[keycloak-dev] KeycloakSecurityContext is always null

Hello everyone, I do not understanding how can I correctly use KeycloakSecurityContext on a Rest service to obtain access to keycloak tokens. I tryed via httpServletRequest: KeycloakSecurityContext session = (KeycloakSecurityContext) httpServletRequest.getAttribute(KeycloakSecurityContext.class.getName()); But, my KeycloakSecurityContext is always null. I put the anotation @SecurityDomain("keycloak") on my class without success. The authentication works perfectly but, the authorization is a problem. I am trying access to KeycloakSecurityContext to work with authorization. If someone has a tip that can help me, please let me know. Regards, Mauricio.
