我在上述电子邮件中有三个问题。

1） <代码>

2）它有很多意想不到的内容被写入电子邮件正文和我想要的实际正文内容，”

3）没有附件。我相信底部的加密代码是附件。不确定为什么它显示为正文内容而不是pdf。

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;
}
