使用javax.mail發送消息

我想使用javax.mail從[email protected]發送郵件到[email protected]。我已經嘗試了下面的代碼，但它給出了我也在下面提到的錯誤。歡迎任何幫助。使用javax.mail發送消息

Properties prop = new Properties(); 
    Session sess = Session.getDefaultInstance(prop,null); 

    Message msg = new MimeMessage(sess); 
    msg.setFrom(new InternetAddress("[email protected]", "Sender")); 
      msg.addRecipient(Message.RecipientType.TO, 
         new InternetAddress("[email protected]", "Receiver")); 
      msg.setSubject("Your Example.com account has been activated"); 
      msg.setText("Testing messgage"); 
      Transport.send(msg); 


}

產生的錯誤是

您設置的屬性的SMTP服務器對象在自己的機器（本地主機），這顯然是不運行在端口上的SMTP服務器25.我認爲你想使用現有的SMTP服務器（例如你從互聯網提供商那裏獲得的服務器，或者GMail爲你提供的服務器等等）。

是的，我想用戶的Gmail – user2575804

下面的示例性使用Gmail發送電子郵件：

private Properties createConfiguration() { 
    return new Properties() {{ 
     put("mail.smtp.auth", "true"); 
     put("mail.smtp.host", "smtp.gmail.com"); 
     put("mail.smtp.port", "587"); 
     put("mail.smtp.starttls.enable", "true"); 
    }}; 
}
