메일의 첨부 파일을 웹 환경에서 확인 할 경우 문제가 없고 outlook을 이용하여 확인 할 경우 '제목 없는 첨부 파일 날짜 .dat" 라고 첨부 파일이 변경되는 경우 처리 방안


참조 에서 가져온 코드 기준 수정


// File Name SendFileEmail.java import java.util.*; import javax.mail.*; import javax.mail.internet.*; import javax.activation.*; public class SendFileEmail { public static void main(String [] args) { // Recipient's email ID needs to be mentioned. String to = "abcd@gmail.com"; // Sender's email ID needs to be mentioned String from = "web@gmail.com"; // Assuming you are sending email from localhost String host = "localhost"; // Get system properties Properties properties = System.getProperties(); // Setup mail server properties.setProperty("mail.smtp.host", host); // Get the default Session object. Session session = Session.getDefaultInstance(properties); try { // Create a default MimeMessage object. MimeMessage message = new MimeMessage(session); // Set From: header field of the header. message.setFrom(new InternetAddress(from)); // Set To: header field of the header. message.addRecipient(Message.RecipientType.TO,new InternetAddress(to)); // Set Subject: header field message.setSubject("This is the Subject Line!"); // 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 = "file.txt"; DataSource source = new FileDataSource(filename); messageBodyPart.setDataHandler(new DataHandler(source)); //add attach file encode messageBodyPart.setFileName(MimeUtility.encodeText(fileName)); messageBodyPart.setHeader("Content-Type", "application/octet-stream;charset=utf-8"); messageBodyPart.setHeader("Content-Disposition", "attachment;filename="+MimeUtility.encodeText(fileName)+";"); //add attach file encode multipart.addBodyPart(messageBodyPart); // Send the complete message parts message.setContent(multipart ); // Send message Transport.send(message); System.out.println("Sent message successfully...."); }catch (MessagingException mex) { mex.printStackTrace(); } } }



두껍게 색칠 된것 처럼 인코딩 설정을 해야만, 문제 없이 표출된다.
