如何发送HTML电子邮件？

134

我已经成功地使用JMS在我的Web应用程序中发送了电子邮件，但结果只以纯文本形式显示。我希望内容能够显示HTML。我该怎么做？这里大致是我的代码：

Message msg = new MimeMessage(mailSession);
try{
    msg.setSubject("Test Notification");
    msg.setRecipient(Message.RecipientType.TO, new InternetAddress(sentTo, false));
    String message = "<div style=\"color:red;\">BRIDGEYE</div>";
    msg.setText(message);
    msg.setSentDate(new Date());
    Transport.send(msg);
}catch(MessagingException me){
    logger.log(Level.SEVERE, "sendEmailNotification: {0}", me.getMessage());
}

设置内容类型。查看这个方法。

message.setContent("<h1>Hello</h1>", "text/html");

对于Groovy，请不要忘记将GString转换为java.lang.String。别忘了转换。 - it3xl

如果您正在使用Google应用引擎/Java，则请使用以下内容...

MimeMessage msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(SENDER_EMAIL_ADDRESS, "Admin"));
msg.addRecipient(Message.RecipientType.TO,
                 new InternetAddress(toAddress, "user");

msg.setSubject(subject,"UTF-8");

Multipart mp = new MimeMultipart();
MimeBodyPart htmlPart = new MimeBodyPart();
htmlPart.setContent(message, "text/html");
mp.addBodyPart(htmlPart);
msg.setContent(mp);
Transport.send(msg);

msg.setSubject(subject,"UTF-8");不起作用。应该使用msg.setSubject(subject);。 - Fizer Khan

@FizerKhan - 真的吗？https://docs.oracle.com/javaee/6/api/javax/mail/internet/MimeMessage.html#setSubject(java.lang.String,%20java.lang.String) - Nick Grealy

不起作用。它应该是msg.setSubject(subject,"UTF-8"); 和 htmlPart.setContent(message, "text/html; charset=utf-8"); - Bruno Lee

自JavaMail版本1.4以来，有一种重载的 setText 方法可以接受子类型。

// Passing null for second argument in order for the method to determine
// the actual charset on-the fly.
// If you know the charset, pass it. "utf-8" should be fine
msg.setText( message, null, "html" );

你需要调用

msg.saveChanges();

设置内容类型后。

请查看 http://commons.apache.org/email/，它们有一个名为HtmlEmail的类，可能正好符合您的需求。

我发现这种方式不确定是否适用于所有的CSS原语

通过将头部属性“Content-Type”设置为“text / html”

mimeMessage.setHeader("Content-Type", "text/html");

现在我可以做这样的事情了

mimeMessage.setHeader("Content-Type", "text/html");

mimeMessage.setText ("`<html><body><h1 style =\"color:blue;\">My first Header<h1></body></html>`")

你可以使用来自 MimeMessageHelper 的 setText(java.lang.String text, boolean html) 方法：

MimeMessage mimeMsg = javaMailSender.createMimeMessage();
MimeMessageHelper msgHelper = new MimeMessageHelper(mimeMsg, false, "utf-8");
boolean isHTML = true;
msgHelper.setText("<h1>some html</h1>", isHTML);

但是你需要：

mimeMsg.saveChanges();

之前：

javaMailSender.send(mimeMsg);

您可以在此处找到一个完整且非常简单的Java类，用于使用Google（Gmail）帐户发送电子邮件，使用Java应用程序发送电子邮件消息

它使用以下属性

Properties props = new Properties();
  props.put("mail.smtp.auth", "true");
  props.put("mail.smtp.starttls.enable", "true");
  props.put("mail.smtp.host", "smtp.gmail.com");
  props.put("mail.smtp.port", "587");

这完全没有回答问题。原帖的意思是要求发送特定的HTML电子邮件。 - Bassinator

“loginVo.htmlBody(messageBodyPart);”将包含HTML格式的设计信息，但在邮件中不会接收到它。

根据Javadoc文档，MimeMessage#setText()方法会默认设置邮件类型为text/plain，但你需要使用text/html类型。建议使用MimeMessage#setContent()方法代替。

message.setContent(someHtmlMessage, "text/html; charset=utf-8");
