An example of Spring + Vaadin 7

I’ve been beating my head on the desk trying to figure out the proper way to integrate Vaadin 7 with Spring. There are numerous outdated blog posts and a few wiki entries, but most point to either Vaadin 6 or earlier versions of Vaadin 7 and they no longer work.

Can someone
point me to an example of how to accomplish this? Your help is greatly appreciated!
