Hi,
As Hugi wrote, you can access the list via the session store.
Be careful with access to objects inside those sessions, especially EOs since
you are outside their normal RR loop request.
I have a standard way to list active users and keep track of last access inside
session by adding those attributes:
private long lastSleepDate;
private long lastUserRequestDate;
private boolean isRequestFromUser;
and adding those overrides...
@Override
public void awake() {
super.awake();
....
isRequestFromUser = true;
}
@Override
public void sleep() {
lastSleepDate = System.currentTimeMillis();
if (isRequestFromUser) {
lastUserRequestDate = lastSleepDate;
}
super.sleep();
}
public void setRequestIsPing() {
isRequestFromUser = false;
}
The setRequestIsPing is to discriminate auto refresh ping request in my page
wrapper use to keep session alive when the app is displayed. I have this in the
template:
<wo:AjaxPing frequency = "100000"><wo:string value =
"$pingString"/></wo:AjaxPing>
And this in the component java class:
public String pingString() {
if (ERXApplication.isAjaxRequest(context().request())) {
session().setRequestIsPing();
}
return null;
}
And this to list active sessions (SessionInfo is POJO):
WOServerSessionStore sessionStore = (WOServerSessionStore)
WOApplication.application().sessionStore();
@SuppressWarnings("unchecked")
NSArray<Session> sessions =
sessionStore._sessions().allValues();
NSMutableArray<SessionInfo> sessionInfos = new
NSMutableArray<>();
for (Session session : sessions) {
SessionInfo info = new SessionInfo();
info.hashCode = session.hashCode();
info.lastSleepDatetime = session.lastSleepDatetime();
info.lastUserRequestDate =
session.lastUserRequestDate();
info.timeOut = session.timeOutMillis();
info.usager = session.userAccessService().currentUser();
sessionInfos.add(info);
}
new
ERXKey<LocalDateTime>("lastUserRequestDate").desc().sort(sessionInfos);
Regards,
Samuel
