如何解决gmail 怎么会显示使用 MimeMessageHelper addInline 附加的图像的“noname”附件?
当使用 Spring MimeMessageHelper 通过 addInLine 附加图标并使用 SES 发送时,一些图标显示为“noname”附件。 这些图像似乎是同一文件夹中随机未使用的图像。
AddInLine 代码
private void attachIconsInEmailBody(MimeMessageHelper messageHelper,String iconsPath) throws IOException,MessagingException {
Resource[] resources = resourcePatternResolver.getResources("classpath:" + iconsPath + "*.*");
for (Resource attRes: resources) {
String iconName = attRes.getFilename();
messageHelper.addInline(iconName.split("\\.")[0],attRes);
}
MimeMessage message = new MimeMessage(session);
MimeMessageHelper messageHelper = new MimeMessageHelper(message,true,"UTF-8");
messageHelper.setFrom(new InternetAddress(emailObject.getSender()));
messageHelper.setTo(InternetAddress.parse(emailObject.getRecipients()));
messageHelper.setSubject(emailObject.getSubject());
messageHelper.setText(htmlBody,true);
messageHelper.setSentDate(new Date(System.currentTimeMillis()));
// add all the icons in-line to display in the email body
attachIconsInEmailBody(messageHelper,"static/logo/SG/");
// send the email using the sendRawEmail API
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
message.writeto(outputStream);
RawMessage rawMessage = new RawMessage(ByteBuffer.wrap(outputStream.toByteArray()));
SendRawEmailRequest rawEmailRequest = new SendRawEmailRequest(rawMessage);
SendRawEmailResult emailResult = sesClient.sendRawEmail(rawEmailRequest);
// set the response back in the email object for any further recon
emailObject.setEmailResult(emailResult);
outputStream.close();
return emailResult;
