How to Implement MultiTenancy with Spring Boot and Keycloak 

Secure your web application using different Keycloak realms in a single Keycloak instance.
In some cases, we need to secure a single web application with different realms. This concept is called multi-tenancy. The realms can be located on a single or different Keycloak instance. While it's easier to have a single realm per app, it could be costly as you have to host them on different servers.
Keycloak makes it possible by offering a config resolver that can be customized and where the Keycloak adapter config can be loaded and initialized. The configuration file from different realms will be saved in the project and loaded depending on a parameter. The realm name can be defined in the query parameter, header, or for this blog in the path parameter.
