spring-cloud-function-stream-integration

This example was prepared for one of my stackoverflow question: Functional programming model bean definition and spring-cloud-function + spring-cloud-stream integration

docker run -d --rm --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3.7.15-management-alpine
./mvnw spring-boot:start
http :8080 string=1
http :8080 string=2
http :8080 string=0
# or
http :8080/process string=1
http :8080/process string=2
http :8080/process string=0
# and
echo '[0,1,1,2,3,5,8,13,21,34,55]' | http :8080/doubleIt
# or
curl -isS 0:8080/doubleIt -d '[0,1,1,2,3,5,8,13,21,34,55]' -H'Content-Type:application/json' ; echo
# and
echo 3 | http post :8080/produceIt
# or

# and
