import org.springframework.cache.interceptor.CacheResolver;

Extension of CachingConfigurer for the JSR-107 implementation. 
To be implemented by classes annotated with EnableCaching that wish or need to specify explicitly how exception caches are resolved for annotation-driven cache management. Consider extending JCacheConfigurerSupport, which provides a stub implementation of all interface methods. 
See EnableCaching for general examples and context; see exceptionCacheResolver() for detailed instructions.
