Java Smack和SASL身份验证错误-没有已知的身份验证机制

我正在尝试使用最新版本的Smack 4.1.0-beta创建一个XMPP客户端。但我在尝试登录到本地运行的OpenFire服务器时遇到错误

org.jivesoftware.smack.SmackException: SASL Authentication failed. No known authentication mechanisims.

我尝试了各种用户凭证的组合，但到目前为止没有成功。当尝试使用Pidgin或Adium连接到服务器时，al是正常的。你知道我在代码里遗漏了什么吗

XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
            .setUsernameAndPassword("admin", "admin")
            .setServiceName("localhost")
            .setHost("localhost")
            .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
            .setPort(5222)
            .build();

    AbstractXMPPConnection connection = new XMPPTCPConnection(config);

    try {

        connection.connect();

        connection.login();

        connection.disconnect();

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

尝试使用主机/servicename的ip地址

我错误地导入了错误的依赖项。在签出文档（）时，使用Gradle导入正确的依赖项解决了问题

compile("org.igniterealtime.smack:smack-java7:4.1.0-beta1")
compile("org.igniterealtime.smack:smack-tcp:4.1.0-beta1")
compile("org.igniterealtime.smack:smack-extensions:4.1.0-beta1")

这是完整的解决方案，请仔细查看

效验如神u r Xmpp Super Hero:DThanks@KhalidElSayed，我最近更新了答案，如果您使用的是更新版本的

smack

，即4.2.0-beta2，请使用它谢谢@gopalinghsirvi更新的答案，u r awesome:）设置数据包回复超时。这不是一个好主意。当移动到另一台服务器时，IP可能会发生变化，您必须更新商店中发布的应用程序。这需要时间，不是一个好主意。

XMPPTCPConnectionConfiguration.Builder builder = XMPPTCPConnectionConfiguration.builder();
builder.setHost("example.com");
