Need to show a specific name instead of username as display name to mail send via Spring boot smtp?-CodePudding

 SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom("[email protected]");
        message.setTo(recipients);
        message.setSubject("SERVICE DOWN");
        message.setText(".............");
        mailSender.send(message);

When using this, username is showing as display name. I want custom name like "SUPPORT"?

CodePudding user response：

As you can read on the API docs from Spring, you should use a different class: "Consider JavaMailSender and JavaMail MimeMessages for creating more sophisticated messages, for example messages with attachments, special character encodings, or personal names that accompany mail addresses."

SimpleMailMessage does not support that function. You have to use another class that does. A good alternative would be MimeMessageHelper. It is pretty straightforward to use and supports more functionalities.

Here is a simple example

First of all, a MailSender object is required. You could create one or create a bean out of it:

JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
mailSender.setHost("smtp.gmail.com");
mailSender.setPort(587);

mailSender.setUsername("[email protected]");
mailSender.setPassword("password");

Properties props = mailSender.getJavaMailProperties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.debug", "true");

Then send the message:

MimeMessagePreparator mailMessage = mimeMessage -> {

    MimeMessageHelper message = new MimeMessageHelper(
            mimeMessage, true, StandardCharsets.UTF_8);
    try {
        message.setFrom(senderEmail, senderName); // Here comes your name
        
        message.addTo(recipientEmail);  

        
        message.setReplyTo(senderEmail);
        message.setSubject(subject);
        message.setText(fallbackTextContent, htmlContent);
        
    } catch (Exception e) {
        throw new MailDeliveryServiceException(recipientEmail, e);
    }
};

mailSender.send(mailMessage);
