Interface AlhUserIdResolver

Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface AlhUserIdResolver
Strategy for extracting the current user id to populate AlhMdcKeys.USER_ID.

Provide a @Bean AlhUserIdResolver to override the default behavior. The default implementation returns "anonymous" for every request — apps that use Spring Security typically want to plug in something like: 


 @Bean
 AlhUserIdResolver alhUserIdResolver() {
     return req -> {
         var auth = SecurityContextHolder.getContext().getAuthentication();
         if (auth != null && auth.getPrincipal() instanceof Long userId) {
             return String.valueOf(userId);
         }
         return "anonymous";
     };
 }
