java代码连接SynologyNAS服务器实现文件从windows上传到SynologyNAS

下面是一个示例代码，使用Java的SMBJ库实现从Windows上传文件到Synology NAS：

import java.io.File;
import java.io.IOException;
import java.net.InetAddress;
import java.net.UnknownHostException;

import jcifs.smb.*;

public class SmbUploader {
    public static void main(String[] args) {
        try {
            String username = "username";
            String password = "password";
            String domain = "WORKGROUP";
            String sharedFolder = "sharedFolder";
            String filePath = "C:\\file.txt";
            String remoteFilePath = "/path/to/remote/file.txt";
            String serverName = "NAS_SERVER_NAME";

            NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(domain, username, password);
            SmbFile smbFile = new SmbFile("smb://" + serverName + "/" + sharedFolder + "/" + remoteFilePath, auth);

            // create local file object
            File localFile = new File(filePath);

            // create input stream for local file
            SmbFileOutputStream smbFileOutputStream = new SmbFileOutputStream(smbFile);
            smbFileOutputStream.write(IOUtils.toByteArray(new FileInputStream(localFile)));

            System.out.println("File uploaded successfully!");

        } catch (UnknownHostException e) {
            e.printStackTrace();
        } catch (SmbException e) {
            e.printStackTrace();
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

请注意，在上传文件之前，需要在Synology NAS上设置共享文件夹，并且确保Java程序有足够的权限访问该共享文件夹。
