Change context root without recompiling?

General
1

I start with Spring boot. Must I recompile to change the context root or can it be set from outside like the port can with “-Dserver.port=”. Is there a coding standard to follow to make the context root changeable from outside?

Yes, “-Dserver.contextPath=/extra” works.
