Quarkus Rest Client and OAuth2

Question

I have a secured micro service that is calling another secured micro service. Both services have service accounts in Keycloak. How can I configure the 1st service to automatically obtain access token from keycloak when calling the 2nd service? It's a simple service to service communication. Does the Quarkus Rest client have an API to do this? If not, how can I do that with the vert.x rest client?

Answer 1

I was able to make this work by extending the javax.ws.rs.client.ClientRequestFilter. Unfortunately I had to write my own OAuth2 logic in order to manage the access token between the requests. I hope that in the future Quarkus would provide an alternative to org.springframework.security.oauth2.client.OAuth2RestTemplate
