发送带有附件和消息的邮件

Question

为什么不能发送消息和附件当我使用下面的代码时，它将发送邮件和附件，但不发送消息。有人知道为什么或者怎么做吗?

工作代码，我使用了Java Mail 1.4.7 jar.

import java.util.Properties;
import javax.activation.*;
import javax.mail.*;
public class MailProjectClass {
public static void main(String[] args) {
    final String username = "[e-mail]";
    final String password = "your.password";
    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 {
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("[e-mail]"));
        message.setRecipients(Message.RecipientType.TO,
                InternetAddress.parse("[e-mail]"));
        message.setSubject("Testing Subject");
        message.setText("PFA");
        MimeBodyPart messageBodyPart = new MimeBodyPart();
        Multipart multipart = new MimeMultipart();
        messageBodyPart = new MimeBodyPart();
        String file = "path of file to be attached";
        String fileName = "attachmentName";
        DataSource source = new FileDataSource(file);
        messageBodyPart.setDataHandler(new DataHandler(source));
        messageBodyPart.setFileName(fileName);
        multipart.addBodyPart(messageBodyPart);
        message.setContent(multipart);
        System.out.println("Sending");
        Transport.send(message);
        System.out.println("Done");
    } catch (MessagingException e) {
        e.printStackTrace();
    }
  }
}

Answer 1

你需要添加邮件正文作为一个单独的多部分

String body="Email body template";
MimeBodyPart mailBody = new MimeBodyPart();
mailBody.setText(body);
multipart.addBodyPart(mailBody);

Answer 2

考虑到您在这里的String fileName = "attachmentName"由于拼写错误而遗漏了;

但除此之外，你的代码工作得很好
