Questions tagged [spring-cloud-stream]

Spring Cloud Stream allows a user to develop and run messaging microservices using Spring Integration and run them locally, or in the cloud, or even on Spring Cloud Data Flow. Just add @EnableBinding and run your app as a Spring Boot app (single application context). You just need to connect to the physical broker for the bus, which is automatic if the relevant bus implementation is available on the classpath.
