如何发送 HTML 电子邮件？

我已经成功地在我的 Web 应用程序中使用 JMS 发送电子邮件，但是结果只显示在纯文本中。我希望内容能够显示 html。我该怎么做？以下是我大致掌握的情况:

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。看看这个 方法。

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

看看 http://commons.apache.org/email/，他们有一个 HtmlEmail 类，可能正是您所需要的。

最佳答案

根据 Javadoc，MimeMessage#setText()设置默认的哑剧类型为 text/plain，而您需要的是 text/html。而是使用 MimeMessage#setContent()。

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

有关详细信息，请参阅:

如果你正在使用 Google app engine/Java，那么使用以下..。

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, 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");

你得打电话

msg.saveChanges();

设置内容类型后。

“ loginVo.htmlBody (messageBodyPart) ;”将包含 HTML 格式的设计信息，但是在邮件中不接收它。

从 JavaMail 版本1.4开始，就有一个接受子类型的 setText方法重载。

// 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" );

我发现这种方法不能确定它是否适用于所有的 CSS 原语

通过将头属性“ Content-Type”设置为“ text/html”

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

现在我可以做

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


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

问候

你可以使用 < a href = “ https://docs.spring.io/spring-Framework/docs/current/javadoc-api/org/springFramework/mail/javamail/MimeMessageHelper.html # setText-java.lang.String-boolean-”rel = “ nofollow norefrer”> setText (java.lang. String text, 布尔 html) from 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();

以前:

javaMailSender.send(mimeMsg);
