Isso desde o Spring 4.3!
This commit removes GuavaCache
and support classes. Caffeine supersedes
the caching support in the Google Guava library with an actively maintained
Java 8+ version in standalone form.
As it is the only Guava feature Spring framework integrates with, this commit removes effectively any reference to Guava.
