scala - javax.mail.AuthenticationFailedException

Question

我的目标是通过电子邮件发送数据帧。下面是我的代码：

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>
<div class="dash-menu">
	<h2>Hi , Welcome back</h2>
<div class="dash-header">
<ul>
<li>Menu1</li>
<li>Menu2</li>
<li>Menu3</li>
<li><i class="fa fa-bars" aria-hidden="true"></i></li>
</ul>
<img src="">
</div><!--dash-header-->
</div><!--dash-menu-->

但是当我执行代码时，我得到以下错误：

  

线程中的异常＆＃34; main＆＃34; javax.mail.AuthenticationFailedException

我在这里缺少什么。

Answer 1

摆脱身份验证器（根本没有使用）和mail.smtp.user，mail.smtp.password和mail.smtp.auth属性，然后调用Transport.send method that takes a user name and password 。如果仍然无效，请发布JavaMail debug output。

Answer 2

我需要将身份验证传递给会话，这是我错过的，下面的代码对我有用：

val sparkConf = new SparkConf().setAppName("E-mail Alert").setMaster("local")
val sc = new SparkContext(sparkConf)
var bodyText = "Test mail"
val username = "*****************"
val password = "************************"
val smtpHost = "email-smtp.us-east-1.amazonaws.com"

// Set up the mail object
val properties = System.getProperties
properties.put("mail.smtp.host", smtpHost)
properties.put("mail.smtp.user", username);
properties.put("mail.smtp.password", password);
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.port", "587")
properties.put("mail.smtp.starttls.enable", "true");

val auth:Authenticator = new Authenticator() {
  override def getPasswordAuthentication = new
      PasswordAuthentication(username, password)
}

val session = Session.getInstance(properties,auth)
val message = new MimeMessage(session)

// Set the from, to, subject, body text
message.setFrom(new InternetAddress("no-reply@*****.com"))
message.setRecipients(Message.RecipientType.TO, "ajayv@****.com")
message.setSubject("Count of DeviceIDs we are sent daily")
message.setText(bodyText)

// And send it
Transport.send(message)
