使用HTML正文和附件创建邮件实际上意味着创建一个内容为“多部分实体”的邮件,其中包含两部分,其中一部分是HTML内容,第二部分是附加文件。 / p>
这与您当前的代码不对应:
Multipart multipart = new MimeMultipart(); // creating a multipart is OK
// Creating the first body part of the multipart, it's OK
messageBodyPart = new MimeBodyPart();
// ... bla bla
// ok, so this body part is the "attachment file"
messageBodyPart.setDataHandler(new DataHandler(source));
// ... bla bla
multipart.addBodyPart(messageBodyPart); // at this point, the multipart contains your file attachment, but only that!
// at this point, you set your mail's body to be the HTML message
message.setContent(html, "text/html; charset=utf-8");
// and then right after that, you **reset** your mail's content to be your multipart, which does not contain the HTML
message.setContent(multipart);
此时,您的电子邮件内容是一个只有一部分的多部分,这是您的附件。
因此,要达到预期的结果,您应该采用不同的方式:
MimeBodyPart
大致翻译为:
Multipart multipart = new MimeMultipart(); //1
// Create the attachment part
BodyPart attachmentBodyPart = new MimeBodyPart(); //2
attachmentBodyPart.setDataHandler(new DataHandler(fileDataSource)); //2
attachmentBodyPart.setFileName(file.getName()); // 2
multipart.addBodyPart(attachmentBodyPart); //3
// Create the HTML Part
BodyPart htmlBodyPart = new MimeBodyPart(); //4
htmlBodyPart.setContent(htmlMessageAsString , "text/html"); //5
multipart.addBodyPart(htmlBodyPart); // 6
// Set the Multipart's to be the email's content
message.setContent(multipart); //7
