【问题描述】：

我正在尝试使用 SMB Java 库从共享驱动器访问文件。

我尝试了两种方式

a) 中小企业 JCIFS b) 神学

但是我得到异常的两种方式，下面是我得到的代码和异常

JCIFS

try {
            String path = "smb://" + remote_machine_name + "/" + sharedFolder+"/";
            NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("", remote_user_id, remote_user_password);
            SmbFile smbFile = new SmbFile(path, auth);
            System.out.println("Connected");
            SmbFile[] smbFileList = smbFile.listFiles();
            for (SmbFile file : smbFileList) {
                System.out.println(file.getName());
            }
            System.out.println("Done");
        } catch (SmbException se) {
            se.printStackTrace();
        }

例外：

jcifs.smb1.smb1.SmbException: Failed to connect: <hostname>/<ip address>
jcifs.smb1.util.transport.TransportException
java.net.SocketException: Connection reset

hierynomus smbj

SmbConfig cfg = SmbConfig.builder().withSecurityProvider(new BCSecurityProvider()).build();
        SMBClient client = new SMBClient(cfg);
        Connection connection;
        try {
            connection = client.connect(remote_machine_name);
            Session session = connection
                    .authenticate(new AuthenticationContext(remote_user_id, remote_user_password.toCharArray(), null));
            DiskShare share = (DiskShare) session.connectShare(sharedFolder);
            Set<FileAttributes> fileAttributes = new HashSet<>();
            fileAttributes.add(FileAttributes.FILE_ATTRIBUTE_DIRECTORY);
            Set<SMB2ShareAccess> shareAccesses = new HashSet<SMB2ShareAccess>();
            shareAccesses.add(SMB2ShareAccess.FILE_SHARE_READ);
            for (FileIdBothDirectoryInformation f : share.openDirectory(
                    "folder1/folder11/folder111",
                    EnumSet.of(AccessMask.FILE_READ_DATA), fileAttributes, shareAccesses,
                    SMB2CreateDisposition.FILE_OPEN, null)) {
                System.out.println(f.getFileName());
            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

异常（完整的堆栈跟踪）：

[main] INFO com.hierynomus.smbj.connection.Connection - Successfully connected to: **<hostname>**
[main] INFO com.hierynomus.smbj.connection.SMBSessionBuilder - Successfully authenticated karthik on **<hostname>**, session is -12346324324

    at com.hierynomus.smbj.share.DiskShare$2.apply(DiskShare.java:109)

我手动将网络驱动器映射到我的系统并验证我具有管理员权限，但由于某些原因，我收到了上述错误。

谁能帮我解决一下

【解决方案1】：

我从另一个答案中获得了 SMB JCIFS 方式的可能解决方案！

SmbException failed to connect hostname/IP_address throwing with proper credentials in Java

我认为问题在于您的系统中没有启用 SMB2（这是 Windows 10 所必需的），您需要创建一个 CIFSContext 对象以在本地电脑和共享文件夹之间建立正确的连接。
