java - 使用 Java 和 Samba JCIFS 访问文件

Question

我有一个关于使用 Samba JCIFS 访问文件的问题。

所以有一个我要访问的服务器，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。我收到以下错误:

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？

Answer 1

你让这件事变得比应该做的更难。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/ (只有一个jar文件)
2. 复制并粘贴以下代码，其中包含您的用户名、密码和共享文件夹信息，这就是您所需要的一切

我在 Linux 上运行它并想写入 Windows 框，因此您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 如果您不知道如何在 Windows 上创建共享文件夹...一如既往地使用 google

    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 !");
