Java上传文件到Windows共享目录问题 STATUS_ACCESS_DENIED（0xc000022）

Java上传文件到Windows共享目录问题

smpj上传到Windows共享目录一直失败，报STATUS_ACCESS_DENIED（0xc000022）。在GitHub上看错误码是服务器上报的，查看errortable是给到权限与服务器要求的权限不一致。openFile的第二个参数设置为添加文件和写文件即可（之前是全集操作GENERIC_ALL）。

File f = share.openFile(fileName, new HashSet(Arrays.asList(new AccessMask[]
{ AccessMask.FILE_ADD_FILE, AccessMask.FILE_WRITE_DATA })), fileAttributes, SMB2ShareAccess.ALL,
SMB2CreateDisposition.FILE_CREATE, createOptions);

String fileName =“EricTestFile.txt”;

// Connect to Share

}

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