Hazelcast Spring Cache - SimpleKey serialization

[miloss....@gmail.com]

Hello.

We are using Hazelcast as Spring cache manager in client-server configuration. For some methods where parameters are more complex Spring uses this class: org.springframework.cache.interceptor.SimpleKey

It naturally leads to exception:  com.hazelcast.nio.serialization.HazelcastSerializationException: java.lang.ClassNotFoundException: org.springframework.cache.interceptor.SimpleKey

I would like to ask what is the best approach in this scenario. Is there better solution apart from extending server image with whole Spring core ?

Thank you for your response.

Best regards,

Milos.

Hi Miloss,

I haven't seen this error before. 

I suggest you to create a GitHub issue with a reproducer. You are definitely right that server classpath should not include Spring Core Classes.

I ended up using custom KeyGenerator. Now it works.
