cacheKeyGeneratorAttrName |
uses the built-in default cache-helper key generation, which concatenates the servlet path with key-field values, if any. |
The caching engine searches in the ServletContext for an attribute with a name equal to the value specified for this property to determine whether a customized CacheKeyGenerator implementation is used. An application may provide a customized key generator rather than using the default helper. For more information, see CacheKeyGenerator Interface |
