Class MimeMessageHelper

java.lang.Object
  org.springframework.mail.javamail.MimeMessageHelper

public class MimeMessageHelper
extends Object

Helper class for easy population of a javax.mail.internet.MimeMessage.

Mirrors the simple setters of SimpleMailMessage, directly applying the values to the underlying MimeMessage. Allows to define a character encoding for the entire message, automatically applied by all methods of this helper.

Also offers support for typical mail attachments, and for personal names that accompany mail addresses. Note that advanced settings can still be applied directly to the underlying MimeMessage object!

Typically used in MimeMessagePreparator implementations or JavaMailSender client code: simply instantiating it as a MimeMessage wrapper, invoking setters on the wrapper, using the underlying MimeMessage for mail sending. Also used internally by JavaMailSenderImpl.

Sample code for an HTML mail with an inline image and a PDF attachment:

 mailSender.send(new MimeMessagePreparator() {
   public void prepare(MimeMessage mimeMessage) throws MessagingException {
     MimeMessageHelper message = new MimeMessageHelper(mimeMessage, true, "UTF-8");
     message.setFrom("[email protected]");
     message.setTo("[email protected]");
     message.setSubject("my subject");
     message.setText("my text <img src='cid:myLogo'>", true);
     message.addInline("myLogo", new ClassPathResource("img/mylogo.gif"));
     message.addAttachment("myDocument.pdf", new ClassPathResource("doc/myDocument.pdf"));
   }
 });

Consider using MimeMailMessage (which implements the common MailMessage interface, just like SimpleMailMessage) on top of a MimeMessageHelper, to let message population code interact with a simple message or a MIME message through a common interface.

               throws MessagingException

Add an inline element to the MimeMessage, taking the content from a javax.activation.DataSource.

Note that the InputStream returned by the DataSource implementation needs to be a fresh one on each call, as JavaMail will invoke getInputStream() multiple times.

NOTE: Invoke addInline after setText; else, mail readers might not be able to resolve inline references correctly.

Parameters:

contentId - the content ID to use. Will end up as "Content-ID" header in the body part, surrounded by angle brackets: e.g. "myId" -> "<myId>". Can be referenced in HTML source via src="cid:myId" expressions.

               throws MessagingException

Add an inline element to the MimeMessage, taking the content from a java.io.File.

The content type will be determined by the name of the given content file. Do not use this for temporary files with arbitrary filenames (possibly ending in ".tmp" or the like)!

NOTE: Invoke addInline after setText; else, mail readers might not be able to resolve inline references correctly.

Parameters:

contentId - the content ID to use. Will end up as "Content-ID" header in the body part, surrounded by angle brackets: e.g. "myId" -> "<myId>". Can be referenced in HTML source via src="cid:myId" expressions.
