Freemarker is not displaying images on mail templates
Question
I've been trying to send images in my ftl templates but it is not working.
I tried base64, outlook works - gmail does not work I tried <img src="cid:logo" alt="logo"> outlook does not work - gmail does not work I tried with attachement also using cid outlook works - gmail doesnt...
How can I maje it work on both? Or at least make it work on gmail...
template.ftl
<!DOCTYPE html>
<html lang="en">
<head>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<img src="cid:logo.png" alt="logo">
</body>
</html>
Java code
@Service
public class EmailServiceImpl implements EmailService {
@Autowired
private Configuration freemarkerConfig;
@Autowired
private JavaMailSender sender;
@Override
public MailResponse sendEmail(final MailRequest mail, final String template, final Map<String, Object> model) {
final MailResponse response = new MailResponse();
final MimeMessage message = this.sender.createMimeMessage();
try {
final MimeMessageHelper helper = new MimeMessageHelper(message, true,
StandardCharsets.UTF_8.name());
final Template t = this.freemarkerConfig.getTemplate(template);
final String html = FreeMarkerTemplateUtils.processTemplateIntoString(t, model);
// addInline() not working at all...
// helper.addInline("logo.png", new ClassPathResource("logo.png"));
helper.addAttachment("logo.png", new ClassPathResource("logo.png"));
helper.setText(html, true);
helper.setTo(mail.getTo());
helper.setSubject(mail.getSubject());
helper.setFrom(mail.getFrom());
this.sender.send(message);
response.setMessage("mail send to : " + mail.getTo());
response.setSent(Boolean.TRUE);
} catch (MessagingException | IOException | TemplateException e) {
response.setMessage("Mail Sending failure : " + e.getMessage());
response.setSent(Boolean.FALSE);
}
return response;
}
}
As said before, addInline is not working at all, and I would like to make it work so I don't send images as attachments, which is not even working for gmail anyway...

You need to change the order of the helper commands. In my case I had the same problem as you had. For an inline attachment you need to use "helper.addInline", but the order matters.
The following is not working:
helper.addInline("logo.png", new ClassPathResource("logo.png"));
helper.setText(html, true);
But this is working:
helper.setText(html, true);
helper.addInline("logo.png", new ClassPathResource("logo.png"));
First, add the html via "setText", after you can add an inline attachment via "addInline".
This worked fine for me
