Smack"必须有本地(用户)JID设置"错误

Question

无法理解为什么会出现此错误并且应用程序崩溃.

低于错误:

我试图解决使用以下url中给出的解决方案,但它也不适用于我的情况.Url是: - https://community.igniterealtime.org/thread/58150

代码用于连接到ejabberd并使用Smack 4.1登录: -

XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration.builder();
    config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
    config.setServiceName(Constants.HOST);
    config.setPort(Constants.PORT);
    config.setHost(Constants.HOST);
    config.setDebuggerEnabled(true);
    config.setSendPresence(true);
    config.setUsernameAndPassword(strUsername + "@" + Constants.HOST, strPassword);


    SASLAuthentication.blacklistSASLMechanism("SCRAM-SHA-1");
    SASLAuthentication.blacklistSASLMechanism("DIGEST-MD5");
    SASLAuthentication.unBlacklistSASLMechanism("PLAIN");
    objXmpptcpConnection = new XMPPTCPConnection(config.build());
    objXmpptcpConnection.setUseStreamManagement(true);
    objXmpptcpConnection.setUseStreamManagementResumption(true);
    try {
        objXmpptcpConnection.connect();
        System.out.println("Connected to===>" + objXmpptcpConnection.getHost());
        objXmpptcpConnection.login();

    } catch (XMPPException e) {
        e.printStackTrace();

    } catch (SmackException e) {
        e.printStackTrace();

    } catch (IOException e) {
        e.printStackTrace();

    }

实际错误发生在下面的函数中,它返回了我正在聊天的用户的最后状态: -

   public String getLastActivity(XMPPTCPConnection objXmpptcpConnection, String strUser) {

        try {
            LastActivityManager objLastActivityManager = LastActivityManager.getInstanceFor(objXmpptcpConnection);
            LastActivity objLastActivity = null;
            $$ objLastActivity = objLastActivityManager.getLastActivity(strUser + "@" + Constants.HOST);
            System.out.println("MESSAGE:" + objLastActivity.getStatusMessage());
            System.out.println("IDLE TIME::" + objLastActivity.getIdleTime());

            return convertTime(objLastActivity.getIdleTime());

        } catch (SmackException.NoResponseException e) {
            e.printStackTrace();
            return "Offline";
        } catch (XMPPException.XMPPErrorException e) {
            e.printStackTrace();
            return "Offline";
        } catch (SmackException.NotConnectedException e) {
            e.printStackTrace();
            return "Offline";
        }

    }

我用符号标记了错误行$$

用户名错误：

您正在尝试与 user@server@server 连接。不要连接 Jid 部分，它是自动的。

此外，您必须指定用户的RESOURCE（例如，设备的名称，默认为Spark）。

注意：desktop smack 可能会针对 android 使用不同的类。也许您在身份验证方面还有其他问题，但指定错误的 JID 可以让您“连接”但不能“登录”，并且忽略资源会破坏某些功能。
