A Spring Boot 4.1.1 module whose test suite is the evidence for the article: 20 tests producing 22 transcripts under docs/output/, plus 12 documentation chapters. Findings the build pins: - @EnableCaching has no exposeProxy attribute; the widely-copied @EnableCaching(exposeProxy = true) does not compile. - Two methods sharing a cache name and an argument type share a key space, and one silently serves the other's answers. - The documented cache-provider detection order does not match CacheType's enum order in 4.1.1: COUCHBASE before INFINISPAN, and CACHE2K before CAFFEINE. - beforeInvocation = true is NOT deferred by TransactionAwareCacheManagerProxy on 7.0.9 - doEvict picks evictIfPresent, which the decorator does not intercept. - Four of five invalid declarations start a clean context and throw at the first call. - Caffeine on the classpath silently displaces the simple provider.

# @CacheEvict runs after the method - unless you ask otherwise

price("sku-1") -> 100 (stored price is 100)
|
|
|
|
updatePrice("sku-1", 250, fail=true) threw after writing the new price.
|
|
stored price now : 250
|
|
price("sku-1") : 100 <- the cache still serves the old value
|
|
reads of the real store: 1
|
|
|
|
--- beforeInvocation = true ---
|
|
price("sku-2") -> 100
|
|
updatePriceEvictFirst("sku-2", 250, fail=true) threw the same way.
|
|
price("sku-2") : 250 <- the entry went first, so the next read is honest
|
|
|
|
--- @CachePut instead: write through, no miss ---
|
|
after @CachePut, price("sku-3") -> 400
|
|
reads of the real store: 1 -> 1 <- no reload was needed
