I am creating the session using
HttpSession session = request.getSession();
Before creating session I want to check if it exists or not. How would I do this?

See Question&Answers more detail:osIf you want to check this before creating, then do so:
HttpSession session = request.getSession(false);
if (session == null) {
// Not created yet. Now do so yourself.
session = request.getSession();
} else {
// Already created.
}
If you don't care about checking this after creating, then you can also do so:
HttpSession session = request.getSession();
if (session.isNew()) {
// Freshly created.
} else {
// Already created.
}
That saves a line and a boolean
. The request.getSession()
does the same as request.getSession(true)
.
