Class FixedDurationExpirationSessionRepository<S extends org.springframework.session.Session>

java.lang.Object
org.springframework.session.data.gemfire.expiration.repository.FixedDurationExpirationSessionRepository<S>
All Implemented Interfaces:
org.springframework.session.SessionRepository<S>
public class FixedDurationExpirationSessionRepository<S extends org.springframework.session.Session> extends Object implements org.springframework.session.SessionRepository<S>
The FixedDurationExpirationSessionRepository class is a SessionRepository implementation wrapping an existing SessionRepository, data store specific, implementation in order to implement a fixed Duration expiration policy on the Session. That is, the Session will always expire (or be considered "expired") after a fixed amount of time. Even if the user Session is still actively being accessed up to the last moment right before the Session is about to expire, the Session will expire regardless. This may be useful in certain UCs where, for security reasons, the Session must expire no matter what.
Since:
2.1.0
