Not sure how this is supposed to work. To be able to support
Angular's development server and Spring as a standalone application
I had to hardcode the port Spring uses.
The problem is, that Angular runs on port 4200. Angular is compiled
to static files. So I cannot dynamically add the port that is
configured for Spring. But Angular has to be able to talk to the
Spring application.
I chose port 17333, because it does not collide with the standard
Tomcat port (8080).
