public static void smbPut(String remote_Url, String localFilePath) { InputStream in = null; OutputStream out = null; try { File localFile = new File(localFilePath); String fileName = localFile.getName(); SmbFile remoteFile = new SmbFile(remote_Url + "/" + fileName); in = new BufferedInputStream(new FileInputStream(localFile)); out = new BufferedOutputStream(new SmbFileOutputStream(remoteFile)); byte[] buffer = new byte[BUFFER_SIZE]; while ((in.read(buffer)) != -1) { out.write(buffer); buffer = new byte[1024]; System.out.println("上传成功....."); } } catch (Exception e) { e.printStackTrace(); } finally { try { if (out != null) out.close(); if (in != null) in.close(); } catch (IOException e) { e.printStackTrace(); } } } 服务端下载到本地磁盘
