Hazelcast session updates - Spring Boot

[bakedzebra]

Hi,

Could you please help me to clarify something: I've noticed that all Sessions that are retrieved from HazelcastSessionRepository are the copies of basic sessions that stored in MapProxyImpl instance. So if I change a proxy session's attribute property: (This example is not an actual usage, Its just for clarification)

List list = hazelcastRepository.getSession("1").getAttribute("List");
list.add(new Object()); //list.size = 1

List list1 = hazelcastRepository.getSession("1").getAttribute("List");
list1.size() // 0

The basic session's (in MapProxyImpl) attribute 'List' is not updated as well.

Is there a way to merge original session object inside MapProxyImpl and the proxy (copy) session attributes or enable direct session access, not via proxy?

I know, that I could use HazelcastSessionRepository.save() - but the HazelcastSessionRepository.Session has unreachable access.

Thanks!

I think it is because org.springframework.session.hazelcast.HazelcastIndexedSessionRepository#save will not take a branch if (!session.delta.isEmpty()) {... because it does not go reflectively through all session data, but it relies on delta field management in org.springframework.session.hazelcast.HazelcastIndexedSessionRepository.HazelcastSession#setAttribute. It means you should get the list, clone it, add a field to the clone and setAttribute(list).

I expect other session repositories to work in the same way.
