Quickstart: https://github.com/nmwael/blog/tree/master/keycloak_7_spring_boot_2 Failure message, which seems to have been a problem before: . ____ _ __ _ _ /\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ ( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \ \\/ ___)| |_)| | | | | || (_| | ) ) ) ) ' |____| .__|_| |_|_| |_\__, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: (v2.1.8.RELEASE) *************************** APPLICATION FAILED TO START *************************** Description: The bean 'httpSessionManager', defined in class path resource [com/johannesinnerbichler/personapp/SecurityConfig.class], could not be registered.
