Method Detail

onStart

void onStart(Session session)
Notification callback that occurs when the corresponding Session has started.

Parameters:
session - the session that has started.

onStop

void onStop(Session session)
Notification callback that occurs when the corresponding Session has stopped, either programmatically via Session.stop() or automatically upon a subject logging out.

Parameters:
session - the session that has stopped.

onExpiration

void onExpiration(Session session)
Notification callback that occurs when the corresponding Session has expired.

Note: this method is almost never called at the exact instant that the Session expires. Almost all session management systems, including Shiro's implementations, lazily validate sessions - either when they are accessed or during a regular validation interval. It would be too resource intensive to monitor every single session instance to know the exact instant it expires.

If you need to perform time-based logic when a session expires, it is best to write it based on the session's lastAccessTime and not the time when this method is called.

Parameters:
session - the session that has expired.
