无法使用 Spring javamail 在电子邮件中发送图像

Question

使用弹簧 4.0.8

这是我的代码

@Value("classpath:logo.png")
private Resource logoImage;

...

final MimeMessagePreparator preparator = new MimeMessagePreparator() {
            public void prepare(MimeMessage mimeMessage) throws Exception {
                final MimeMessageHelper message = new MimeMessageHelper(mimeMessage, true,"UTF-8");
                message.setTo(toEmail);
                message.setSubject("subject");
                message.setFrom(from);
                message.setReplyTo(replyTo);
                message.addInline("logo.png", logoImage);
                message.setText("<img src=\"cid:logo.png\"></img><div>My logo</div>", true);
            }
        };
        mailSender.send(preparator);

我收到没有图像的电子邮件。

当我调试它时 logoImage.exists() = true.

我做错了什么？

UPD：message.getMimeMessage().writeTo(System.out)打印这个：

    Reply-To: no-reply@sh.com
    To: kos@inbox.ru

添加后收到一条消息，我的帖子主要是代码，所以这里有一些文字，不要介意:)

看看这个例子。我认为你应该交换方法setText和addInline
