In my previous post, I shown how to create a custom Spring Boot actuator endpoint. It could be useful to have pretty web interface to document these endpoints and allow other people to easily access your api in a pretty way. You know, I'm a girl, I like pretty things ;)

So, I chosen to use OpenApi which is usually easy to use, usually... In fact, by default, actuator endpoint are not shown with OpenApi, and it was hard to find how to do. That's why I decide to write this small post.

First of all, you'll need this dependencies :

    implementation group: 'org.springdoc', name: 'springdoc-openapi-ui', version: '1.5.0'
    implementation group: 'org.springdoc', name: 'springdoc-openapi-data-rest', version: '1.5.0'

Then, you just need to add these properties...

springdoc:
  show-actuator: true

... And you got your actuator endpoint documentation !

... And you can test your endpoints
