is it possible to create a web interface to a spring-cloud-stream application ?
Many source (file, http, ftp) send data to an application to transform it in a common format, and to reduce development i was thinking to create a web interface where users could easily configure data transformation.
Please have a look at Spring Cloud Data Flow; perhaps the drag & drop visual designer is what you're looking for.
The designer also provides a easy mechanism to override app specific properties, including how you'd transform the incoming payload using SpEL expressions.
