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.

# Four ways to call a @Cacheable method, one of which caches nothing

Four ISBNs, two of them repeats. A working cache does 2 lookups, not 4.
|
|
|
|
this.lookup(..) -> 4 repository calls <- no caching at all
|
|
self.getObject().lookup(..) -> 2 repository calls
|
|
AopContext.currentProxy() -> 2 repository calls
|
|
a second bean calls lookup(..) -> 2 repository calls
