我有一个关于使用 Samba JCIFS 访问文件的问题。

所以有一个我想访问的服务器，我们称之为server.unv.edu，工作组是WKGRP。

此服务器中有一个共享：\\server.unv.edu\pcb$

我尝试访问服务器的方式是：

public class SMBAuthenticator extends NtlmAuthenticator {

private String username = "username";
private String password = "password";
private String domain = "smb://server.unv.edu/WKGRP/";

public SMBAuthenticator() {
    NtlmAuthenticator.setDefault(this);
}

和

public class SMBConnection {

public String urlString = "smb://server.unv.edu/pcb$/path/file.txt";
NtlmPasswordAuthentication auth;
SmbFile smbFile;

public SMBConnection() throws MalformedURLException{;
    //url = new URL(urlString);
    SMBAuthenticator authenticator = new SMBAuthenticator();
    auth = authenticator.getNtlmPasswordAuthentication();   
    smbFile = new SmbFile(urlString, auth);
}

public InputStream getSMBInputStream() throws IOException{
    return this.smbFile.getInputStream();
}

public InputStream getInputStream() throws IOException{
    InputStream is = this.getSMBInputStream();
    return is;
}
}

但这不起作用。我得到一个错误：

谁能给我一个建议或我的代码的正确性，以帮助我访问该文件？

你让这变得比它应该的更难。请按照以下步骤操作，并确保您创建的共享文件夹对您正在使用的此用户具有写入权限。

  1. 下载jar文件http://jcifs.samba.org/（jar文件只有一个）
  2. 复制并粘贴以下代码以及您的用户名、密码和共享文件夹信息，这就是您所需要的

我在 Linux 上运行它并想写入 Windows 框，所以如果你不知道如何在 Windows 上创建共享文件夹，你想创建一个共享文件夹并将共享文件夹名称放在下面的变量中......使用谷歌一如既往

    String user = "your_user_name";
    String pass ="your_pass_word";

    String sharedFolder="shared";
    String path="smb://ip_address/"+sharedFolder+"/test.txt";
    NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("",user, pass);
    SmbFile smbFile = new SmbFile(path,auth);
    SmbFileOutputStream smbfos = new SmbFileOutputStream(smbFile);
    smbfos.write("testing....and writing to a file".getBytes());
    System.out.println("completed ...nice !");

/** You can simply use this util class for read write operations. **/

import java.io.IOException;
import java.io.OutputStream;
import java.net.MalformedURLException;
import java.net.UnknownHostException;
import java.nio.charset.StandardCharsets;

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

public class NDMUtil {

        String textToWrite) throws MalformedURLException, SmbException, UnknownHostException, IOException {
    NtlmPasswordAuthentication authentication = new NtlmPasswordAuthentication(domain, userName, password);
    try (OutputStream out = new SmbFileOutputStream(new SmbFile(sharedPath, authentication))) {
        byte[] bytesToWrite = textToWrite.getBytes();
        if (out != null && bytesToWrite != null && bytesToWrite.length > 0) {
            out.write(bytesToWrite);
        }
    }
    ;
}

public static String readFromNDM(String userName, String password, String domain, String sharedPath)
