如何将图像嵌入到速度html模板中,以便收件人可以在不打开文件的情况下阅读它?
我按照以下说明操作: http://sengopal.github.io/blog/blog/java-mail-using-velocity-templates.html
这是我的代码:
public class SendEmailVelocity {
public static void main(String[] args) {
final String username = Contants.myEmail;
final String password = Contants.myPass;
final String toMailRecipient = Contants.mailRecipient;
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");
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Template template = Velocity.getTemplate("helloworld.vm");
VelocityContext context = new VelocityContext();
context.put("name", "ABC123");
StringWriter message = new StringWriter();
template.merge(context, message);
MimeMultipart multipart = new MimeMultipart("related");
BodyPart imageBodyPart = new MimeBodyPart();
StringBuffer imgPath = new StringBuffer().append(File.separator).append("D:\\Temp\\data\\logo.gif");
DataSource fds = new FileDataSource(imgPath.toString());
imageBodyPart.setDataHandler(new DataHandler(fds));
imageBodyPart.setHeader("Content-ID", "<imageID>");
multipart.addBodyPart(imageBodyPart);
BodyPart messageBodyPart = new MimeBodyPart();
StringBuffer messageBuffer = new StringBuffer();
messageBuffer.append(message.toString());
messageBuffer.append("<img src='cid:imageID\'>");
messageBodyPart.setContent(messageBuffer.toString(), "text/html");
multipart.addBodyPart(messageBodyPart);
Message msg = new MimeMessage(session);
msg.setContent(multipart);
msg.addRecipients(Message.RecipientType.TO, InternetAddress.parse(toMailRecipient));
msg.setSubject("Test Email Velocity ");
msg.setSentDate(new Date());
msg.setFrom(new InternetAddress("dummy@example.com"));
Transport transport = session.getTransport("smtp");
transport.connect(props.getProperty("connectHost"), props.getProperty("connectUser"), props.getProperty("connectPassword"));
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();
System.out.println("Sent!!!");
} catch (MessagingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
但收件人电子邮件的结果是两个附件the recipient's email

这是一个较老的问题,但我今天遇到了谷歌搜索如何做同样的事情。我使用了Commons Email并按照以下说明操作:https://commons.apache.org/proper/commons-email/userguide.html
e.g。在我的模板中:
<img src="cid:${cid}" alt="Logo">
然后在我的Java代码中:
URL url = new URL("something.png");
String cid = email.embed(url, "Logo");
Map emailModel = new HashMap();
emailModel.put("cid", cid);
