Cache Evict Verification

Question

I use Redis as a cache store in spring boot using @Cachable annotation and evict it programitically using:

cacheManager.getCache(cacheName).clear()

The eviction process works fine. I need to add additional check after eviction that if cache entries still exist, and then perform some alert operation. For that, I need to get the Cache, check # of entries etc. I am trying the following way, but unable to retrieve anything:

cacheManager.getCache(cacheName).getNativeCache()

Is there any way to check if that Cache (Redis Cache) is a valid Cache and can contain keys/values.

Answer 1

cacheManager.getCacheNames()

This returns all the caches present at the moment. You can check if your evicted cache is present anymore or not and then perform alert operation.
