Envoi de pièces jointes à l'aide de Java

J'essaie d'envoyer des courriels en utilisant Java et g mail J'ai stocké mes fichiers sur le cloud et les fichiers stockés que je veux envoyer en pièce jointe à mon courrier.

Il faut ajouter que les fichiers à ce courrier et non les liens de ces fichiers.

Comment puis-je envoyer de telles pièces jointes?

Code de travail, j'ai utilisé 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();
    }
  }
}

Pour une raison inconnue, la réponse acceptée fonctionne partiellement lorsque j'envoie un courrier électronique à mon adresse Gmail. J'ai la pièce jointe mais pas le texte de l'email.

Si vous voulez à la fois une pièce jointe et du texte, essayez ceci en vous basant sur la réponse acceptée:

    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);
    }

À l'aide de Spring Framework, vous pouvez ajouter de nombreuses pièces jointes: 

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);
         }
}

Si vous me le permettez, cela fonctionne aussi pour les multi-pièces jointes , la première réponse de NINCOMPOOP ci-dessus, avec juste une petite modification comme suit: 

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);

Cela a fonctionné pour moi.

Ici, je suppose que ma pièce jointe est d'un format de type PDF.

Les commentaires sont faits pour le comprendre clairement. 

public class MailAttachmentTester {
    public static void main(String[] args) {
        // Recipient's email ID needs to be mentioned.
        String to = "[email protected]";
        // Sender's email ID needs to be mentioned
        String from = "[email protected]";
        final String username = "[email protected]";//change accordingly
        final String password = "test";//change accordingly
        // Assuming you are sending email through relay.jangosmtp.net
        Properties props = new Properties();
        props.put("mail.smtp.Host", "smtp.gmail.com");

        // Get the Session object.
        Session session = Session.getInstance(props,

                    }
                });
        try {
            // Create a default MimeMessage object.
            Message message = new MimeMessage(session);
            // Set From: header field of the header.
            message.setFrom(new InternetAddress(from));
            // Set To: header field of the header.
            message.setRecipients(Message.RecipientType.TO,
                    InternetAddress.parse(to));
            // Set Subject: header field

            // Create the message part
            BodyPart messageBodyPart = new MimeBodyPart();
            // Now set the actual message
            messageBodyPart.setText("Please find the attachment below");
            // Create a multipar message
            Multipart multipart = new MimeMultipart();
            // Set text message part
            multipart.addBodyPart(messageBodyPart);
            // Part two is attachment
            messageBodyPart = new MimeBodyPart();
            String filename = "D:/test.PDF";
            DataSource source = new FileDataSource(filename);
            messageBodyPart.setDataHandler(new DataHandler(source));
            messageBodyPart.setFileName(filename);
            multipart.addBodyPart(messageBodyPart);
            // Send the complete message parts
            message.setContent(multipart);
            // Send message
            Transport.send(message);
            System.out.println("Email Sent Successfully !!");
        } catch (MessagingException e) {
            throw new RuntimeException(e);
        }
    }
