Download attachments using Java Mail

Question

Now that I`ve downloaded all the messages, and store them to

Message[] temp;

How do I get the list of attachments for each of those message

Answer 1

You can simply use Apache Commons Mail API MimeMessageParser - getAttachmentList() along Commons IO and Commons Lang.

MimeMessageParser parser = ....
parser.parse();
for(DataSource dataSource : parser.getAttachmentList()) {

    if (StringUtils.isNotBlank(dataSource.getName())) {}

        //use apache commons IOUtils to save attachments
        IOUtils.copy(dataSource.getInputStream(), ..dataSource.getName()...)
    } else {
        //handle how you would want attachments without file names
        //ex. mails within emails have no file name
    }
}
