推荐答案

如@ scary-wombat所述，您没有添加第一个参数.我想你打算这样做:

As @scary-wombat mentioned, you didn't add the first par. I suppose you meant to do:

... // add it multipart.addBodyPart(messageBodyPart); // second part (the image) ...

您还可以将Content-Disposition标头添加到图像部分:

You can also add a Content-Disposition header to the image part:

messageBodyPart.setDisposition(MimeBodyPart.INLINE);

更新:

对不起，您还必须向上移动多部分的创建:

Sorry, you must also move up the creation of multipart:

... // add it MimeMultipart multipart = new MimeMultipart("related"); multipart.addBodyPart(messageBodyPart); // second part (the image) ...

更新2:

尝试一下:

BodyPart messageBodyPart = new MimeBodyPart(); String htmlText = "<H1>Hello</H1><img src=\"cid:image\">"; messageBodyPart.setContent(htmlText, "text/html"); // add it MimeMultipart multipart = new MimeMultipart("related"); multipart.addBodyPart(messageBodyPart); // second part (the image) messageBodyPart = new MimeBodyPart(); java.io.InputStream inputStream = this.getClass().getResourceAsStream("/HappyBirthday.JPG"); ByteArrayDataSource ds = new ByteArrayDataSource(inputStream, "image/jpg"); System.out.println(inputStream); messageBodyPart.setDataHandler(new DataHandler(ds)); messageBodyPart.setHeader("Content-ID", "<image>"); messageBodyPart.setDisposition(MimeBodyPart.INLINE); multipart.addBodyPart(messageBodyPart); message.setContent(multipart); // Send message Transport.send(message);
