Answered 2019-Mar-22 at 00:05

The spring-boot application you mentioned resolves and loads keycloak configuration for multi tenant based on header field i.e "realm: ORGA1".

but not sure why you are calling http://localhost:8081/multitenant

You are supposed to get token for the required tenant and then called the API by passing the right tenant in header of the request
