Class MimeMessageHelper

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

public class MimeMessageHelper
extends Object

Helper class for populating a MimeMessage.

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

Offers support for HTML text content, inline elements such as images, and typical mail attachments. Also supports 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 this helper, in order to let message population code interact with a simple message or a MIME message through a common interface.

Warning regarding multipart mails: Simple MIME messages that just contain HTML text but no inline elements or attachments will work on more or less any email client that is capable of HTML rendering. However, inline elements and attachments are still a major compatibility issue between email clients: It's virtually impossible to get inline elements and attachments working across Microsoft Outlook, Lotus Notes and Mac Mail. Consider choosing a specific multipart mode for your needs: The javadoc on the MULTIPART_MODE constants contains more detailed information.

Field Detail

MULTIPART_MODE_NO

public static final int MULTIPART_MODE_NO

Constant indicating a non-multipart message.

See Also:

Constant Field Values

MULTIPART_MODE_MIXED

public static final int MULTIPART_MODE_MIXED

Constant indicating a multipart message with a single root multipart element of type "mixed". Texts, inline elements and attachements will all get added to that root element.

This was Spring 1.0's default behavior. It is known to work properly on Outlook. However, other mail clients tend to misinterpret inline elements as attachments and/or show attachments inline as well.

See Also:

Constant Field Values

MULTIPART_MODE_RELATED

public static final int MULTIPART_MODE_RELATED

Constant indicating a multipart message with a single root multipart element of type "related". Texts, inline elements and attachements will all get added to that root element.

This was the default behavior from Spring 1.1 up to 1.2 final. This is the "Microsoft multipart mode", as natively sent by Outlook. It is known to work properly on Outlook, Outlook Express, Yahoo Mail, and to a large degree also on Mac Mail (with an additional attachment listed for an inline element, despite the inline element also shown inline). Does not work properly on Lotus Notes (attachments won't be shown there).

See Also:

Constant Field Values

MULTIPART_MODE_MIXED_RELATED

public static final int MULTIPART_MODE_MIXED_RELATED

Constant indicating a multipart message with a root multipart element "mixed" plus a nested multipart element of type "related". Texts and inline elements will get added to the nested "related" element, while attachments will get added to the "mixed" root element.

This is the default since Spring 1.2.1. This is arguably the most correct MIME structure, according to the MIME spec: It is known to work properly on Outlook, Outlook Express, Yahoo Mail, and Lotus Notes. Does not work properly on Mac Mail. If you target Mac Mail or experience issues with specific mails on Outlook, consider using MULTIPART_MODE_RELATED instead.

Method Detail

getMimeMessage

public final MimeMessage getMimeMessage()

Return the underlying MimeMessage object.

createMimeMultiparts

protected void createMimeMultiparts(MimeMessage mimeMessage,
                                    int multipartMode)
                             throws MessagingException

Determine the MimeMultipart objects to use, which will be used to store attachments on the one hand and text(s) and inline elements on the other hand.

Texts and inline elements can either be stored in the root element itself (MULTIPART_MODE_MIXED, MULTIPART_MODE_RELATED) or in a nested element rather than the root element directly (MULTIPART_MODE_MIXED_RELATED).

By default, the root MimeMultipart element will be of type "mixed" (MULTIPART_MODE_MIXED) or "related" (MULTIPART_MODE_RELATED). The main multipart element will either be added as nested element of type "related" (MULTIPART_MODE_MIXED_RELATED) or be identical to the root element itself (MULTIPART_MODE_MIXED, MULTIPART_MODE_RELATED).

Parameters:

mimeMessage - the MimeMessage object to add the root MimeMultipart object to

multipartMode - the multipart mode, as passed into the constructor (MIXED, RELATED, MIXED_RELATED, or NO)

Throws:

MessagingException - if multipart creation failed

setText

public void setText(String text)
             throws MessagingException

Set the given text directly as content in non-multipart mode or as default body part in multipart mode. Always applies the default content type "text/plain".

NOTE: Invoke addInline(java.lang.String, javax.activation.DataSource) after setText; else, mail readers might not be able to resolve inline references correctly.

Parameters:

text - the text for the message

Throws:

MessagingException - in case of errors

setText

public void setText(String text,
                    boolean html)
             throws MessagingException

Set the given text directly as content in non-multipart mode or as default body part in multipart mode. The "html" flag determines the content type to apply.

