考虑以下代码:
FileSystemManager fsManager = VFS.getManager();
FileObject sftpDir = fsManager.resolveFile("sftp://username:password@host/pub/downloads/");
FileObject child1 = sftpDir.getChild("child1.data");
FileObject child2 = sftpDir.getChild("child2.data");
InputStream s1 = child1.getContent().getInputStream();
InputStream s2 = child2.getContent().getInputStream();
在 Jsch 底层,是创建了两个单独的会话,还是一个会话和两个通道?
