我已使用JMS在我的Web应用程序中成功发送了电子邮件，但结果仅以纯文本显示。我希望内容能够显示html。我该怎么做？这大致是我所拥有的：
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.setContent(message, "text/html; charset=utf-8");
msg.setSentDate(new Date());
Transport.send(msg);
}catch(MessagingException me){
logger.log(Level.SEVERE, "sendEmailNotification: {0}", me.getMessage());
}
根据Javadoc，MimeMessage#setText()设置默认的mime类型text/plain，而你需要text/html。而是使用MimeMessage#setContent()代替。
message.setContent(someHtmlMessage, "text/html; charset=utf-8");
有关其他详情，请参阅：
你可以使用setText(java.lang.String text,
boolean html)的MimeMessageHelper：
MimeMessage mimeMsg = javaMailSender.createMimeMessage();
MimeMessageHelper msgHelper = new MimeMessageHelper(mimeMsg, false, "utf-8");
boolean isHTML = true;
msgHelper.setText("<h1>some html</h1>", isHTML);
但你需要：
mimeMsg.saveChanges();
之前：
javaMailSender.send(mimeMsg);
设置内容类型。看看这个method。
message.setContent("<h1>Hello</h1>", "text/html");
如果您使用的是Google应用引擎/ Java，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);
你得打电话
msg.saveChanges();
设置内容类型后。
从JavaMail 1.4版开始，setText方法有一个重载接受子类型。
// 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" );
看看http://commons.apache.org/email/他们有一个HtmlEmail类，它可能完全符合你的需要。
您可以在这里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，Send email message using java application
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");
“loginVo.htmlBody（messageBodyPart）;”将包含html格式设计的信息，但在邮件中不接收它。

我发现这种方式不确定它适用于所有CSS原语
通过将标题属性“Content-Type”设置为“text / html”
mimeMessage.setHeader("Content-Type", "text/html");
现在我可以做类似的事情
mimeMessage.setHeader("Content-Type", "text/html");
mimeMessage.setText ("`<html><body><h1 style =\"color:blue;\">My first Header<h1></body></html>`")
问候
