如何同时发送带有纯文本和HTML文本的邮件，以便每个邮件阅读器都可以选择适合的格式?

问题描述

来自 http://www.oracle.com/technetwork/java/faq-135477.html#sendmpa :

有人可以给我看一些示例代码吗?

Can someone show me some sample code for this?

推荐答案

这是我自己的代码的一部分:

This is a part of my own code:

        final Message msg = new MimeMessage(session);
        msg.setFrom(new InternetAddress(senderAddress, senderDisplayName));
        msg.addRecipient(Message.RecipientType.TO,
                new InternetAddress(m.getRecipient(), m.getRecipientDisplayName()));
        msg.setSubject(m.getSubject());
        // Unformatted text version
        final MimeBodyPart textPart = new MimeBodyPart();
        textPart.setContent(m.getText(), "text/plain");
        // HTML version
        final MimeBodyPart htmlPart = new MimeBodyPart();
        htmlPart.setContent(m.getHtml(), "text/html");
        // Create the Multipart.  Add BodyParts to it.
        final Multipart mp = new MimeMultipart("alternative");
        mp.addBodyPart(textPart);
        mp.addBodyPart(htmlPart);
        // Set Multipart as the message's content
        msg.setContent(mp);
        LOGGER.log(Level.FINEST, "Sending email {0}", m);
        Transport.send(msg);

m是我自己的类的实例.

Where m is an instance of my own class.
