更改databricks中的scala代码以基于电子邮件发送分组数据

import org.apache.spark.sql.SparkSession

// 创建 Spark 会话
val spark = SparkSession.builder.appName("Email Grouped Data").getOrCreate()

// 示例数据
val data = Seq(
  ("alice@example.com", "Sales", 100),
  ("bob@example.com", "Sales", 150),
  ("alice@example.com", "Marketing", 200),
  ("bob@example.com", "Marketing", 250)
)

val df = spark.createDataFrame(data).toDF("email", "department", "amount")

// 分组数据
val groupedData = df.groupBy("email", "department")
  .agg(sum("amount").alias("total_amount"))

// 将分组数据转换为字符串
val groupedDataString = groupedData.collect().map(row => s"${row.getString(0)} - ${row.getString(1)}: ${row.getDouble(2)}").mkString("\n")

// 发送电子邮件的函数
def sendEmail(to: String, subject: String, body: String): Unit = {
  val props = new Properties()
  props.put("mail.smtp.host", "smtp.example.com") // 替换为您的 SMTP 服务器
  props.put("mail.smtp.port", "587") // 替换为您的 SMTP 端口
  props.put("mail.smtp.auth", "true")
  props.put("mail.smtp.starttls.enable", "true")

  val session = Session.getInstance(props, new Authenticator {
    override def getPasswordAuthentication: PasswordAuthentication = {
      new PasswordAuthentication("your_email@example.com", "your_password") // 替换为您的电子邮件和密码
    }
  })

  try {
    val message = new MimeMessage(session)
    message.setFrom(new InternetAddress("your_email@example.com")) // 替换为您的电子邮件
    message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to): _*)
    message.setSubject(subject)
    message.setText(body)

    Transport.send(message)
    println("邮件发送成功")
  } catch {
    case e: Exception => e.printStackTrace()
  }
}

// 发送电子邮件
sendEmail("recipient@example.com", "Grouped Data", groupedDataString) // 替换为收件人的电子邮件