NOTE: Invoke addInline(java.lang.String, javax.activation.DataSource) after setText; else, mail readers might not be able to resolve inline references correctly.

Parameters:

text - the text for the message

html - whether to apply content type "text/html" for an HTML mail, using default content type ("text/plain") else

Throws:

MessagingException - in case of errors

setText

public void setText(String plainText,
                    String htmlText)

htmlText - the HTML text for the message

Throws:

MessagingException - in case of errors

addInline

public void addInline(String contentId,
                      DataSource dataSource)
               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(java.lang.String); 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.

dataSource - the javax.activation.DataSource to take the content from, determining the InputStream and the content type

Throws:

MessagingException - in case of errors

See Also:

addInline(String, java.io.File), addInline(String, org.springframework.core.io.Resource)

               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(java.lang.String); 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.

file - the File resource to take the content from

Throws:

MessagingException - in case of errors

addInline

public void addInline(String contentId,
                      Resource resource)
               throws MessagingException

Add an inline element to the MimeMessage, taking the content from a org.springframework.core.io.Resource.

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

NOTE: Invoke addInline after setText(java.lang.String); 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.

resource - the resource to take the content from

Throws:

MessagingException - in case of errors

See Also:

setText(java.lang.String), addInline(String, java.io.File), addInline(String, javax.activation.DataSource)

addInline

public void addInline(String contentId,
                      InputStreamSource inputStreamSource,
                      String contentType)
               throws MessagingException

Add an inline element to the MimeMessage, taking the content from an org.springframework.core.InputStreamResource, and specifying the content type explicitly.

You can determine the content type for any given filename via a Java Activation Framework's FileTypeMap, for example the one held by this helper.

Note that the InputStream returned by the InputStreamSource 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.

inputStreamSource - the resource to take the content from

contentType - the content type to use for the element

Throws:

MessagingException - in case of errors

addAttachment

public void addAttachment(String attachmentFilename,
                          DataSource dataSource)
                   throws MessagingException

Add an attachment 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.

Parameters:

attachmentFilename - the name of the attachment as it will appear in the mail (the content type will be determined by this)

dataSource - the javax.activation.DataSource to take the content from, determining the InputStream and the content type

Throws:

MessagingException - in case of errors

See Also:

addAttachment(String, org.springframework.core.io.InputStreamSource), addAttachment(String, java.io.File)

addAttachment

public void addAttachment(String attachmentFilename,
                          File file)
                   throws MessagingException

Add an attachment 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)!

Parameters:

attachmentFilename - the name of the attachment as it will appear in the mail

file - the File resource to take the content from

Throws:

MessagingException - in case of errors

See Also:

addAttachment(String, org.springframework.core.io.InputStreamSource), addAttachment(String, javax.activation.DataSource)

addAttachment

public void addAttachment(String attachmentFilename,
                          InputStreamSource inputStreamSource)
                   throws MessagingException

Add an attachment to the MimeMessage, taking the content from an org.springframework.core.io.InputStreamResource.

The content type will be determined by the given filename for the attachment. Thus, any content source will be fine, including temporary files with arbitrary filenames.

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

Parameters:

attachmentFilename - the name of the attachment as it will appear in the mail

inputStreamSource - the resource to take the content from (all of Spring's Resource implementations can be passed in here)

Throws:

MessagingException - in case of errors

addAttachment(String, java.io.File), addAttachment(String, javax.activation.DataSource), Resource

addAttachment

public void addAttachment(String attachmentFilename,
                          InputStreamSource inputStreamSource,
                          String contentType)
                   throws MessagingException

Add an attachment to the MimeMessage, taking the content from an org.springframework.core.io.InputStreamResource.

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

Parameters:

attachmentFilename - the name of the attachment as it will appear in the mail

inputStreamSource - the resource to take the content from (all of Spring's Resource implementations can be passed in here)

contentType - the content type to use for the element

Throws:

MessagingException - in case of errors

createDataSource

protected DataSource createDataSource(InputStreamSource inputStreamSource,
                                      String contentType,
                                      String name)

Create an Activation Framework DataSource for the given InputStreamSource.

Parameters:

inputStreamSource - the InputStreamSource (typically a Spring Resource)

contentType - the content type

name - the name of the DataSource

Returns:

the Activation Framework DataSource
