在Javamail附件中未显示
我尝试发送带有附件的邮件它正在发送和接收但在已接收邮件中附件未显示不显示附件为空,这里的代码是:
@Bean
public JavaMailSenderImpl mailSender() {
JavaMailSenderImpl javaMailSender = new JavaMailSenderImpl();
javaMailSender.setProtocol("smtp");
javaMailSender.setHost("smtp.gmail.com");
javaMailSender.setPort(587);
javaMailSender.setUsername("*******@gmail.com");
javaMailSender.setPassword("*********");
Properties props = ((JavaMailSenderImpl) javaMailSender).getJavaMailProperties();
props.put("mail.transport.protocol", "smtp");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.debug", "true");
props.put("mail.mime.multipart.allowempty", "true");
javaMailSender.setJavaMailProperties(props);
return javaMailSender;
}
{
message.setSubject(mailServiceDTO.getSubject());
message.setText(mailServiceDTO.getSubject(), "text/html");
MimeBodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setContent(mailServiceDTO.getSubject(), "text/html");
for (EmailAttachment attachment : mailServiceDTO.getAttachments()) {
message.addAttachment(attachment.getAttachmentName(), new ByteArrayResource(attachment.getAttachmentContent().getBytes()));
}
Multipart mp = new MimeMultipart();
mp.addBodyPart(messageBodyPart);
mimeMessage.setContent(mp);
javaMailSender.send(mimeMessage);
}
您可以在春季邮件中使用MimeMessageHelper。
示例
MimeMessage msg = javaMailSender.createMimeMessage();
MimeMessageHelper mailMessage = null;
List<PathSource> pathSourceList = request.getMailAttachList();
if (pathSourceList != null && pathSourceList.size() > 0)
mailMessage = new MimeMessageHelper(msg, true);
else
mailMessage = new MimeMessageHelper(msg, false);
// ....
if (pathSourceList != null && pathSourceList.size() > 0) {
for (PathSource filepath : pathSourceList) {
ByteArrayResource stream = new ByteArrayResource(DatatypeConverter.parseBase64Binary(
filepath.getData()));
mailMessage.addAttachment(filepath.getFileName(), stream);
}
}
try {
javaMailSender.send(mailMessage.getMimeMessage());
} catch (Exception ex) {
log.error("server info {}", serverModel.toString());
throw ex;
}
添加多个附件..
