我正在尝试从App Server(TOMCAT)创建多用户聊天组,我在servlet中创建了一个XMPP bot。

根据我的要求,我必须从App服务器创建一个多用户聊天组(在app服务器上使用xmpp bot),并从android app加入用户。

创建多用户聊天组并从Android加入用户(使用aSmack)工作正常,当我尝试在appServer(TOMCAT)上做同样的事情时,我收到错误,

首先,当我尝试创建MUC时,我得到“无法创建一个带有Android的思科库的多用户聊天(MUC)房间:”packet.DefaultPacketExtension无法转换为packet.MUCUser“,

当我搜索SO时,我找到了POST,其中@FLOW提到了这个错误的共鸣

  

org.jivesoftware.smack.packet.DefaultPacketExtension无法转换为   org.jivesoftware.smackx.packet.MUCUser通常是一个指标   你没有初始化aSmack的静态代码   为各种数据包(和数据包)注册Smack提供程序   扩展)Smack类。   对于大多数aSmack版本,只需调用

即可      

SmackAndroid.init(Context ctx)

     

会做到这一点。

在Smack核心软件包中没有这样的方法,它负责为Smack的各种数据包(和数据包扩展)类注册Smack提供程序。

所以我在这个link

上使用configure(ProviderManager pm)方法手动配置提供

现在配置提供程序后,一切都应该正常,但我仍然无法创建MUC组

我的代码如下

    SmackConfiguration.setPacketReplyTimeout(packetReplyTimeout);

    if(service != null)
        config = new ConnectionConfiguration(server, port, service);
    else
        config = new ConnectionConfiguration(server, port);

    config.setSASLAuthenticationEnabled(true);
    config.setSecurityMode(SecurityMode.disabled);
    config.setDebuggerEnabled(true);
    connection = new XMPPConnection(config);
    connection.connect();

    System.out.println("Connected: " + connection.isConnected());
    chatManager = connection.getChatManager();
    messageListener = new MyMessageListener();

if (connection!=null && connection.isConnected()) {
        configure(ProviderManager.getInstance());
        connection.login(username, password);
    }
   MultiUserChat muc = new MultiUserChat(connection, "1234567@conference.localhost");

        muc.create("Jonny");

          Form form = muc.getConfigurationForm();
             Form submitForm = form.createAnswerForm();

            for (Iterator<FormField> fields = form.getFields(); fields.hasNext();) {
                FormField field = (FormField) fields.next();  
                if (!FormField.TYPE_HIDDEN.equals(field.getType())
                        && field.getVariable() != null) {
                   // show("field: " + field.getVariable());
                    // Sets the default value as the answer
                    submitForm.setDefaultAnswer(field.getVariable());
                }
            }

            List<String> owners = new ArrayList<String>();

            owners.add(xmppManager.getXmppConnection().getUser());
            submitForm.setAnswer("muc#roomconfig_roomowners", owners);
            //submitForm.setAnswer("muc#roomconfig_roomname", );
            submitForm.setAnswer("muc#roomconfig_persistentroom", true);
            muc.sendConfigurationForm(submitForm);
            muc.join(MucNick);
            muc.sendMessage("hello everybody");
            muc.addMessageListener(
                    new PacketListener() {
                        @Override
                        public void processPacket(Packet packet) {
                                message = (Message) packet;
                            if (message.getBody() != null) {
                                String fromName = StringUtils.parseBareAddress(message
                                        .getFrom());
                                System.out.println("andro xmpp client"+ "Text Recieved--" + message.getBody()
                                        + " from " + fromName );
                                //messages.add(fromName + ":");
                                //messages.add(message.getBody());
                                //infobox.append("message arrieved "+" from::"+message.getFrom()+"__"+message.getBody());

                                // Add the incoming message to the list view
                                //Log.i("andro xmpp client","group messages__"+ messages.toString());

                            }
                        }
                    }

                    );

1 个答案:

答案 0 :(得分:1)

  

在核心Smack包中没有这样的方法来处理   为各种数据包(和数据包)注册Smack提供程序   扩展)Smack的类。

是的(虽然没有在smack-core中)。

  

所以我手动配置使用configure(ProviderManager)   pm)此链接上的方法

从不手动配置提供商(至少不是,如果您不知道自己在做什么)。

  

线程中的异常“Smack Packet Reader(0)”   java.lang.NoSuchMethodError:   org.jivesoftware.smack.util.StringUtils.parseDate(Ljava /郎/字符串;)Ljava / util的/日期;       在org.jivesoftware.smackx.provider.DelayInformationProvider.parseExtension(DelayInformationProvider.java:45)

您看到的是NoSuchmethodError。出于某种原因,StringUtils中的parseDate方法不存在DelayInformationProvider除外。难道你是在混合不同主要版本的Smack组件吗?您使用哪个Smack版本?
