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.

Actuator endpoint provided in 1.5.6.RELEASE

Mapped "{[/refresh || /refresh.json],methods=[POST]}" Mapped "{[/dump || /dump.json],methods=[GET] Mapped "{[/heapdump || /heapdump.json],methods=[GET] Mapped "{[/autoconfig || /autoconfig.json],methods=[GET] Mapped "{[/resume || /resume.json],methods=[POST]}" Mapped "{[/configprops || /configprops.json],methods=[GET] Mapped "{[/features || /features.json],methods=[GET] Mapped "{[/loggers/{name:.*}],methods=[GET] Mapped "{[/restart || /restart.json],methods=[POST]}" ...and many more

Actuator endpoint provided in 2.0.1.RELEASE

Mapped "{[/actuator/health],methods=[GET] Mapped "{[/actuator/info],methods=[GET] Mapped "{[/actuator],methods=[GET]

pom.xml : 2.0.1.RELEASE

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

Could someone please help?

Reset to default

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

Hm, that's really weird. The docs state that the endpoints are enabled by default, which was definitely not the case for me (and it seems for you too!). Perhaps the docs are wrong?
You need to understand the difference between enabled and exposed via web endpoint. Enabled endpoint is not necessarily exposed via web. Currently by default most endpoints are enabled. Most of them are also exposed via JMX, but only "info" and "health" are exposed via web (http). Documentation clearly states all of this if you read it.

refresh endpoint can be enabled to use via web (exposed via web), using this in application.yaml

management.endpoints.web.exposure.include: health,info,refresh

Spring Boot enables health and info endpoints by default. It is necessary to list them to keep them enabled.

If your application has this URL http://localhost:8181

You can send POST request to refresh

http://localhost:8181/actuator/refresh

does ur application restart when u hit localhost:8181/actuator/refresh ?
@SanjayNaik No. Context restarts.

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

Even after adding the below line, it wont help sometimes

management.endpoints.web.exposure.include=*

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

options mainly give 200. But, it works for POST only, are you sure it overrided values?

This is what I did. Enabled all the endpoints by setting

management.endpoints.web.exposure.include=*

And sent an empty request to refresh endpoint.

curl -d '{}' -H 'Content-Type: application/json' http://localhost:8000/actuator/refresh

URL http://localhost:8000/actuator/ will list all the available endpoints.

P.S.: My app is running on port 8000. On default port 8080, I am running Config server.

To enable refresh, add following properties to your application properties file

management.endpoints.web.exposure.include=health,info,refresh management.endpoint.refresh.enabled=true
