I was trying to find some examples and evidence if Spring 4.0.3 version support caffeine cache integration? If yes, what caffeine cache version is supported for Spring 4.0.3?

CodePudding user response：

Support was added in Spring Framework 4.3 and in Spring Boot 1.4. Previously you could use the Guava provider, which was the baseline for Caffeine's. That will likely be a good approach until you are ready to upgrade. If you really need to use Caffeine for performance reasons then you might try this alternative integration.
