"No MimeMessage content" exception when sending SimpleMailMessage
提问by Vincent F
I'm trying to send a very simple email with org.springframework.mail.javamail.JavaMailSenderImpl. Below is the code :
我正在尝试使用 org.springframework.mail.javamail.JavaMailSenderImpl 发送一封非常简单的电子邮件。下面是代码：
SimpleMailMessage mailMessage = new SimpleMailMessage();
mailMessage.setTo(request.getCustomerEmail());
mailMessage.setSubject("someSubject");
mailMessage.setFrom("[email protected]");
mailSender.send(mailMessage);
This is the exception I get :
这是我得到的例外：
Caused by: org.springframework.mail.MailSendException: Failed messages: javax.mail.MessagingException: No MimeMessage content
at org.springframework.mail.javamail.JavaMailSenderImpl.doSend(JavaMailSenderImpl.java:459)
at org.springframework.mail.javamail.JavaMailSenderImpl.send(JavaMailSenderImpl.java:307)
at org.springframework.mail.javamail.JavaMailSenderImpl.send(JavaMailSenderImpl.java:296)
I really don't understand why this happens..
我真的不明白为什么会发生这种情况..

After a couple of hours of struggling, I've found that this is all because the mail I'm creating has no text !
经过几个小时的努力，我发现这都是因为我创建的邮件没有文本！
If I add this line, then it works like a charm :
如果我添加这一行，那么它就像一个魅力：
mailMessage.setText("blabla");
I really got confused by the "No MimeMessage content" message.. Does anybody agree that the message could be more informative, or is it only me ? Does this mean we can't send an email with just a subject and no content ?
我真的被“没有 MimeMessage 内容”消息弄糊涂了。有人同意这条消息可以提供更多信息，还是只有我？这是否意味着我们不能发送只有主题而没有内容的电子邮件？
