Spring 使用模板启动 java 邮件 html

Question

我正在使用 html 模板，该模板用作我的 JavaMail 中的内容。问题是 font-family 不工作。如果我运行浏览器上的 html 程序，它就可以工作。但是当作为电子邮件内容发送时，此字体不起作用。系统使用默认字体。

内容html：

<!DOCTYPE html>
<html lang="id">
<head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no">
    <title></title>
    <link rel="icon" href="#"/>
    <link href="https://fonts.googleapis.com/css2?family=Nunito:wght@300;400;600;700;800;900&display=swap" rel="stylesheet" />

    <style>
        body {
          font-family: 'Nunito', sans-serif;
          margin: 0;
        }
        .wrapper {
          width: 100%;
          max-width: 800px;
          margin: 0 auto;
          background-color: #ffffff;
          font-size: 14px;
        }
        .email-body {
          padding: 20px;
        }
    </style>
</head>
<body>
<div class="wrapper">
    <div class="email-body">
        <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Cras tempus at velit ac vehicula. 
           Sed ut porta augue, id cursus massa. Cras aliquam tempus lacus nec eleifend. Fusce enim odio,
           finibus eu ligula et, imperdiet placerat lorem. Fusce feugiat neque tincidunt, 
           placerat urna ullamcorper, laoreet tortor. Nulla congue ante eget odio egestas, ut eleifend justo volutpat. 
           Aliquam malesuada, quam nec pharetra ultrices, metus lacus elementum nisl, sed viverra eros nulla vitae nunc. Donec aliquet luctus mauris, sit amet dignissim risus lacinia id. Aliquam suscipit, turpis eu scelerisque tristique, mi turpis consequat sem, ac euismod elit turpis ac diam.</p>
    </div>
</div>
</body>
</html>

JavaMail.class

public void sendEmail(String host, String port, String username, String password, List<String> to, String subject, String content) throws MessagingException {
        
        Properties props = System.getProperties();
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", host);
        props.put("mail.smtp.port", port);
        props.put("mail.smtp.auth", "true");
        Session session = Session.getInstance(props, new Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(username,password);
            }
        });
        try {
            MimeMessage message = new MimeMessage(session);
            message.setFrom(new InternetAddress(username));
            InternetAddress[] toAddress = new InternetAddress[to.size()];

            for( int i = 0; i < to.size(); i++ )
                toAddress[i] = new InternetAddress(to.get(i));
            
            for( int i = 0; i < toAddress.length; i++)
                message.addRecipient(Message.RecipientType.TO, toAddress[i]);
            
            message.setSubject(subject);
            MimeBodyPart messageBodyPart = new MimeBodyPart();
            messageBodyPart.setText(content, "utf-8", "html"); //here the email template is inputted
            Multipart multipart = new MimeMultipart();
            multipart.addBodyPart(messageBodyPart);
            message.setContent(multipart);
            
            Transport transport = session.getTransport("smtp");
            transport.connect(host, username, password);
            transport.sendMessage(message, message.getAllRecipients());
            transport.close();

            logger.info("Send Email Success To : " + to.get(0));
        } catch (MessagingException e) {
            logger.info("Send Email Error Caused By : " + e.getMessage());
        }
    }

如何解决这个问题？

Answer 1

我把字体获取方法改成这样了。并且有效

已删除

<link href="https://fonts.googleapis.com/css2?family=Nunito:wght@300;400;600;700;800;900&display=swap" rel="stylesheet" />

在 <style> 标签内添加这个

@import url('https://fonts.googleapis.com/css2?family=Nunito:wght@300;400;600;700;800;900&display=swap');
