即使使用应用程序密码，使用 Google smtp 服务器时用户名和密码也未被接受错误

Question

我正在尝试配置我的 Spring Boot 应用程序以使用 Google SMTP 服务器发送通知。我已经为我的应用程序生成了应用程序密码，但在尝试从我的应用程序内发送消息时，我一直使用相同的错误。我做错了什么？

这是应用程序 yaml（我用占位符替换了实际的用户名和密码：

mail:
    host: smtp.gmail.com
    port: 587
    username: <username>
    password: <app-password>
    properties:
      mail:
        smtp:
          auth: true
          starttls:
            enable: true
        debug: true

这是控制台输出：

我试过几次设置应用程序密码，但都是徒劳的

我刚刚解决了这个问题！问题是我的用户名实际上是另一个邮件服务，即使我将它用作我的谷歌帐户的登录名，但由于这个事实它没有用。
