Class DPoPProofReplayValidator.InMemoryCache

java.lang.Object

org.springframework.security.oauth2.jwt.DPoPProofReplayValidator.InMemoryCache

All Implemented Interfaces:

org.springframework.cache.Cache

Enclosing class:

DPoPProofReplayValidator

public static final class DPoPProofReplayValidator.InMemoryCache
extends Object
implements org.springframework.cache.Cache

An in-memory Cache implementation backed by a ConcurrentHashMap.

NOTE: This implementation has limitations as it only works in a single-node setup. For production (and clustered) environments, it is recommended to use a distributed Cache implementation (e.g. Redis, Hazelcast, etc.).

This implementation can be fine-tuned based on the following configuration settings:

• setMaxSize(int) - Sets the maximum number of entries the cache can hold. The default is 100,000.
• setMaxRequestsPerKey(int) - Sets the maximum number of requests allowed per JWK thumbprint. The default is 1000.

Since:

6.5.12
