Vaadin 7 Session Id

Question

Does Vaadin 7 offer some kind of session identifier? I want to track some usage by each session.

I looked at the doc for VaadinSession but did not notice any.

I suppose I could roll my own by generating a UUID and attaching it to the VaadinSession with a call to setAttribute . But no need if Vaadin gives me an identifier.

Answer 1

您可以通过VaadinSession （然后是WrappedSession ）获取SESSION_ID 。

VaadinSession.getCurrent().getSession().getId()
