如何发送HTML电子邮件？
我已经使用JMS成功地在我的Web应用程序中发送了电子邮件，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？ 这里大致是我所拥有的：
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MIMEtypes的text/plain ，而您需要text/html 。 而是使用MimeMessage#setContent()来代替。
message.setContent(someHtmlMessage, "text/html; charset=utf-8");
请注意，HTML不应包含<html> ， <head>或<body> 。 Gmail会忽略它。 另请参阅邮件客户端的CSS支持 。
设置内容types。 看这个方法 。
message.setContent("<h1>Hello</h1>", "text/html");
如果您正在使用Google App Engine / Java，请使用以下…
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);
你必须打电话
msg.saveChanges();
设置内容types后。
你可以在这里find一个完整的，非常简单的java类用于发送电子邮件使用谷歌（Gmail）帐户， 使用Java应用程序发送电子邮件
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格式的devise信息，但在邮件中不会收到它。

自JavaMail版本1.4以来，有一个覆盖接受子types的setText方法。
// 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" );
我发现这种方式不能确定它适用于所有的CSS基元
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东西
mimeMessage.setHeader("Content-Type", "text/html"); mimeMessage.setText ("`<html><body><h1 style =\"color:blue;\">My first Header<h1></body></html>`")
