Niu b , big dog!!

Found the problem Spring Boot 3.0.0 Deprecated Spring Boot actuate

Deprecated since 3.0.0 for removal in 3.2.0 in favor of org.springframework.http.server.observation.ServerRequestObservationConvention

[bclozel]

Spring Boot Actuator is not deprecated at all.

I can't reproduce this ClassNotFoundException with a new project created on https://start.spring.io, using the web, cloud config and actuator dependencies.

Maybe your application has an invalid set of dependencies? This class indeed changed coordinates in the RC phase, but your application should use Spring Framework 6.0.2 as managed by Spring Boot. Can you provide a sample application that shows the problem?
