【问题描述】：

我正在尝试在 Play 中发送电子邮件！框架 v 2.1.1。

在 build.scala 我有：

"com.typesafe" %% "play-plugins-mailer" % "2.1.0"

在 conf/application.conf 我有：

smtp.host=smtp.gmail.com
smtp.port= "587"
smtp.ssl=true
smtp.tls=true
smtp.user="dylanrboudro@gmail.com"
smtp.password="xxxxxx"

我也试过 smtp.port = "465"

发送邮件的方法是：

 public void Email() {

    MailerAPI mail = play.Play.application().plugin(MailerPlugin.class).email();
    mail.setSubject("test");
    mail.addRecipient("dylanrboudro@gmail.com");
    mail.addFrom("DevOpsNotifications@gmail.com");
    String body = "this is the first email sent by the devops requestor";
    mail.sendHtml(body);

我收到此错误：

[RuntimeException: org.apache.commons.mail.EmailException: Sending the email to the following server failed : smtp.gmail.com:587]

还有这个堆栈跟踪：

有人知道吗？非常感谢！

【问题讨论】：

我在连续几次调用 Mailer 时遇到了这个异常。也许这是为了防止垃圾邮件的某种超时！？

【解决方案1】：

您需要从 smtp.port 设置中删除引号。
应该是smtp.port = 587。
我没有在 smtp.password 字段中使用引号，它对我有用。

【讨论】：

您的密码中似乎没有使用 $ 等特殊字符。如果您使用它们，则不可避免地要用双引号将您的密码括起来。

【解决方案2】：

这是一个示例应用程序，可以满足您的需要： https://github.com/jamesward/play-emailer

也许试试那个应用程序，看看它是否有效。如果不是，那么您的问题很可能是您的网络不允许出站连接。
