我有一个关于使用Samba

JCIFS访问文件的问题。因此，有一个我要访问的服务器，我们将其称为server.unv.edu，工作组为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。我得到了一个错误

任何人都可以给我建议或代码的正确性，以帮助我访问文件吗？

非常感谢。

回答：

您正在使它比应有的难度更大。请按照以下步骤操作，并确保您正在创建的共享文件夹对此正在使用的用户具有写权限。

  1. 下载jar文件http://jcifs.samba.org/（只有一个jar文件）

  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上运行此程序，想写入Windows框，因此如果您不知道如何在Windows上创建共享文件夹，请创建一个共享文件夹并将共享文件夹名称放在以下变量中…使用google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 !");
