Simple POC about 2 layer and distribute cache integrate with SpringCache. 1st layer using EhCache and 2nd layer using Redis with Redisson as client.
Just simplly update spring.redis.sentinel.master in application.properties and test with API in com.demo.redissondistributecache.RedissonDistributeCacheApplication and see console log.
Test:
curl localhost:8888/testCache/1
curl localhost:8888/evictTestCache/1
curl localhost:8888/clearCache
