@Service public class CachingService extends Object
CachingService is a service class responsible for caching group paths for faster authentication. It uses Hazelcast as the underlying caching mechanism. This service includes methods to retrieve group paths for a user, cache the group paths if not present, flush and re-cache groups when a domain match is found, and handle concurrent access using write locks.

      Parameters:
      userId - the ID of the user
      Returns:
      a list of group paths for the user

    • flushAndReCacheMatchingGroups

      public void flushAndReCacheMatchingGroups(String userId, String domain)
      Flushes and re-caches group paths for a user if the given domain occurs in the cached groups.
      Parameters:
      userId - the ID of the user
      domain - the domain to check for

    • flushAndReCacheMatchingGroups

      public void flushAndReCacheMatchingGroups(String userId, String domain, boolean force)
      Flushes and re-caches group paths for a user if the given domain occurs in the cached groups.
      Parameters:
      userId - the ID of the user
      domain - the domain to check for
      force - force deletion of groups from cache

    • cacheGroups

      protected List<String> cacheGroups(String userId)
      Retrieves group paths for the given user ID from the OIDC service, caches them, and returns the group paths.
      Parameters:
      userId - the ID of the user
      Returns:
      a list of group paths for the user

    • flushGroupIfDomainOccurs

      public void flushGroupIfDomainOccurs(String userId, String domain, boolean force)
      Flushes the group paths from the cache if the specified domain is found in any of the group paths.
      Parameters:
      userId - the ID of the user
      domain - the domain to check for in group paths
      force - force deletion of groups from cache
