java.net.UnknownHostException: ..__MSBROWSE__ 使用 jcifs 时

Question

我正在尝试将文件从本地目录复制到 windows 框上的网络共享。我正在使用 jcifs 1.3.17。我成功地连接到目的地，实际上在那里创建了文件，获得 "canWrite" 状态 "true"，但是当我尝试将本地文件的内容复制到远程文件时，我得到了以下错误：

jcifs.smb.SmbException: Failed to connect to server
java.net.UnknownHostException: ..__MSBROWSE__.<01>
   at jcifs.netbios.NbtAddress.doNameQuery(NbtAddress.java:317)

。 . .

代码片段：

        SmbFile source = new SmbFile(original);
        SmbFile dest = new SmbFile (target,auth);
        dest.createNewFile();
        boolean canWrite = dest.canWrite();
        source.copyTo(dest);

我不明白...如果我可以在目的地创建文件并且 smb 看到我可以写入它，为什么 doCopy 会失败？

Answer 1

我也不太明白但是...试试这个。有效！

    String source = "smb://SERVER/PATH/FILE";
    NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(null, "USERNAME", "PASSWORD");
    SmbFile sourceFile = new SmbFile(source, auth);
    String destination = "LOCAL_PATH_TO_FILE";

    byte[] buffer;
    int length;

    try {
        FileOutputStream fileOutputStream = new FileOutputStream(destination);
        InputStream fileInputStream = sourceFile.getInputStream();
        try {
            buffer = new byte[16 * 1024 * 1024];
            while ((length = fileInputStream.read(buffer)) > 0) {
                fileOutputStream.write(buffer, 0, length);
            }
        } finally {
            fileInputStream.close();
            fileOutputStream.close();
        }
    } catch (SmbException e) {
        // Error handling.    
    } catch (FileNotFoundException e) {
        // Error handling.
    } catch (IOException e) {
        // Error handling.
    }
