JavaMail Api İle Email İşlemleri
JavaMail Api ile email gönderme ve alma işlemlerini gerçekleştirebilirsiniz. Email işlemlerini gerçekleştirmek için yazıda verilen kod örneklerini incelemeniz yeterlidir. Yazının sonunda kaynak kodlar Eclipse Java projesi olarak bulunmaktadır.
1. Java İle E-Mail Gönderme
IEMailSender.java interfaceini oluşturuyoruz. IEMailSender iki adet metod içeriyor birisi sendSimpleEMail diğeri ise sendEMailWithAttachment.

* nesnesi.
*
* @throws Exception

EMailSender.java classında IEMailSender.java interface inde bulunan sendSimpleEMail ve sendEMailWithAttachment metodları implement edildi. sendSimpleEmail metodu emailin sadece text olan kısmını gönderir, sendEMailWithAttachment metodu ise hem text hemde attachmentlari gönderir. Burada iki metod yazılmasındaki amaç Java Mail Api ile yapılabileceklerin gösterilmesidir.

Pop3EMailReader sınıfında getAllEMailList ve getNewEMailList metodlarını implement ediyoruz. getAllEMailList metodu email servis sağlayıcısında bulunan bütün mailleri alma işlemi gerçekleştirir, getNewEMailList metodu ise, email servis saplayıcısından, metoda verilen lastAccesingDate tarih degerinden sonra gelen bütün emailleri alır.

4. Email Servis Sağlayıcısından Emaillerin Alınması Örneği
Email servis sağlayıcısından emailleri almak için ReadEMailSample.java classını oluşturuyoruz.
package com.apps.email.sample;
import java.util.List;
import com.apps.email.model.EMail;
import com.apps.email.reader.Pop3EMailReader;
public class ReadEMailSample {
public static void main(String[] args) throws Exception {
String emailHost = "";
String userName = "";
String password = "";
String downloadDir = "";
Pop3EMailReader pop3EmailReader = new Pop3EMailReader(emailHost,userName,password);
List<EMail> emailListesi = pop3EmailReader.getAllEMailList(downloadDir);
for(EMail email : emailListesi) {
System.out.println("-----------------------------------------------------------");
System.out.println("Email From Adress : " + email.getFrom());
System.out.println("Email Subject : " + email.getSubject());
System.out.println("Email Message : " + email.getMessage());
System.out.println("***********************************************************");
}
}
}
DETAYLAR
1) Email Sevis Sağlayıcısından Emailler Alınırken Email Adreslerinin Format Problemi.
Pop3EMailReader.java classı 92. satır
/*
* Emailin from bilgisi aliniyor
*/
email.setFrom(MimeUtility.decodeText(InternetAddress.toString(messages[i].getFrom())));
MimeUtility classında bulunan static decodeText metodu format problemini çözüyor.
2) Email Servis Sağlayıcısından Emailler Alınırken Email Attchmentların Dosya İsimlerinin Format Problemi.
Pop3EMailReader.java classı 191. satır
String systemFileName = MimeUtility.decodeText(part.getFileName());
MimeUtility classında bulunan static decodeText metodu format problemini çözüyor.
3) Email Gönderme İşleminde Türkçe Karakter Problemi.
Simple email gönderilirken,
EMailSender.java classı 195.Satır. Simple email gonderilirken emailin contentine hangi charsetin kullanılacağı bilgisi verilir.
message.setContent(email.getMessage(), "text/html;charset=ISO-8859-9");
Attachmentlı email gönderilirken,
EMailSender.java classı 367.Satır. Attachmentlı email gönderilirken, gönderilen emailin text mesajının hangi karakter set ile gönderilmesi istendiği belirtiliyor “textPart.setText(email.getMessage(),“ISO-8859-9”);”
/**
* Multi part tanımlanıyor.
*/
Multipart multiPart = new MimeMultipart();
/**
* İlk önce text part tanımlanıp multi parta ekleniyor.
*/
MimeBodyPart textPart = new MimeBodyPart();
textPart.setText(email.getMessage(),"ISO-8859-9");
multiPart.addBodyPart(textPart);
