[FIXED] actuator /refresh is not being provided in SpringBoot 2.0.1

Issue

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?

Solution

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

Since Endpoints may contain sensitive information, you should carefully consider when to expose them. The following table shows the default exposure for the built-in endpoints:

so, we need to expose them manually.

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

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

We can also exclude actuator which we don't want to expose using the property management.endpoints.web.exposure.exclude= shutdown,liquibase
