如何使用Java中的jcifs将文件从smb共享复制到本地驱动器？ [英] How to copy file from smb share to local drive using jcifs in Java?

问题描述

有人可以帮我将文件从共享文件夹复制到本地驱动器吗？我的代码是：

Could anybody help me to copy file from shared folder to local drive? My code is:

import jcifs.smb.NtlmPasswordAuthentication;
import jcifs.smb.SmbFile;
import jcifs.smb.SmbFileInputStream;
import jcifs.smb.SmbFileOutputStream;;


public class smb {

      /**
      * @param args
      * @throws IOException
       */
      public static void main(String[] args) throws IOException {
            // TODO Auto-generated method stub


          String urlToBackUpFile = "smb://ip/backup$/test.txt"; 
          System.out.println("smb folder of source file" + urlToBackUpFile);
          NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(null, "login", "pass");


            SmbFile dir = new SmbFile(urlToBackUpFile, auth);
            System.out.println(dir.getDate());
            SmbFile dest = new SmbFile ("C:/SQLRESTORESTAGE/v2.bak");
            dir.copyTo(dest);
      }
}

不复制文件文件。我收到一条消息无法连接到服务器，但程序显示源文件的dir.getDate（）（和文件名，以及lenght）。所以我认为目标文件夹的问题（C：/ SQLRESTORESTAGE /）。另外，我只能阅读源文件。你能帮我修改代码或建议吗？谢谢。

File file is not copied. I received a message "Failed to connect to server", but the programm shows dir.getDate() (and file name, and lenght) of source file. So I think the problem with destination folder (C:/SQLRESTORESTAGE/). Also I have proviledges only for reading source file. Could you help me to cirrect the code or advise something? Thank you.

推荐答案

可能会在第二个文件中添加auth：

maybe adding auth to the second file:

SmbFile dest = new SmbFile ("C:/SQLRESTORESTAGE/v2.bak",**auth**);

使用 SmbFile dest = new SmbFile（C：/ SQLRESTORESTAGE，auth ）.canWrite
你知道你是否对父目录有写权限

using SmbFile dest = new SmbFile ("C:/SQLRESTORESTAGE",auth).canWrite you know if you have write permissions on the parent directory
