java - vfs2 和 samba(smb) 版本 2

Question

我们在 Windows 计算机中禁用了 smbv1，现在无法使用 smb2 进行连接 我们正在使用 commons-vfs2(2.0) 和 commons-vfs2-sandbox(2.0) 这是我的代码:

@Test
    public void testConnection() throws FileSystemException {
         String folder = "\\\\10.0.0.0\\smb";

        folder = folder.replaceAll("\\\\", "/");
        StringBuilder builder = new StringBuilder(128).append(Protocol.CIFS.getProtocolPrefix()).append(':')
                .append(folder);
        String fileURI = builder.toString();
        System.out.println(fileURI);

        FileSystemOptions fsOptions = null;

        String password = "mAdmin";
        String username = "myPassword";
        String domain = "";
        StaticUserAuthenticator auth = new StaticUserAuthenticator(domain, username, password);
        fsOptions = new FileSystemOptions();
        DefaultFileSystemConfigBuilder.getInstance().setUserAuthenticator(fsOptions, auth);
        FileSystemManager manager = VFS.getManager();

        FileSystemManager fileSystemManager = manager;
        FileObject fileObject = fileSystemManager.resolveFile(fileURI, fsOptions);
        boolean result = fileObject.isReadable();

        System.out.println(fileURI +" " + result);
    }

这就是我禁用 smb v1 的方法

Set-ItemProperty -路径“HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters”SMB1 -类型 DWORD -值 0 -强制

我如何启用 SMBV2

Set-ItemProperty -路径“HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters”SMB2 -类型 DWORD -值 1 -强制

https://support.microsoft.com/en-us/help/2696547/how-to-enable-and-disable-smbv1-smbv2-and-smbv3-in-windows-and-windows-server

如果我们启用 SMB1，它就可以工作

不幸的是commons-vfs2不支持SMBv2协议(protocol)。目前 SMBv2 客户端唯一的开源实现是 SMBJ 。使用 SMBJ，您可以按如下方式连接到您的共享:

SMBClient client = new SMBClient(SmbConfig.createDefaultConfig());
Connection c = client.connect("10.0.0.0");
Session s = c.authenticate(new AuthenticationContext("myAdmin", "myPassword", "");
DiskShare share = s.connectShare("smb");
