public @interface EnableManagement

Builds the management endpoints into the server: health, metrics, the Prometheus view, scheduled jobs and managed beans, under /manage.

@EnableManagement
@Configuration
public class Settings { }

THIS IS A BUILD-TIME SWITCH. Without it – or cn1.management.enabled=true in application.properties or a profile’s file – the entry point never names the endpoints and the translator leaves their code out of the binary, so a packaged server has no /manage to find, whatever its profile. The development run always has them.

With it, the endpoints are on unless cn1.management.enabled=false turns them off at start-up, and outside a development profile they refuse to start without cn1.management.token, which belongs in the environment rather than in source.
