Will Spring Session persist Web Flow state?

Question

I have a couple of wizards that seem like a good fit for Spring Web Flow, but Web Flow stores significant flow state server-side, and I'm not sure where. I'm using a rapid integration and deployment cycle, so durability across server restarts is a must.

I think that Web Flow uses the SessionBindingConversationManager to store flow state in the HttpSession, and so Spring Session will persist that state into the external session store. Is this correct? If so, do I need to do anything besides configuring Spring Session and adding the Web Flow components to my application?

Answer 1

By default, Web Flow stores conversation state in the HttpSession in the webflowConversationContainer attribute. Spring Session will persist this to an external store, and servers sharing the session repository will have synchronized state for flows.
