    - #### cacheNames

          public abstract String[] cacheNames

      Names of the default caches to consider for caching operations defined in the annotated class.

      If none is set at the operation level, these are used instead of the default.

      May be used to determine the target cache (or caches), matching the qualifier value or the bean names of a specific bean definition.

      默认值:
        {}

  - - #### keyGenerator

          public abstract String keyGenerator

      The bean name of the default `KeyGenerator` to use for the class.

      If none is set at the operation level, this one is used instead of the default.

      The key generator is mutually exclusive with the use of a custom key. When such key is defined for the operation, the value of this key generator is ignored.

      默认值:
        ""

  - - #### cacheManager

          public abstract String cacheManager

      The bean name of the custom `CacheManager` to use to create a default `CacheResolver` if none is set already.

      If no resolver and no cache manager are set at the operation level, and no cache resolver is set via `cacheResolver()`, this one is used instead of the default.

  - - #### cacheResolver

          public abstract String cacheResolver

      The bean name of the custom `CacheResolver` to use.

      If no resolver and no cache manager are set at the operation level, this one is used instead of the default.
