  - ### Method Detail

    - #### setImportMetadata

          public void setImportMetadata(AnnotationMetadata importMetadata)

      Description copied from interface: `ImportAware`
      Set the annotation metadata of the importing @`Configuration` class.
      Specified by:
        `setImportMetadata` in interface `ImportAware`

    - #### reconcileCacheManager

          @PostConstruct
          protected void reconcileCacheManager()

      Determine which `CacheManager` bean to use. Prefer the result of `CachingConfigurer.cacheManager()` over any by-type matching. If none, fall back to by-type matching on `CacheManager`.
      Throws:
        `IllegalArgumentException` - if no CacheManager can be found; if more than one CachingConfigurer implementation exists; if multiple CacheManager beans and no CachingConfigurer exists to disambiguate.
