public interface SessionKeyA
SessionKeyis a key that allows look-up of any particular
Sessioninstance. This is not to be confused what is probably better recognized as a session attribute key - a key that is used to acquire a session attribute via the
SessionKeylooks up a Session object directly. While a
SessionKeyallows lookup of any Session that might exist, this is not something in practice done too often by most Shiro end-users. Instead, it is usually more convenient to acquire the currently executing
Subject's session via the
Subject.getSession()method. This interface and its usages are best suited for framework development.
getSessionIdReturns the id of the session to acquire. Acquiring sessions by ID only is a suitable strategy when sessions are natively managed by Shiro directly. For example, the Servlet specification does not have an API that allows session acquisition by session ID, so the session ID alone is not sufficient for ServletContainer-based SessionManager implementations.
- the id of the session to acquire.
