


  • Run standalone as Spring applications
  • Create streaming pipelines with data microservice applications
  • Host and consume data microservice applications as maven dependencies
  • Override configuration parameters via command-line, environment variables, or YAML file
  • Provide infrastructure to test the applications in isolation
