我已经学习了一系列教程，并提出了一个非常简单和简约的Java应用程序，它应该连接到谷歌对话并允许我向帐户发送消息。
我已关闭SASLAuth安全设置以使示例正常工作，但是当我尝试连接到Google服务器时，我收到了一个复杂的TLS错误，我认为我被迫启用SASLAuth安全设置。但是，如果我启用它们，我又会出现另一个错误。这是我正在使用的非常简单的代码示例。我错过了什么？

xmppManager.printRoster();
boolean isRunning = true;
while (isRunning) {
Thread.sleep(50);
}
xmppManager.destroy();
}
}
我认为错误与这两个代码行有关：
config.setSASLAuthenticationEnabled(false);
config.setSecurityMode(SecurityMode.disabled);
但如果是，那我就不知道如何正确配置它们了！
禁用SASLAuth时出错：

用
更改两行config.setSASLAuthenticationEnabled(true);
config.setSecurityMode(ConnectionConfiguration.SecurityMode.enabled);

您需要在Google帐户中启用“访问安全性较低的应用”，以便进行简单的用户名/密码登录。或者您需要使用用户ID和访问令牌实现OAUTH2身份验证。
