Vaadin 8 Upload - Complete Code

Flow
1

Hi! As I’m pretty new to Vaadin (currently using version 8), I can’t really wrap my head around the file upload issue in Vaadin 8. I tried to build a sensible and working solution using the examples and manuals I found on the web, however all of them seem incomplete and thus don’t work. Could you please provide me with a complete (more or less) code I might reuse to save my images into the Postgres? I’ll appeciate!

There is a bit old, but comprehensive example here (actually two). The other loads the file to temporary file, and other to memory buffer.

There is simple to memory buffer loading example here too
