Play-Framework 2.3.x: 无法使用插件 "play-mailer" 发送电子邮件

Play-Framework 2.3.x: Unable to send emails using plugin "play-mailer"

我正在使用 play-framework 2.3.xscala 2.11.4。当集成 play-mailer 用于发送和来自我的应用程序的电子邮件时,没有任何反应。在日志中没有异常产生,也没有 return 值可用。以下是电子邮件属性:

smtp.host = "smtp.gmail.com" 
smtp.port = 25 
smtp.user = "n****@gmail.com" 
smtp.password = "*******"
smtp.debug = true 
smtp.mock = true 

我的 Scala 代码:

Future{
  var subject = "Invitation email";
  var from = "h****@gmail.com";
  var to = userList.map { user => user.email }.seq;
  var email: Email = new Email(subject, from, to);
  CustomUtility.sendEmail(email)
}

我需要将所有电子邮件发送到 async 任务。我的 CustomUtility 方法:

def sendEmail(email: Email){
 var message = MailerPlugin.send(email);
 println("MESSAGE >>>>>>>>>>>>>>>>>>>>>>>>>> : "+message);
}

更新

主要问题是,我没有收到电子邮件

我认为您需要根据示例代码播放邮件程序进行此更改

首先添加文件 /conf/play.plugins,内容为:

1500:play.api.libs.mailer.CommonsMailerPlugin

第二个你在application.conf中的配置必须是:

smtp.host="smtp.gmail.com"
smtp.port=465
smtp.ssl=true
smtp.tls=true
smtp.user="yourgmailuser@gmail.com"
smtp.password="yourpasswor"

控制器发送你的代码,你需要使用期货,因为我按照 github repository

中的示例
package controllers


import models.SignUpValidation
import play.api.libs.json.{JsError, Json}
import play.api.mvc._


import java.io.File

import play.api.libs.mailer._
import org.apache.commons.mail.EmailAttachment
import play.api.mvc.{Action, Controller}
import play.api.Play.current


object Application extends Controller {

  def send = Action {

val email:Email = Email(
  "Simple email",
  "Mister FROM <from@email.com>",
  Seq("Miss TO <to@email.com>"),
  attachments = Seq(
    AttachmentFile("favicon.png", new File(current.classloader.getResource("public/images/favicon.png").getPath)),
    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>")
)

val id = MailerPlugin.send(email)

Ok(s"Email $id sent!")
  }


}

您可以在 async

等异步任务中使用此代码
import play.api.libs.concurrent.Execution.Implicits.defaultContext

val futureInt: Future[Int] = scala.concurrent.Future {
  sendMail()
}

对于控制器中的异步方法

def sendWithFuture = Action.async {


      val futureString = scala.concurrent.Future {

        val email:Email = Email(
          "Simple email",
          "Mister FROM <anquegi@email.com>",
          Seq("Miss TO <antonio.querol@cuaqea.com>"),
          attachments = Seq(
            AttachmentFile("favicon.png", new File(current.classloader.getResource("public/images/favicon.png").getPath)),
            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>")
        )

        MailerPlugin.send(email)


      }
      futureString.map(i => Ok("Got result: " + i))



  }

不要忘记添加这个导入

import scala.concurrent.ExecutionContext.Implicits.global

如果您想在操作中使用 scala Futures,我建议您使用此代码

进口:

import scala.concurrent.Future
import scala.util.{Failure, Success}

方法是:

def SendUsingScalaFutures = Action {

//Your code

val userList:List[User] = List(
  new User("email1"), new User("email2"))

val task = Future {
  var subject = "Invitation email";
  var from = "anquegi@gmail.com";
  var to = userList.map { user => user.email }.seq;

  var email: Email = new Email(subject, from, to);
  CustomUtility.sendEmail(email)// this will be better to return a String

}

// whenever the task completes, execute this code
task.onComplete {
  case Success(value) => println(s"MESSAGE >>>>>>>>>>>>>>>>>>>>>>>>>> :  ${value}" )
  case Failure(e) => println(s"D'oh! The task failed: ${e.getMessage}")
}



//Other code

Ok("Finish")



 }

和您的 CustomUtility

包控制器

import play.api.libs.mailer._
import play.api.Play.current


/**
 * Created by anquegi on 13/05/15.
 */
object CustomUtility {
  def sendEmail(email: Email): Unit =  {
    val message = MailerPlugin.send(email);
    message
  }

}

和我的用户 class 只是为了示例

package models

/**
 * Created by anquegi on 13/05/15.
 */
case class User(email:String) {

}

我希望您的用户 class 和用户列表适用于您的代码,如果不能,请编写它们。我希望这有效。我总是推荐 Alvin Alexander 博客中的这个条目来使用期货:http://alvinalexander.com/scala/scala-future-semantics
