Code:

    @EventListener
    public void handleWebSocketDisconnectListener(SessionDisconnectEvent event) {
        StompHeaderAccessor headerAccessor = StompHeaderAccessor.wrap(event.getMessage());
        log.debug("Disconnect socket " + event.getUser().getName());
        Map<String, Object> sessionAttributes = headerAccessor.getSessionAttributes();
        Runnable leaveMsg = (Runnable) sessionAttributes.get(LEAVE_MSG_KEY);
        leaveMsg.run();
    }
