Spring Boot Cache Abstraction

Overview

Spring Boot ships with a cache abstraction that wraps expensive service calls behind annotation-driven caches. This abstraction supports multiple cache providers (ConcurrentMap, Caffeine, Redis, Ehcache, JCache) without changing business code. The skill provides a concise workflow for enabling caching, managing cache lifecycles, and validating behavior in Spring Boot 3.5+ services.

When to Use

• Add @Cacheable, @CachePut, or @CacheEvict to Spring Boot service methods.
• Configure Caffeine, Redis, or JCache cache managers for Spring Boot.
• Diagnose cache invalidation, eviction scheduling, or cache key issues.
• Expose cache management endpoints or scheduled eviction routines.

Use trigger phrases such as "implement service caching", "configure CaffeineCacheManager", "evict caches on update", or "test Spring cache behavior" to load this skill.

Prerequisites

• Java 17+ project based on Spring Boot 3.5.x (records encouraged for DTOs).
• Dependency spring-boot-starter-cache; add provider-specific starters as needed (spring-boot-starter-data-redis, caffeine, ehcache, etc.).
• Constructor-injected services that expose deterministic method signatures.
• Observability stack (Actuator, Micrometer) when operating caches in production.

Quick Start

1. Add dependencies

   <!-- Maven -->
   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-cache</artifactId>
   </dependency>
   <dependency> <!-- Optional: Caffeine -->
       <groupId>com.github.ben-manes.caffeine</groupId>
