Class ConcurrentMapCacheManager

java.lang.Object

org.springframework.cache.concurrent.ConcurrentMapCacheManager

All Implemented Interfaces:

CacheManager

public class ConcurrentMapCacheManager
extends Object
implements CacheManager

CacheManager implementation that lazily builds ConcurrentMapCache instances for each getCache(java.lang.String) request. Also supports a 'static' mode where the set of cache names is pre-defined through setCacheNames(java.util.Collection<java.lang.String>), with no dynamic creation of further cache regions at runtime.

Since:

3.1
