Design pattern direction needed - background data producer

[stdunbar]

I've got a desktop deployed system that will read from a USB device and present data via Websockets to a browser UI. Additionally, I want to save the data to a cloud backend. Ultimately this seems like a good use of the Vert.x event bus with one producer and two consumers. My challenge is the USB device reader. My searches are not showing me how to start up a background process at system initialization and publish to the bus.

Can you direct me to a way to accomplish what I'm looking to do? I don't doubt that I've missed something and could use some help / direction. Thanks.

The bean can start the background process and stop it when the application termines.
