Question

我开始通过使用jCIFS来衡量我们失去的性能，而不是要求我们的用户自己手动映射驱动器，但后来我发现我甚至无法通过第一次基本的阅读测试使用jCIFS从文件中获取数据。

我将问题归结为测试问题：

import java.io.OutputStream;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

import com.google.common.io.ByteStreams;
import jcifs.smb.NtlmPasswordAuthentication;
import jcifs.smb.SmbFile;

public class TestCifs
{
    public static void main(String[] args) throws Exception
    {
        OutputStream output = ByteStreams.nullOutputStream();

        String domain = ""; // have tried the actual name too
        String user = "<your_user_here>";
        String pass = "<your_pass_here>";

        String relativePath = "path/to/100MiB";

        // Read via UNC path (Windows doing the SMB work.)
        Path uncFile = Paths.get("\\\\192.168.1.66\\Shared", relativePath);
        Files.copy(uncFile, output);

        // Read via jCIFS
        //TODO: Figure out if this is a real URL in which case we'd have to escape stuff.
        SmbFile smbFile = new SmbFile("smb://192.168.1.66/Shared/" + relativePath,
                                      new NtlmPasswordAuthentication(domain, user, pass));
        ByteStreams.copy(smbFile.getInputStream(), output);
    }
}

如果我运行它，它会运行直接拷贝，然后jCIFS拷贝失败并显示：

    at TestCifs.main(TestCifs.java:33)

我在user / pass中提供的用户名和密码与我在服务器上通过Windows安装其目录进行身份验证时使用的用户名和密码相同。我也尝试使用服务器的名称作为域无效。我真的对此感到茫然，我正要看看像Wireshark这样的东西来弄清楚实际上出了什么问题，但也许我做了一些明显错误的事情，而且有人可以指出这一点。

这可能是jCIFS＆＃39;的相关内容。自己的登录失败诊断：

似乎根本没有将用户名放入邮件中，所以也许我正在查看错误，但如果它真的这样做，肯定会被注意到之前是别人...

已尝试的解决方法：

将身份验证信息放入网址而不是auth对象。
在尝试访问SmbFile之前调用SmbSession.logon。在这种情况下，您只需从登录中获取错误。
使用NtlmAuthenticator.setDefault（）设置默认验证器。在这种情况下，您会看到它调用身份验证器来获取身份验证详细信息，但然后似乎丢弃了信息并在没有用户名的情况下发出请求。

jCIFS似乎无法进行身份验证
