DefaultSftpSessionFactory file resolving inconsistency

[m-terra]

Using Spring Boot 2.2.4 with Spring Integration SFTP 5.2.3

org.springframework.integration.sftp.session.DefaultSftpSessionFactory

Actual Behavior:
Property privateKey expects the prefix file: since it is resolved by Spring.
Property knownHosts does not work with file: prefix since it is passed directly to JCraft.

Expected Behavior:
Both properties privateKey and knownHosts work with file: prefix.

There is an API like this:

 /**
   * Sets the instance of <code>KnownHosts</code> generated with
   * <code>stream</code>.
   *
   * @param stream the instance of InputStream from known_hosts file.
   *
   * @throws JSchException
   *         if an I/O error occurs.
   *
   * @see com.jcraft.jsch.KnownHosts
   */
  public void setKnownHosts(InputStream stream) throws JSchException{ 

So, we indeed can have that knownHosts as a Resource as well and propagate its InputStream into JSch properly.

Feel free to contribute the fix, @andybaer !

Thanks for pointing this out!

@andybaer ,

Since you have not answered yet, but we are going to release tomorrow, I take an issue and will provide a Pull Request shortly.

Sorry for the late answer. I tried to get the build working behind the corporate proxy but failed to do so.

Thank you very much
