使用JavaMail在电子邮件中嵌入图像
使用JavaMail在电子邮件中嵌入图像
提问于 2010-06-08 18:29:49
我想使用javamail发送一封带有内联图像的电子邮件。
我正在做这样的事情。
MimeMultipart content = new MimeMultipart("related");
BodyPart bodyPart = new MimeBodyPart();
bodyPart.setContent(message, "text/html; charset=ISO-8859-1");
content.addBodyPart(bodyPart);
bodyPart = new MimeBodyPart();
DataSource ds = new ByteArrayDataSource(image, "image/jpeg");
bodyPart.setDataHandler(new DataHandler(ds));
bodyPart.setHeader("Content-Type", "image/jpeg; name=image.jpg");
bodyPart.setHeader("Content-ID", "<image>");
bodyPart.setHeader("Content-Disposition", "inline");
content.addBodyPart(bodyPart);
msg.setContent(content);我也试过
bodyPart.setHeader("inline; filename=image.jpg");和
bodyPart.setDisposition("inline");但不管怎样，图像是以附件的形式发送的，内容处置正在变成“附件”。
如何使用javamail在电子邮件中内联发送图像？

你为什么不试试这样的东西呢？
MimeMessage mail = new MimeMessage(mailSession);
mail.setSubject(subject);
MimeBodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(message, "text/html");
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(new File("complete path to image.jpg"));
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(fileAttachment.getName());
messageBodyPart.setDisposition(MimeBodyPart.INLINE);
multipart.addBodyPart(messageBodyPart);
mail.setContent(multipart);在消息中，有一个<img src="image.jpg"/>标签，你应该没问题。
祝好运

这对我很有效：
MimeMultipart rootContainer = new MimeMultipart();
rootContainer.setSubType("related");
rootContainer.addBodyPart(alternativeMultiPartWithPlainTextAndHtml); // not in focus here
rootContainer.addBodyPart(createInlineImagePart(base64EncodedImageContentByteArray));
...
message.setContent(rootContainer);
message.setHeader("MIME-Version", "1.0");
message.setHeader("Content-Type", rootContainer.getContentType());
...
BodyPart createInlineImagePart(byte[] base64EncodedImageContentByteArray) throws MessagingException {
InternetHeaders headers = new InternetHeaders();
headers.addHeader("Content-Type", "image/jpeg");
headers.addHeader("Content-Transfer-Encoding", "base64");
MimeBodyPart imagePart = new MimeBodyPart(headers, base64EncodedImageContentByteArray);
imagePart.setDisposition(MimeBodyPart.INLINE);
imagePart.setContentID("<image>");
imagePart.setFileName("image.jpg");
return imagePart;Stack Overflow用户

下面是完整的代码
import java.awt.image.BufferedImage;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
private BodyPart createInlineImagePart() {
MimeBodyPart imagePart =null;
try
{
ByteArrayOutputStream baos=new ByteArrayOutputStream(10000);
BufferedImage img=ImageIO.read(new File(directory path,"sdf_email_logo.jpg"));
ImageIO.write(img, "jpg", baos);
baos.flush();
String base64String=Base64.encode(baos.toByteArray());
baos.close();
byte[] bytearray = Base64.decode(base64String);
InternetHeaders headers = new InternetHeaders();
headers.addHeader("Content-Type", "image/jpeg");
headers.addHeader("Content-Transfer-Encoding", "base64");
imagePart = new MimeBodyPart(headers, bytearray);
imagePart.setDisposition(MimeBodyPart.INLINE);
imagePart.setContentID("<sdf_email_logo>");
imagePart.setFileName("sdf_email_logo.jpg");
}
catch(Exception exp)
{
logError("17", "Logo Attach Error : "+exp);
}
return imagePart;
}
MimeMultipart mp = new MimeMultipart();
//mp.addBodyPart(createInlineImagePart());
mp.addBodyPart(createInlineImagePart());
