java - smb 文件复制导致异常

Question

我正在尝试将 jar 文件复制到 Windows 共享文件夹，并且使用 smb 来执行此操作，但出现以下错误。还有其他方法可以复制文件吗？

    String user = "abc";
    String pass ="xyz";
    try{
        String sharedFolder="tmp/share/sample.jar";
        String path="smb://1.2.3.4/"+sharedFolder;
        NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("",user, pass);
        SmbFile smbFile = new SmbFile(path,auth);
        SmbFile localFile = new SmbFile("C:/abc/exz/sample.jar");
        localFile.copyTo(smbFile);

    }catch(Exception e){
        e.printStackTrace();
    }

异常:

我能够远程写入文件。

String sharedFolder="tmp/share/text.txt";
        String path="smb://1.2.3.4/"+sharedFolder;
        NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("",user, pass);
        SmbFile smbFile = new SmbFile(path,auth);
        SmbFileOutputStream smbfos = new SmbFileOutputStream(smbFile);
    smbfos.write("TEsting ".getBytes());

确保您使用的是最新的 jar，即 jcifs-1.3.15.jar，而不是 jcifs-1.1.11.jar 等较低版本。
