With Spring Boot 2.0.0.RC1, actuator endpoints must be 1) enabled and 2) exposed.
By default, all endpoints but shutdown are enabled and only health and info are exposed.
In your case, the following should work:
management.endpoints.web.expose=*
# if you'd like to expose shutdown:
# management.endpoint.shutdown.enabled=true
Note that this changes (again!) as of Spring Boot 2.0.0.RC2:
management.endpoints.web.exposure.include=*
# if you'd like to expose shutdown:
# management.endpoint.shutdown.enabled=true
In doubt, the dedicated migration guide is always up-to-date with the latest changes.
Edit
For easy copy and paste, here’s the `yaml´ versions – as of Spring Boot 2.0.0.RC2:
management:
endpoints:
web:
exposure:
include: "*"
before:
management:
endpoints:
web:
expose: "*"
