In my application, I have an admin that can delete users. so when I delete a user from the admin session I want that the deleted user should get logged out automatically.
I know the user's session id whom I delete but I don't know how to invalidate a session using the session id.
I would like something like: invalidate(SessionId);
Is it possible in any way? I think it is possible using a filter and checking the database every on request but is there another way where I don't need check the db on every httprequest?
Thanks. :D
I think I see a solution using the Spring Security infrastructure, with the SessionRegistry class.
You have to register the HttpSessionEventPublisher
in the web.xml
:
<listener>
<listener-class>org.springframework.security.web.session.HttpSessionEventPublisher</listener-class>
</listener>
In your Spring config, declare the SessionRegistry.
<bean id="sessionRegistry"
class="org.springframework.security.core.session.SessionRegistryImpl" />
In your administration console, you have to use the SessionRegistry
to retrieve the SessionInformation
of the user and call expireNow
. At the next request of the user, a servlet filter should make the HttpSession expire. The javadoc of SessionInformation has some explanation about how it works.
Let us know if that helps.
// to end a session of a user:
List<SessionInformation> sessions = sessionRegistryImpl.getAllSessions(user, false);
sessionRegistryImpl.getSessionInformation(sessions.get(0).getSessionId()).expireNow();
// note: you can get all users and their corresponding session Ids:
List<Object> users = sessionRegistryImpl.getAllPrincipals();
List<String> sessionIds = new ArrayList<>(users.size());
for (Object user: users) {
List<SessionInformation> sessions = sessionRegistryImpl.getAllSessions(user, false);
sessionIds.add(sessions.get(0).getSessionId());
}
Along with what has been suggested by @LaurentG, following needs to be added in your spring config file :
<session-management>
<concurrency-control session-registry-alias="sessionRegistry" />
</session-management>
for it to work. Also @zygimantus answer can be used for accessing the session data.
