keycloak.json file in springboot application

Question

Is it necessary to have a keycloak.json file even if we have configured everything in application.properties for a spring boot application.

Answer 1

If you are using Spring Security Adapter, add bean KeycloakConfigResolver in your configuration file. It will use application.properties instead of WEB-INF/keycloack.json

@Bean
   public KeycloakConfigResolver KeycloakConfigResolver() {
      return new KeycloakSpringBootConfigResolver();
   }

Answer 2

Assuming yours spring-boot application , if you are using keycloak-spring-boot-starter spring-boot adapter, Then you have all your configurations in application.properties.
