Spring Boot v2.5.2 - refresh endpoint is not working

Question

I am using Spring Boot v2.5.2 Microservices and trying to dynamically refresh the endpoint. I am using Spring Cloud API Gateway and have implemented security, now when I make the http://localhost:8012/actuator/busrefresh, I see only Spring Cloud API gateway has reflected the changes but other microservices doesn't.

How can we fix it?

For this microservices, the refreshbus changes works, for user service it doesn't

Answer 1

your location is http://localhost:8012/actuator/busrefresh, this is your spring gateway servere location actuator, however,when you use spring cloud gateway,have you use agent to anthor server with Unified address, maybe you can try like this "http://localhost:8012/${your server agent location}/actuator/busrefresh", hopefully it's work
