actuator /refresh is not being provided in SpringBoot 2.0.1

Question

I am creating a demo project for Spring-Config-Server and Spring-Config-Client.

In SpringBoot 1.5.6.RELEASE everything is working fine.

However, when I am upgrading project to 2.0.1.RELEASE it does not provide the actuator endpoints.

The only difference bw 1.5.6 pom is version and spring-cloud.version = Dalston.SR2

Could someone please help?

Answer 1

After a bit of research, I have found the cause why the endpoints are not shown in Spring Boot 2.0 is as per docs

By default, all endpoints except for shutdown are enabled

so, we need to enable them manually.

I have added management.endpoints.web.exposure.include=* in application.properties file and now all the endpoints are back.

Note: If you are using .yml make sure to use "*" not *

Answer 2

Exposure of endpoints on HTTP is now configurable by using properties

management.endpoints.web.exposure.include
management.endpoints.web.exposure.exclude

You can expose endpoints by there ID mentioned by Actuator.

# Include all endpoints 
management.endpoints.web.exposure.include=*
# Exclude specifics 
management.endpoints.web.exposure.exclude=env

Answer 3

Even after adding the below line, wont help sometimes management.endpoints.web.exposure.include=*

Try this:- Refresh works on OPTIONS method, not with POST method for few cases.
