带有字节数组的邮件附件 [英] Mail Attachments with byte array

问题描述

我有一个名为lSession的javax.mail.Session和一个MimeMessage lMessage：

I got a javax.mail.Session named lSession, and a MimeMessage lMessage :

Session lSession = Session.getDefaultInstance(properties);
MimeMessage lMessage = new MimeMessage(lSession);

我有一个包含文件表示的字节数组列表：

I got a List of Byte Array who contains file's representations :

List <byte[]> pPiecesJointes

我尝试将这些文件附加到邮件中，但我无法修复它... 。

I try to attach these file to the message, but I can't fix it....

if(!pPiecesJointes.isEmpty()){
    lMultipart = new MimeMultipart();
    lMessageBodyPart = new MimeBodyPart();
    // text message
    lMessageBodyPart.setText(pMessage);
    lMultipart.addBodyPart(lMessageBodyPart);
    for(int i = 0; i < pPiecesJointes.size(); i++){
        lMessageBodyPart = new MimeBodyPart();
        /* ?????? How add attachment in lMessageBodyPart with a Byte Array ?
        */ 
        lMultipart.addBodyPart(lMessageBodyPart);
    }
    lMessage.setContent(lMultipart);
}

Transport.send(lMessage);

请问，如果有人知道谁用文件数组附加文件？

Please, if somebody knows who attach the file with a byte array ?

推荐答案

试用此代码：

 MimeBodyPart att = new MimeBodyPart(); 
ByteArrayDataSource bds = new ByteArrayDataSource(bytearray, "AttName"); 
att.setDataHandler(new DataHandler(bds)); 
att.setFileName(bds.getName());
