I have three issues in above email. 以上电子邮件中有三个问题。

1) B600003292 should be part of the subject, which should be " title is B600003292 ". 1） B600003292应该是主题的一部分，应该是“ title is B600003292 ”。 However, right now, the subject is "title is", and as you can see B600003292 was shown as the 1st line of the body. 但是，现在的主题是“标题是”，并且您可以看到B600003292被显示为正文的第一行。 How can I make the subject to be html formatted? 如何使主题变为html格式？

2) It has so much unexpected content being written to the email body and the actual body content I want, " <html>asdfb B600003292</html> ", is part of this non-sense and also not being transferred to html formatted body. 2）它有太多意外内容要写到电子邮件正文中，而我想要的实际正文内容“ <html>asdfb B600003292</html> ”属于这种<html>asdfb B600003292</html> ，不会转移到html格式的正文中。

3) There is no attachment. 3）没有附件。 I believe the encrypted code at the bottom is the attachment. 我相信底部的加密代码是附件。 Not sure why it is being shown as body content instead of a pdf. 不知道为什么将其显示为正文而不是pdf。

Below is my code. 下面是我的代码。

public void send(EmailType emailType) throws EmailException, MalformedURLException {
        org.apache.commons.mail.Email email;
        if (emailType == EmailType.SimpleEmail) {
            email = new SimpleEmail();
        } else if (emailType == EmailType.MultiPartEmail) {
            email = new MultiPartEmail();
            loadEmailAttachments(email);
        } else {
            email = new HtmlEmail();
            loadEmailAttachments(email);
        }
        email.setHostName(host);
        email.setSmtpPort(Integer.valueOf(port));
        //email.setAuthenticator(new DefaultAuthenticator(null, null));//.setAuthentication(new ());
        email.setCharset("utf-8");
        email.setFrom(from.getEmailAddress(), from.getDisplayName());
        for (TemplateEngineEmailer receiver : to) {
            email.addTo(receiver.getEmailAddress(), receiver.getDisplayName());
        }

        email.setSubject(subject);
        if (emailType == EmailType.HtmlEmail) {
            ((HtmlEmail) email).setHtmlMsg(body);
        } else {
            email.setMsg(body);
        }
        email.send();
    }

private void loadEmailAttachments(org.apache.commons.mail.Email email) throws EmailException, MalformedURLException {
    List<EmailAttachment> attachments = getEmailAttachment();
    if (attachments != null && !attachments.isEmpty()) {
        for (EmailAttachment attachment : attachments) {
            ((HtmlEmail) email).attach(attachment);
        }
    }
}

private List<EmailAttachment> getEmailAttachment() throws MalformedURLException {
    List<EmailAttachment> emailAttachments = new ArrayList<>();
    for (TemplateEngineAttachment attachment : attachments) {
        EmailAttachment emailAttachment = new EmailAttachment();
        if (attachment.isLocalFile()) {
            emailAttachment.setPath(attachment.getPath());
        } else {
            emailAttachment.setURL(new URL(attachment.getPath()));
        }
        emailAttachment.setDisposition(EmailAttachment.ATTACHMENT);
        emailAttachment.setDescription(attachment.getDescription());
        emailAttachment.setName(attachment.getName());
        emailAttachments.add(emailAttachment);
    }
    return emailAttachments;
}

Answer 1

It turns out the cause ruins everything is the html tag  in the subject. 事实证明，造成该主题的所有内容都是html标签的原因。 Once I remove it, everything works fine. 删除后，一切正常。
