Clearly, there are plenty of caching products out there that you can use as a backing store. For those that do not support JSR-107 you need to provide a CacheManager and a Cache implementation. This may sound harder than it is, since, in practice, the classes tend to be simple adapters that map the caching abstraction framework on top of the storage API, as the Caffeine classes do. Most CacheManager classes can use the classes in the org.springframework.cache.support package (such as AbstractCacheManager which takes care of the boiler-plate code, leaving only the actual mapping to be completed).spring-doc.cn
