[FIXED] How can convert inputstream to InputStreamsource or Datasource to attach in Spring JavaMail

Issue

I am getting inputstream from the Jsch channelSFTP like below.

   ChannelSftp channelSftp = (ChannelSftp) channel;
   InputStream input = channelsftp.get(unixPath); // unixPath is path to my file which is on SFTP server

I have to attach the file in the unixPath in the Spring JavaMail attachment. But when I see API of Spring JavaMail addAttachment() method it takes only InputStreamSource or Datasource. My problem is I am not able to get the InputStreamSource or Datasource from the inputStream which I am getting form SFTP channel.

How Can I get InputStreamSource or Datasource from the above InputStream?

Solution

From the documentation, InputStreamSource is an interface. One of its implementations is InputStreamResource, which has a constructor that takes in an InputStream. Here is the JavaDoc for it.

You should be able to setup your call as such:

addAttachment("Not porn", new InputStreamResource(inputStream));
