我正在使用 Ubuntu Server 来运行我的 java Spring boot(2.4.0) Jar 文件。这是我的代码
@Async
public void sendMessageWithAttachment(
EmailMapper emailMapper,List<multipartfile> files) throws MessagingException {
// ...
if (emailMapper != null) {
List<Subscriber> subscribers = kaleService.getAllSubscribers();
for (int index = 0; index < subscribers.size(); index++) {
MimeMessage message = emailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message,true);
helper.setTo(subscribers.get(index).getEmail());
helper.setFrom(kale_email_from);
helper.setSubject(emailMapper.getSubject());
helper.setText(emailMapper.getDescription());
if(files != null ) {
for (int indexOfFiles = 0; indexOfFiles < files.size(); indexOfFiles++) {
helper.addAttachment(files.get(indexOfFiles).getoriginalFilename(),files.get(indexOfFiles));
}
}
System.out.println("Sending email to : " + subscribers.get(index).getEmail());
emailSender.send(message);
}
}
}
