无法使用 javamail 向 Gmail 发送 HTML 封电子邮件
Unable to send HTML emails using javamail to Gmail
我正在尝试使用 javamail 发送 html 电子邮件。这是我的功能：
private void sendBCCEmailWithoutAttachments(ArrayList<String> recipients
, String emailBody, final String senderEmail, final String senderPassword, String subject) {
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
Session session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(senderEmail, senderPassword);
}
});
session.setDebug(true);
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(senderEmail));
String addressList = "";
for (String st : recipients) {
addressList = addressList+"," + st;
}
addressList = addressList.substring(1);
message.setRecipients(Message.RecipientType.BCC,
InternetAddress.parse(addressList));
message.setSubject(subject);
Multipart multipart = new MimeMultipart();
BodyPart messageBodyPart = new MimeBodyPart();
// messageBodyPart.setHeader("Content-Type", "text/html");
messageBodyPart.setText(emailBody);
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart,"text/html");
message.saveChanges();
Transport.send(message);
System.out.println("Done");
} catch (MessagingException e) {
e.printStackTrace();
throw new RuntimeException(e);
}
}
从上面可以清楚地看出，我正在调用给定的 message.saveChanges() here 但它不起作用，这里消息的内容类型 header 仍然是 text/plain。

Content-Type: text/plain; charset=us-ascii

对于 html body，尽管设置为 text/plain 并执行 saveChanges() （请注意 header 行已被注释掉，但取消注释它们也给出相同的结果）
为什么会这样，解决方案是什么？
编辑：
messageBodyPart.setText(someText,"text/html") 不存在。检查这张图片。
我正在使用 javamail 1.4.7。
添加
MimeBodyPart messageBodyPart=new MimeBodyPart();
messageBodyPart.setContent(emailBody, "text/html");
// Add an attachment
attachmentBodyPart = new MimeBodyPart();
attachmentBodyPart.setDataHandler(new DataHandler(attachment));
attachmentBodyPart.setFileName(attachment.getName());
multipart.addBodyPart(attachmentBodyPart);
// and so on...
而不是
// messageBodyPart.setHeader("Content-Type", "text/html");
messageBodyPart.setText(emailBody);
