Spring Boot Cache

Wraps Spring Boot's caching abstraction with support for Caffeine, Redis, and EhCache. You get a six-step workflow covering dependencies, @EnableCaching setup, method annotations (@Cacheable, @CachePut, @CacheEvict), TTL configuration, SpEL key expressions, and Actuator metrics validation. Includes guard clauses for conditional caching and examples of common eviction patterns. The troubleshooting section correctly calls out the proxy gotcha where self-invocation bypasses the cache, which trips up a lot of people. References include curated Spring docs excerpts and end-to-end test examples. Best used when you need to add caching to service methods and want concrete patterns instead of reading the full Spring documentation.
