@Component public class IsOnVaultPredicate extends org.springframework.cloud.gateway.handler.predicate.AbstractRoutePredicateFactory<IsOnVaultPredicate.Config>
Predicate implementation for Spring Cloud Gateway that checks if a node is present in the vault.

This predicate examines the path of the incoming HTTP request and tries to extract a node UUID from it using a predefined regular expression. If a valid node identifier is found, it queries the MongoNodeRepositoryImpl to determine whether the corresponding node is present. The predicate returns true if the node exists in the vault, otherwise false.

Expected matching path format: any string containing "/nodes/{uuid}" where {uuid} is a valid UUID version 4.

Logging is performed for debugging purposes, indicating detection of the node ID and the result of the vault check.

Extends AbstractRoutePredicateFactory to be used as a custom route predicate in gateway routing configurations.

The inner static Config class is required for Spring Cloud Gateway custom predicate factories.

Dependencies: - MongoNodeRepositoryImpl: Used for checking node existence by ID.
