Question

下面，我粘贴了我的代码，用于发送带附件的邮件。我没有忘记我的代码，但我在我的网络应用程序中得到NoSuchElementException。任何人都可以告诉我缺少什么或服务器部分有问题吗？我是否必须在代码项目中添加apache或任何服务器许可证。

以下是我的代码：

val email = Email(
  "Simple email",
  "Mister FROM <vignesh.gopal@hubino.com>",
  Seq("Miss TO <ibrahim.sultan@hubino.com>"),
  attachments = Seq(
    AttachmentFile("leak.txt", new File("E:/oui_mem_leak.txt")),
    AttachmentData("data.txt", "data".getBytes, "text/plain", Some("Simple data"), Some(EmailAttachment.INLINE))), 
  bodyText = Some("A text message"),
  bodyHtml = Some("<html><body><p>An <b>html</b> message</p></body></html>")
)
println("email contents: " + email)
MailerPlugin.send(email)

application.conf

smtp.host  = localhost
smtp.port  = 9000
smtp.ssl   = false
smtp.tls   = false
smtp.debug = false
smtp.mock  = false

build.sbt

  "org.apache.commons" % "commons-email" % "1.3.3",
  "com.typesafe.play" %% "play-mailer" % "2.4.1"

例外：

Answer 1

看起来配置错误。你配置了

Geolocate (with page caching support)

在你的conf / play.plugins？

Answer 2

这一切都发生了，因为我们使用的是插件的过时版本。见@ Bhavya的评论

该插件的最新版本位于：https://github.com/playframework/play-mailer

发送电子邮件时Play Framework中的NoSuchElementException？
