how to call python script from spring-cloud-stream based micro-service

Question

I am thinking of using spring-cloud-stream to building message-driven micro-service application using RabbitMQ as the broker.

I see that spring-cloud-stream is built on top of Spring-Integration(SI) and SI provides spring-integration-scripting to execute python scripts. But I don't know how to hook this up in spring-cloud-stream.

So what I want to know is when a message arrives on a queue, how can I execute a python script in turn and get the output of the script?

Any code and config example would be helpful.

Hope someone can help.

Thanks GM

For this purpose Spring Cloud Stream provides particular Processor Application.

You can just register it into your Spring Cloud Data Flow and configure it with desired script.
