SFTP Adapters
Spring Integration provides support for file transfer operations over SFTP.
The Secure File Transfer Protocol (SFTP) is a network protocol that lets you transfer files between two computers on the Internet over any reliable stream.
The SFTP protocol requires a secure channel, such as SSH, and visibility to a client’s identity throughout the SFTP session.
Spring Integration supports sending and receiving files over SFTP by providing three client side endpoints: inbound channel adapter, outbound channel adapter, and outbound gateway. It also provides convenient namespace configuration to define these client components.
Starting with version 6.0, an outdated JCraft JSch client has been replaced with modern Apache MINA SSHD framework.
This caused a lot of breaking changes in the framework components.
However, in most cases, such a migration is hidden behind Spring Integration API.
The most drastic changed has happened with a DefaultSftpSessionFactory which is based now on the org.apache.sshd.client.SshClient and exposes some if its configuration properties.
