如何创建包含相同内容的文本和 HTML 版本的电子邮件？
当然，我想知道如何设置 freemarker 模板或将要发送的消息的标题。
当我查看我在收件箱中每隔一次收到的 MIME 格式的消息多部分消息的来源时，这就是其中的内容:
This is a multi-part message in MIME format.
------=_NextPart_000_B10D_01CBAAA8.F29DB300
Content-Type: text/plain
Content-Transfer-Encoding: 7bit
...Text here...
------=_NextPart_000_B10D_01CBAAA8.F29DB300
Content-Type: text/html;
charset="iso-8859-1"
Content-Transfer-Encoding: quoted-printable
<html><body> html code here ... </body></html>
最佳答案
如果您发现任何不一致之处，请告诉我。我必须从非常复杂的对象中提取它，这就是为什么它看起来像这样。
//some important imports
import freemarker.template.Template;
import org.springframework.mail.javamail.*;

message.setFrom(from);
message.setTo(recipient);
message.setSubject(subject);
// Now the message body.
Multipart mp = new MimeMultipart();
BodyPart textPart = new MimeBodyPart();
Template textTemplate = freemarkerConfig.getConfiguration().getTemplate(textEmailTemplate); // "/WEB-INF/emailText/*.ftl"
final StringWriter textWriter = new StringWriter();
textEmailTemplate.process(modelMap, textWriter);

pixPart.setContent(pixWriter.toString(), "text/html");
// Collect the Parts into the MultiPart
mp.addBodyPart(textPart);
mp.addBodyPart(pixPart);
// Put the MultiPart into the Message
message.setContent(mp);
}
};
executor.submit(new SendMail(preparator));
class SendMail extends Thread {
MimeMessagePreparator preparator;
SendMail(MimeMessagePreparator preparator) {
this.preparator = preparator;
}
public void run() {
mailSender.send(preparator);
}
}
