Spring - Sending Mail with Attachment

Here’s an example to use Spring to send e-mail that has attachments via Gmail SMTP server. In order to contains the attachment in your e-mail, you have to use Spring’s JavaMailSender & MimeMessage , instead of MailSender & SimpleMailMessage.


Spring’s Mail Sender

You have to use JavaMailSender instead of MailSender to send attachments, and attach the resources with MimeMessageHelper. In this example, it will get the “c:\\log.txt” text file from your file system (FileSystemResource) as an e-mail attachment.

Beside file system, you can also get any resources from URL path(UrlResource), Classpath (ClassPathResource), InputStream (InputStreamResource)… please refer to Spring’s AbstractResource implemented classes.

To run the below example you need below jar files in your class path

• mail-1.4.1.jar
• spring-2.5.6.jar
• spring-jms.jar

TestMail.java

package com;

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 TestMail

{

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("C:\\Users\\vardhan\\Desktop\\log.txt");

helper.addAttachment(file.getFilename(), file);

}catch (MessagingException e) {

throw new MailParseException(e);

}

mailSender.send(message);

}

}

     ApplicationContext context = new ClassPathXmlApplicationContext("/applicationContext.xml");

     TestMail mm = (TestMail) context.getBean("mailMail");

     System.out.println("Before Sending Message >>>>>>>>>>>>>>>>>");
