我正在使用以下类发送邮件，但作为回应我得到了一些例外，我已粘贴在这里。用户名和密码是否正确，可能是错误的原因是什么？

您的Google帐户设置不允许通过gmail或google以外的其他外部应用程序连接到该帐户。您的凭据没问题，但是您的应用程序似乎不那么安全了。请参阅链接https://support.google.com/accounts/answer/6010255?hl=en

而不是调用Transport.send
你可以尝试
transport = session.getTransport("smtp");
transport.connect(host, username, pass);
并检查连接呼叫的结果。如果成功，请继续
transport.sendMessage(message, message.getAllRecipients())
另一方面，你可以将它添加到你的道具
properties.put("mail.smtp.starttls.enable", "true")
