[gatewaysessioninactiveevent event] 1 Connect your own client disconnect

1. Must be in their own process to listen to

2.GatewayRouteHandler Of channelInactive The central supervisor heard that his client was disconnected , Will throw an asynchronous event in it

    @Override
    public void channelInactive(ChannelHandlerContext ctx) throws Exception {
        var session = SessionUtils.getSession(ctx);
        if (session == null) {
            return;
        }

        var sid = session.getSid();
        var uid = (Long) session.getAttribute(AttributeType.UID);
        //  Asynchronous events 
        EventBus.asyncSubmit(GatewaySessionInactiveEvent.valueOf(sid, uid == null ? 0 : uid.longValue()));

        super.channelInactive(ctx);
    }

3. stay GatewayController.java Just listen to the event and handle it

@Component
public class GatewayController {

    @EventReceiver
    public void onGatewaySessionInactiveEvent(GatewaySessionInactiveEvent event) {
        var sid = event.getSid();
        var uid = event.getUid();

        //  If the player is not logged in , You don't do anything 
        if (uid <= 0) {
            return;
        }

        //  Listen for client disconnect 
        var packet = LogoutRequest.valueOf();

        var loadBalancer = NetContext.getConfigManager().consumerLoadBalancer();

        //  This is consumer Connected to provider, therefore ： Yes, it can be found consumer And provider Connection between session Of .  Tell directly through this 
        var consumerSession = loadBalancer.loadBalancer(packet, uid);

        //  Player logout 
        var gatewayAttachment = new GatewayAttachment(sid, uid);
        // true:  The client is disconnected 
        gatewayAttachment.setClient(true);

        // rpc Tell all servers , This person dropped the line 
        NetContext.getRouter().send(consumerSession, packet, gatewayAttachment);
    }

}

4. stay gateway Of application.xml Multiple consumers are configured in

  <net:consumer load-balancer="consistent-hash">
            <net:module name="tankHome"/>
            <net:module name="tankCache"/>
        </net:consumer>

It should be telling them LoginOut Player client for

5. stay home Of LoginController There's monitoring

    @PacketReceiver
    public void atLogoutRequest(Session session, LogoutRequest request, GatewayAttachment gatewayAttachment) {
        logger.info("c[{}][{}] Players quit the game ", gatewayAttachment.getUid(), gatewayAttachment.getSid());

        var uid = gatewayAttachment.getUid();
        var player = playerEntityCaches.load(uid);
        player.sid = 0;
        player.session = null;
        playerEntityCaches.update(player);
    }
