public interface CachingConfigurer
Interface to be implemented by @

classes annotated with @EnableCaching
that wish or need to specify
explicitly how caches are resolved and how keys are generated for annotation-driven
cache management.

Method Details
-
cacheManager
Return the cache manager bean to use for annotation-driven cache management. A defaultCacheResolver
will be initialized behind the scenes with this cache manager. For more fine-grained management of the cache resolution, consider setting theCacheResolver
directly.Implementations must explicitly declare
@Bean
so that the cache manager participates in the lifecycle of the context, e.g.@Configuration @EnableCaching class AppConfig implements CachingConfigurer { @Bean // important! @Override CacheManager cacheManager() { // configure and return CacheManager instance } // ... }
See @EnableCaching
for more complete examples. -
cacheResolver
Return theCacheResolver
bean to use to resolve regular caches for annotation-driven cache management. This is an alternative and more powerful option of specifying theCacheManager
to use.If both a
cacheManager()
andcacheResolver()
are set, the cache manager is ignored.Implementations must explicitly declare
@Bean
so that the cache resolver participates in the lifecycle of the context, e.g.@Configuration @EnableCaching class AppConfig implements CachingConfigurer { @Bean // important! @Override CacheResolver cacheResolver() { // configure and return CacheResolver instance } // ... }
SeeEnableCaching
for more complete examples. -
keyGenerator
Return the key generator bean to use for annotation-driven cache management.By default,
SimpleKeyGenerator
is used. See @EnableCaching
for more complete examples. -
errorHandler
Return theCacheErrorHandler
to use to handle cache-related errors.By default,
SimpleCacheErrorHandler
is used, which throws the exception back at the client. See @EnableCaching
for more complete examples.
