try (SftpFileSystem fs =
SftpClientFactory.instance().createSftpFileSystem(session);
ByteArrayOutputStream out = new ByteArrayOutputStream()
) {
Path targetPath = fs.getDefaultDir().resolve(path);
Files.copy(targetPath, out);
return out.toString("UTF-8");
}
} catch (SftpException e) {
log.error("download file:{} error:{}.", path, e.getMessage());
} catch (Exception e) {
log.error("download file:{} error.", path, e);
