【问题讨论】：

AuthenticationException，查看本地/cloudbees之间的差异，非本地身份验证会失败的任何原因？
我猜它无法验证您提供的凭据。你确定你使用的是正确的主机服务器
我得到了相同的代码。与我的电子邮件相同的用户凭据。我只是不知道为什么它不在非本地发送。
顺便说一句，我正在使用 spring 4
Afaik，Google 必须允许您的应用程序使用您自己的帐户：转到 accounts.google.com/DisplayUnlockCaptcha 并且在几分钟内 google 应该能够记住应用程序/服务并允许您的应用程序访问您的帐户（请参阅此处email.about.com/od/gmailtips/qt/…) 但是，更简单的方法是使用基于云的电子邮件基础架构和发送服务，例如 SendGrid。在 cloudbees，您可以找到几个有关如何使用它的示例（即 github.com/CloudBees-community/tomcat7-sendgrid-clickstart）

【解决方案1】：

默认情况下，Gmail 帐户是高度安全的。当我们从非 gmail 工具使用 gmail smtp 时，电子邮件被阻止。要在我们的本地环境中进行测试，请降低您的 gmail 帐户的安全性，因为

登录到 Gmail。
以https://www.google.com/settings/security/lesssecureapps访问网址
选择“开启”
