Question

I am trying to enable Hibernate Second Level Cache with using of hazelcast in client server mode.
but when i run the application i get this exception
Caused by: java.lang.ClassNotFoundException: Could not load requested class : com.hazelcast.client.cache.impl.HazelcastClientCachingProvider

this is my hibernate configuration
jpa:
default:
properties:
hibernate:
cache:
use_query_cache: false
use_second_level_cache: true
region:
factory_class: com.hazelcast.client.cache.HazelcastClientCachingProvider
[Updated]
this is my build.gradle
plugins {
id("io.micronaut.application") version "$micronautAppVersion"
id("com.google.cloud.tools.jib") version "$googleJibVersion"

}
version = "0.1"

HazelcastClientCachingProvider is a client, it means it doesn't have any cache of its own and it can only communicate with another cache server (actually, it's recommended to use jcache as the standard Java caching API instead of provider-specific clients).
Micronaut does not automatically start a cache server by including the dependency. You're gonna have to configure it like this
Alternatively, you can configure an embedded cache directly with hibernate configuration:
hibernate:
cache:
region:
factory_class: jcache
javax:
cache:
provider: com.hazelcast.cache.impl.HazelcastServerCachingProvider
uri: <HazelcastConfig.xml>
