Spring boot urls not accessable

[rpomeroy]

The current spring-boot/Vaadin integration blocks all the restful urls for stuff like config/metrics/beans/autoconfig etc. Switch to https://github.com/peholmst/vaadin4spring

Learned a few things along the way on this one:

• The Spring urls that I though were blocked we actually accessable on the management port 9001. Ok, officially embarrassed
• Switching to vaadin4spring still made sense. It has nice stereotype annotations and already externalize servlet configuration. I'm hoping it will get more attention down the road since it's closer to the Vaadin and Spring guys
• Once I wired up the vaadin and gwt configuration in build.gradle and executed gradle widgetset bootRun the GWT compiler did it's magic and all was good.
• I'm still confused on navigation and url path declarations. Will experiment a bit more so I can understand it better. See

The basics of the switch to vaadin4spring is done and the build works, but there's more to do. The example uses the commercial Vaadin Charts addon. The next step it to either a) replace that with the free dCharts addon or b) see if Vaadin will provide a license for our (open source) worthy cause.

More to come...
