^{Originally posted by **dwang2** April 7, 2024} I have developed a reactive security service to retrieve the current user's name using the code snippet provided below. How can I formulate a key-cache expression to asynchronously fetch the username > @Service public class SecurityService { public Mono username() { return ReactiveSecurityContextHolder.getContext() .map(securityContext -> { Authentication authentication = securityContext.getAuthentication(); return authentication != null ? authentication.getName() : null; }); } }

Given that we are using Spring version 2.7.x, could you please extend support to version 0.8.x as well? This aligns with the current version I'm using.
