Mengirim lampiran surat menggunakan Java

Saya mencoba mengirim email menggunakan Java dan g mail. Saya telah menyimpan file saya di cloud dan file yang disimpan saya ingin kirim sebagai lampiran ke email saya.

Seharusnya menambahkan file itu ke email ini dan bukan tautan dari file-file itu.

Bagaimana saya bisa mengirim lampiran seperti itu?

Kode kerjanya, saya telah menggunakan Java Mail 1.4.7 jar

import Java.util.Properties;
import javax.activation.*;
import javax.mail.*;

public class MailProjectClass {

public static void main(String[] args) {

    final String username = "[email protected]";
    final String password = "your.password";

    Properties props = new Properties();
    props.put("mail.smtp.auth", true);
    props.put("mail.smtp.starttls.enable", true);
    props.put("mail.smtp.Host", "smtp.gmail.com");
    props.put("mail.smtp.port", "587");

    Session session = Session.getInstance(props,
            new javax.mail.Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(username, password);
                }
            });

    try {

        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("[email protected]"));
        message.setRecipients(Message.RecipientType.TO,
                InternetAddress.parse("[email protected]"));
        message.setSubject("Testing Subject");
        message.setText("PFA");

        MimeBodyPart messageBodyPart = new MimeBodyPart();

        Multipart multipart = new MimeMultipart();

        messageBodyPart = new MimeBodyPart();
        String file = "path of file to be attached";
        String fileName = "attachmentName";
        DataSource source = new FileDataSource(file);
        messageBodyPart.setDataHandler(new DataHandler(source));
        messageBodyPart.setFileName(fileName);
        multipart.addBodyPart(messageBodyPart);

        message.setContent(multipart);

        System.out.println("Sending");

        Transport.send(message);

        System.out.println("Done");

    } catch (MessagingException e) {
        e.printStackTrace();
    }
  }
}

Untuk alasan yang tidak diketahui, jawaban yang diterima sebagian berfungsi ketika saya mengirim email ke alamat gmail saya. Saya memiliki lampiran tetapi bukan teks dari email.

Jika Anda ingin lampiran dan teks coba ini berdasarkan jawaban yang diterima:

    Properties props = new Java.util.Properties();
    props.put("mail.smtp.Host", "yourHost");
    props.put("mail.smtp.port", "yourHostPort");
    props.put("mail.smtp.auth", "true");             
    props.put("mail.smtp.starttls.enable", "true");


    // Session session = Session.getDefaultInstance(props, null);
    Session session = Session.getInstance(props,
              new javax.mail.Authenticator() {
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication("user", "password");
                }
              });


    Message msg = new MimeMessage(session);
    try {
        msg.setFrom(new InternetAddress(mailFrom));
        msg.setRecipient(Message.RecipientType.TO, new InternetAddress(mailTo));
        msg.setSubject("your subject");

        Multipart multipart = new MimeMultipart();

        MimeBodyPart textBodyPart = new MimeBodyPart();
        textBodyPart.setText("your text");

        MimeBodyPart attachmentBodyPart= new MimeBodyPart();
        DataSource source = new FileDataSource(attachementPath); // ex : "C:\\test.pdf"
        attachmentBodyPart.setDataHandler(new DataHandler(source));
        attachmentBodyPart.setFileName(fileName); // ex : "test.pdf"

        multipart.addBodyPart(textBodyPart);  // add the text part
        multipart.addBodyPart(attachmentBodyPart); // add the attachement part

        msg.setContent(multipart);


        Transport.send(msg);
    } catch (MessagingException e) {
        LOGGER.log(Level.SEVERE,"Error while sending email",e);
    }

Menggunakan Spring Framework, Anda dapat menambahkan banyak lampiran: 

package com.mkyong.common;


import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.MailParseException;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;

public class MailMail
{
    private JavaMailSender mailSender;
    private SimpleMailMessage simpleMailMessage;

    public void setSimpleMailMessage(SimpleMailMessage simpleMailMessage) {
        this.simpleMailMessage = simpleMailMessage;
    }

    public void setMailSender(JavaMailSender mailSender) {
        this.mailSender = mailSender;
    }

    public void sendMail(String dear, String content) {

       MimeMessage message = mailSender.createMimeMessage();

       try{
        MimeMessageHelper helper = new MimeMessageHelper(message, true);

        helper.setFrom(simpleMailMessage.getFrom());
        helper.setTo(simpleMailMessage.getTo());
        helper.setSubject(simpleMailMessage.getSubject());
        helper.setText(String.format(
            simpleMailMessage.getText(), dear, content));

        FileSystemResource file = new FileSystemResource("/home/abdennour/Documents/cv.pdf");
        helper.addAttachment(file.getFilename(), file);

         }catch (MessagingException e) {
        throw new MailParseException(e);
         }
         mailSender.send(message);
         }
}

Jika Anda mengizinkan saya, berfungsi dengan baik juga untuk multi-lampiran , jawaban pertama NINCOMPOOP di atas, dengan sedikit modifikasi seperti berikut: 

DataSource source,source2,source3,source4, ...;  
source = new FileDataSource(myfile);  
messageBodyPart.setDataHandler(new DataHandler(source));  
messageBodyPart.setFileName(myfile);  
multipart.addBodyPart(messageBodyPart);  

source2 = new FileDataSource(myfile2);  
messageBodyPart.setDataHandler(new DataHandler(source2));  
messageBodyPart.setFileName(myfile2);  
multipart.addBodyPart(messageBodyPart);  

source3 = new FileDataSource(myfile3);  
messageBodyPart.setDataHandler(new DataHandler(source3));  
messageBodyPart.setFileName(myfile3);  
multipart.addBodyPart(messageBodyPart);  

source4 = new FileDataSource(myfile4);  
messageBodyPart.setDataHandler(new DataHandler(source4));  
messageBodyPart.setFileName(myfile4);  
multipart.addBodyPart(messageBodyPart);  

...

message.setContent(multipart);

Ini berhasil untuk saya.

Di sini saya menganggap lampiran saya adalah format tipe PDF.

Komentar dibuat untuk memahaminya dengan jelas. 

public class MailAttachmentTester {
    public static void main(String[] args) {
