我正在使用类似以下的内容将已发送消息的副本保存在 JavaMail 的用户已发送文件夹中。它适用于没有附件的电子邮件和附件小于 1MB 的电子邮件。但是对于大于 1MB 的附件,程序在实际执行代码之前就停止了。知道如何处理这个吗?
String host = ReadConfigPropertiesFile.getPropertyValue("server.host");
String smtpHost = ReadConfigPropertiesFile.getPropertyValue("smtp.host");
String from = "test@myserver.net";
String to = "test@myserver.net";
// Get system properties
Properties properties = System.getProperties();
// Setup smtp mail server
properties.setProperty(smtpHost, host);
properties.setProperty("mail.mime.encodeparameters", "true");
// properties.setProperty("mail.mime.decodeparameters","true");
properties.setProperty("mail.mime.encodefilename", "true");
// properties.setProperty("mail.mime.decodefilename","true");
// Get the default Session object.
Session session = Session.getDefaultInstance(properties);
// Define message
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(to));
message.setSubject("Peace ", "UTF-8");
// Create the message part
BodyPart messageBodyPart = new MimeBodyPart();
// Fill the message body
messageBodyPart.setContent("Hello attachment", "text/html; charset=UTF-8");
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
String[] filename = {"C:/Users/Dake/Desktop/music.mp3"};
for (int i = 0; i < filename.length; i++) {
// Part two is attachment
messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource(filename[i]);
messageBodyPart.setDataHandler(new DataHandler(source));
// messageBodyPart.setFileName(filename[i]);
//messageBodyPart.setHeader("Content-Type", "text/plain; charset=UTF-8; name="+MimeUtility.encodeText(filename[i]));
// messageBodyPart.setHeader("Content-ID", filename[i]);
messageBodyPart.setFileName(MimeUtility.encodeText(filename[i], "UTF-8", null)); //encode filename
//bodyPart.setFileName(MimeUtility.encodeText(attachment.getName(), "UTF-8", null));
multipart.addBodyPart(messageBodyPart);
}
// Put parts in message
message.setContent(multipart);
//set the time
DateFormat df = new SimpleDateFormat("dd/MM/yyyy HH:MM:SS");
Date date = new Date();
String sentDate = df.format(date);
Date dd = (Date) df.parse(sentDate);
message.setSentDate(date);
// Send the message
Transport.send(message);
System.out.println("Message sent...");
// Copy message to "Sent Items" folder as read
Store store = session.getStore("imap");
store.connect(host, "user", "userpwd");
Folder folder = (Folder) store.getFolder("Sent");
if (!folder.exists()) {
folder.create(Folder.HOLDS_MESSAGES);
}
folder.open(Folder.READ_WRITE);
System.out.println("appending...");
// folder.appendMessages(new Message[]{message});
try {
folder.appendMessages(new Message[]{message});
// Message[] msgs = folder.getMessages();
message.setFlag(FLAGS.Flag.RECENT, true);
} catch (Exception ignore) {
System.out.println("error processing message " + ignore.getMessage());
} finally {
store.close();
// folder.close(false);
}
System.out.println("Msg send and saved ....");
}
当我运行上面的代码时,它会显示附加......并且它永远停在那里。我使用 Apache James server 3.0-beta4 作为邮件服务器。
