推荐答案
你所做的一切都是正确的，我正在使用gmail和我需要点击显示图片查看电子邮件中的图片，你可以添加以下行来查看图片：
All what you are doing is correct, I'm using gmail and I need click on "Display Images" to see images in emails, you can add following line to see image:
mbp2.setFileName("image.png");
我的完整代码如下所示：
My full code looks as this:
// create a message
MimeMessage msg = new MimeMessage(session);
msg.setRecipients(Message.RecipientType.TO, to);
msg.setSubject(subject);
// create and fill the first message part
MimeBodyPart mbp1 = new MimeBodyPart();
mbp1.setContent(bodyText, "text/html");
// create the second message part
MimeBodyPart mbp2 = new MimeBodyPart();
// attach the file to the message
DataSource source = new FileDataSource(new File("image.png"));
mbp2.setDataHandler(new DataHandler(source));
mbp2.setFileName("image.png");
mbp2.setHeader("Content-ID", "<image_cid>"); // cid:image_cid
// create the Multipart and add its parts to it
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp1);
mp.addBodyPart(mbp2);
// add the Multipart to the message
msg.setContent(mp);
// send the message
Transport.send(msg);
和html消息正文如下：
and html message body is this:
bodyText = "<p><img style='float:right' src='cid:image_cid'>Hello World example</p>";
