Xmpp Openfire：将联系人订阅状态设置为'；从'；而不是'；两者'；

嗨，我正面临一个关于openfire和smack的问题。我有一个使用smack和openfire开发的jabber机器人。 当任何用户添加bot时，都有他/她的联系人，然后在整个过程结束时，ofRoster（openfire）表的订阅状态设置为“from”。 这一过程的预期结果是“两者皆有”

这是我处理新添加连接的代码

xmppConnection.getConnection().getRoster().setSubscriptionMode(Roster.SubscriptionMode.manual);
xmppConnection.getConnection().addPacketListener(
    new PacketListener() {
        @Override
        public void processPacket(Packet paramPacket) {
            System.out.println("\n\n");

            if(paramPacket instanceof Presence){
                Presence presence = (Presence)paramPacket;
                String email = getEmailIdFromJabberId(presence.getFrom());
                System.out.println("chat invite status changed by user: : " + email + " calling listner");
                //if(presence.getType().equals(Presence.Type.subscribed) || presence.getType().equals(Presence.Type.subscribe) ){
                System.out.println("presence: " + presence.getFrom() + "; type: " + presence.getType() + "; to: " + presence.getTo() + "; " + presence.toXML());
                Roster roster = xmppConnection.getConnection().getRoster();
                for(RosterEntry rosterEntry : roster.getEntries()){
                    System.out.println("jid: " + rosterEntry.getUser() + "; type: " + rosterEntry.getType() + "; status: " + rosterEntry.getStatus());
                }
                System.out.println("\n\n\n");

                if( presence.getType().equals(Presence.Type.subscribe) ){
                    //chatInviteAcceptanceListner.onChatInviteAccept(email);

                    Presence newp = new Presence(Presence.Type.subscribed);
                    newp.setMode(Presence.Mode.available);
                    newp.setPriority(24);
                    newp.setTo(presence.getFrom());
                    //presence.addExtension(new AvatarBroadcastExtension(imageHash));
                    xmppConnection.getConnection().sendPacket(newp);
                } else if(presence.getType().equals(Presence.Type.unsubscribe)){
                    //chatInviteAcceptanceListner.onChatInviteReject(email);
                    Presence newp = new Presence(Presence.Type.unsubscribed);
                    newp.setMode(Presence.Mode.available);
                    newp.setPriority(24);
                    newp.setTo(presence.getFrom());
                    //presence.addExtension(new AvatarBroadcastExtension(imageHash));
                    xmppConnection.getConnection().sendPacket(newp);
                }
            }


        }
    }, 
    new PacketFilter(){
        public boolean accept(Packet packet) {

            if(packet instanceof Presence){
                Presence presence = (Presence)packet; 
                if(presence.getType().equals(Presence.Type.subscribed) 
                        || presence.getType().equals(Presence.Type.subscribe)
                        || presence.getType().equals(Presence.Type.unsubscribed) 
                        || presence.getType().equals(Presence.Type.unsubscribe) ){
                    //System.out.println("packet: " + packet);
                    return true;
                }
            } 
            return false;
        }
    });

我们可以在花名册中添加联系人而不在xmpp中发送和接收订阅请求吗？我使用github代码

    <presence to="testdoctor@answers.exampledomain.com" from="testuser2@answers.exampledomain.com" type="subscribe"></presence>
<iq id="612-4980" to="testdoctor@answers.exampledomain.com/smoke" type="set"><query xmlns="jabber:iq:roster"><item jid="testuser2@answers.exampledomain.com" subscription="from"></item></query></iq>
