This is done on purpose, to adhere to the WebSessionStore
contract. WebSessionStore
implementations aren't all supposed to give you a way to list all persisted sessions (especially if storage is distributed).
If you want to batch remove sessions, you can do the following:
Set<String> sessionIds = this.store.getSessions().keySet();
Flux.fromIterable(sessionIds)
.flatMap(sessionId -> this.store.removeSession(sessionId))
.blockLast();
If you'd like to selectively invalidate sessions, you can do this:
Set<String> sessionIds = this.store.getSessions().keySet();
Flux.fromIterable(sessionIds)
.filter(sessionId -> ...) // filter sessions based on your criteria?
.flatMap(sessionId -> this.store.retrieveSession(sessionId))
.map(webSession -> webSession.invalidate())
.blockLast();
Note: I used a blocking operator in this code snippet, but you shouldn't block in the middle of a reactive pipeline and should probably use .then()
and connect this to the rest of your pipeline.
For more questions, please use StackOverflow. Thanks!

I understand whether the efficiency of removing a session through traversal is too low. This type of storage is mainly aimed at standalone applications rather than distributed applications, so can the issue of distribution be ignored. Returning Session as ConcurrentHashMap facilitates efficient execution of clearing functions. thanks
