誰かが違いを説明してもらえますか

com.googlecode.ehcache.annotations.Cacheable および org.springframework.cache.annotation.Cacheable

最初のものを2番目のものに置き換えると、どのような効果がありますか??

spring を使用してコーディングされた Web サービスで @Cacheable を使用しました

@Cacheable(value = "policyCache")
public ResponseEntity<ResponseVO> listById(@PathVariable(value = "id") )

Spring 3 introduces a new abstraction layer for caching services. The idea is to provide a set of common features, mainly annotations, to activate and manage the caches. Since it is only an abstract layer, Spring 3 caching still need a concrete implementation to work. The entry point for cache implementation is the CacheManager interface. By default 2 concrete implementation of CacheManager are provided: EhCacheCacheManager: default implementation for EhCache ConcurrentMapCacheManager: default implementation using Java ConcurrentHashMap as cache store.

With the use of com.googlecode.ehcache.annotations.Cacheable, you rely immediately on the ehCache implementation.

If you use the Spring annotations, you don't have to do any code adaptations if you want to change your cache implementation later on, so I would advise to use the latter.
