我正在使用Java Mail API将文本文件(作为附件)附加到电子邮件中,但是当我运行程序时,它会复制文本文件内容并将其放入邮件正文而不是附件中
public class EmailCMSUsers {
public static void main(String args[])
{
Properties props = new Properties();
props.put("mail.smtp.host", "10.10.55.11");
props.put("mail.smtp.port", "25");
props.put("mail.smtp.starttls.enable", "true");
// To see what is going on behind the scene
//props.put("mail.debug", "true");
props.put("mail.from", "test123@mycompany.com");
Session session = Session.getInstance(props, null);
try {
MimeMessage msg = new MimeMessage(session);
msg.setFrom();
msg.setRecipients(Message.RecipientType.TO,"test123@mycompany.com");
msg.setSubject("JavaMail hello world example");
msg.setSentDate(new Date());
msg.setText("Hello, world!\n");
//Transport.send(msg);
msg.saveChanges();
/**
* for attaching the documents
*/
// Create the message part
BodyPart messageBodyPart = new MimeBodyPart();
// Fill the message
messageBodyPart.setText("This is message body");
// Create a multipar message
Multipart multipart = new MimeMultipart();
// Set text message part
multipart.addBodyPart(messageBodyPart);
// Part two is attachment
messageBodyPart = new MimeBodyPart();
String filename = "D:\\Deployment Docs\\Document.txt";
DataSource source = new FileDataSource(filename);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setDisposition(Part.ATTACHMENT);
messageBodyPart.setFileName(filename);
multipart.addBodyPart(messageBodyPart);
// Send the complete message parts
msg.setContent(multipart );
Transport transport = session.getTransport("smtp");
transport.connect("10.10.55.11", "test123", "test123");
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();
System.out.println(" email sucessfully sent");
} catch (MessagingException mex) {
System.out.println("send failed, exception: " + mex);
}
}
}

为什么你认为附件被放入邮件正文中?也许您的邮件阅读器显示附件,就好像它在邮件正文中一样?

我已经执行了您的代码,如果删除此行,它可以正常工作:
msg.saveChanges();
但是,使用此代码,通过邮件收到的附件的名称将包含路径:"D:\\Deployment Docs\\Document.txt"
。如果您想避免这种情况并仅使用规范名称(不包括路径:" Document.txt")发送文件,您可以按如下方式进行:
改变这个:
String filename = "D:\\Deployment Docs\\Document.txt";
DataSource source = new FileDataSource(filename);
//...
messageBodyPart.setFileName(filename);
为此:
File file = new File("D:\\Deployment Docs\\Document.txt");
DataSource source = new FileDataSource(file);
//...
messageBodyPart.setFileName(file.getName());
希望它对你有所帮助。
