如何使用java将图片上传到云数据库中具有唯一public_id的特定文件夹？

import com.tencentcloudapi.common.Credential;
import com.tencentcloudapi.common.exception.TencentCloudSDKException;
import com.tencentcloudapi.common.profile.ClientProfile;
import com.tencentcloudapi.common.profile.HttpProfile;
import com.tencentcloudapi.common.profile.Language;
import com.tencentcloudapi.common.profile.Region;
import com.tencentcloudapi.cdb.v20170320.CdbClient;
import com.tencentcloudapi.cdb.v20170320.models.UploadImageRequest;
import com.tencentcloudapi.cdb.v20170320.models.UploadImageResponse;

public class ImageUploader {
    public static void main(String[] args) {
        // 配置云数据库的访问密钥和地域信息
        Credential cred = new Credential("your-secret-id", "your-secret-key");
        HttpProfile httpProfile = new HttpProfile();
        httpProfile.setEndpoint("cdb.tencentcloudapi.com");
        ClientProfile clientProfile = new ClientProfile();
        clientProfile.setHttpProfile(httpProfile);

        // 创建云数据库的客户端对象
        CdbClient client = new CdbClient(cred, "ap-guangzhou", clientProfile);

        // 构造图片上传请求
        UploadImageRequest req = new UploadImageRequest();
        req.setInstanceId("your-instance-id");
        req.setFileName("your-image-file-name.jpg");
        req.setImageUrl("your-image-url");
        req.setPath("your-specific-folder-path");
        req.setPublicId("your-unique-public-id");

        try {
            // 发送图片上传请求
            UploadImageResponse resp = client.UploadImage(req);

            // 处理上传结果
            System.out.println(resp.toString());
        } catch (TencentCloudSDKException e) {
            // 处理异常情况
            e.printStackTrace();
        }
    }
}
