Spring Integration version 3.0 provides a new abstraction over the SftpSession object. The template provides methods to send, retrieve (as an InputStream), remove, and rename files. In addition, we provide an execute method to let the caller run multiple operations on the session. In all cases, the template takes care of reliably closing the session. For more information, see the Javadoc for RemoteFileTemplate There is a subclass for SFTP: SftpRemoteFileTemplate.spring-doc.cn

We added additional methods in version 4.1, including getClientInstance(). It provides access to the underlying ChannelSftp, which enables access to low-level APIs.spring-doc.cn

Version 5.0 introduced the RemoteFileOperations.invoke(OperationsCallback<F, T> action) method. This method lets several RemoteFileOperations calls be called in the scope of the same thread-bounded Session. This is useful when you need to perform several high-level operations of the RemoteFileTemplate as one unit of work. For example, AbstractRemoteFileOutboundGateway uses it with the mput command implementation, where we perform a put operation for each file in the provided directory and recursively for its sub-directories.
