Question

我正在尝试从共享驱动器读取文件但我收到错误

jcifs.smb.SmbException：无法连接到服务器 java.net.UnknownHostException：.. MSBROWSE 。＆lt; 01＆gt;

我已经厌倦了一些事情，但似乎没有任何工作。我将System.out.println（sFile.canRead（））改为true，这意味着连接成功。

public void readFilefromSharedDrive() throws IOException {
        String user = "user" + ":" + "pwd";
        NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(user);
        SmbFile sFile = null;
        try {
            sFile = new SmbFile("smb:///ip//path//filname.txt", auth);
            System.out.println(sFile.canRead());
            byte[] buffer = new byte[1024];
            try (SmbFileInputStream in = new SmbFileInputStream(sFile)) {
                int bytesRead = 0;
                do {
                    bytesRead = in.read(buffer);
                    // here you have "bytesRead" in buffer array
                } while (bytesRead > 0);

            } catch (Exception e) {
                JOptionPane.showMessageDialog(null, "ERROR: " + e);
            }
        } catch (MalformedURLException e1) {
            e1.printStackTrace();
        }
    }

它在SmbFileInputStream中抛出错误=新SmbFileInputStream（sFile）

这对我有用

 SmbFile smbfile = getSmbFile(newpath, getCredentials(user, password));

     public NtlmPasswordAuthentication getCredentials(String usr, String pwd) {
    NtlmPasswordAuthentication credentials = null;
    if(usr.length()==0){
        credentials = NtlmPasswordAuthentication.ANONYMOUS;
    }else {
        credentials = new NtlmPasswordAuthentication(null, usr,
                pwd);
    }
    return credentials;
}

无法使用java中的jcifs api从共享驱动器读取文件
