我已經使用JMS在Web應用程序中成功發送了電子郵件，但是結果僅以純文本顯示。我希望內容能夠顯示html。我該怎么做？這大致就是我所擁有的：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());}
