Spring Session with hazelcast session events firing

Question

I am using Spring Session with Hazelcast and Spring Websockets. As I don't need clustarization I use hazelcast with MapSessionRepository. But it doesn't fire event on session expiring or session deleting. What I want is to listen to SessionExpiredEvent and then disconnect user via websocket immediately. So I have two problems:

1. MapSessionRepository does not firing needed events (SessionExpiredEvent and etc.)

2. I don't realize how to send websocket notification using expired http session. I need something like simpMessageTemplate.convertAndSendToUser(). But how I can get the user?

So the only one variant I can see is to write own implementation for SessionRepository<ExpiringSession> with events firing. I hope you understood my question. Thanks in advance.

Spring Session Hazelcast support does provide publishing of session events. The functionality itself is implemented using SessionEntryListener so make sure you use @EnableHazelcastHttpSession annotation which configures all the necessary components for Hazelcast integration.

It might also be of your interest that the upcoming Spring Session 1.3 (currently at 1.3.0.M2) will provide first-class Hazelcast support with new HazelcastSessionRepository (which will, among other things, replace SessionEntryListener).
