发送电子邮件jsp Glassfish

标签： java jsp glassfish ejb javamail

我要做的是在特定时间内通过Gmail自动向客户发送电子邮件作为提醒。所以我在YouTube上找到了一个教程：https://www.youtube.com/watch?v=gy2eEZhLihk，我做了同样的事情，相同的代码，但我没有工作。

这是我的代码，我正在使用eclipse和Glassfish服务器。

 Transport transport = mailSession.getTransport("smtps");// change smtp to smtps

并禁用您的PC防病毒和防火墙，然后尝试

并启用“访问不太安全的应用”

https://www.google.com/settings/security/lesssecureapps

然后就能成功发送邮件。
