SKILL.md

Annotation-driven caching abstraction for Spring Boot service methods with multi-provider support.

Supports multiple cache providers (ConcurrentMap, Caffeine, Redis, Ehcache, JCache) via pluggable CacheManager beans without changing business code

Provides @Cacheable, @CachePut, @CacheEvict, and @Caching annotations with SpEL-based key generation, conditional caching, and synchronization control

Includes configuration patterns for TTL, capacity limits, and scheduled eviction; integrates with Spring Actuator for cache hit/miss metrics

Covers cache key strategies, multi-level consistency, reactive type caching, and best practices for testing and production observability

Spring Boot Cache Abstraction

Overview

6-step workflow for enabling cache abstraction, configuring providers (Caffeine,
Redis, Ehcache), annotating service methods, and validating behavior in
Spring Boot 3.5+ applications. Apply @Cacheable for reads, @CachePut for
writes, @CacheEvict for deletions. Configure TTL/eviction policies and expose
metrics via Actuator.

When to Use

Add @Cacheable, @CachePut, or @CacheEvict to service methods.

Configure Caffeine, Redis, or Ehcache with TTL and capacity policies.

Implement eviction strategies for stale data.

Diagnose cache misses or invalidation issues.

Expose hit/miss metrics via Actuator or Micrometer.
