// 设置OSS访问信息 String accessKeyId = "your_access_key_id" String accessKeySecret = "your_access_key_secret" String endpoint = "your_oss_endpoint" String bucketName = "your_bucket_name" // 设置下载的文件夹路径 String ossFolder = "your_oss_folder_path" String localFolder = "your_local_folder_path" // 创建OSS客户端 def ossClient = new com.aliyun.oss.OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret) // 列出指定前缀的所有文件 def fileList = ossClient.listObjects(bucketName, ossFolder).getObjectSummaries() // 创建本地文件夹 new File(localFolder).mkdirs() // 下载文件夹中的所有文件 fileList.each { String ossFilePath = it.getKey() String localFilePath = localFolder + "/" + ossFilePath.substring(ossFolder.length() + 1) if (!it.isDirectory()) { // 下载文件 def object = ossClient.getObject(bucketName, ossFilePath) def inputStream = object.getObjectContent() def outputStream = new FileOutputStream(localFilePath) byte[] buffer = new byte[1024] int bytesRead while ((bytesRead = inputStream.read(buffer)) != -1) { outputStream.write(buffer, 0, bytesRead) } outputStream.close() inputStream.close() } } // 关闭OSS客户端 ossClient.shutdown()修改这段代码，要求下载到本地时将整个文件夹都下载下来

要修改代码以下载整个文件夹，你需要对文件列表进行递归遍历，并在本地创建相应的文件夹结构。以下是修改后的代码示例：

import com.aliyun.oss.model.*;
import java.io.*;

// 设置OSS访问信息
String accessKeyId = "your_access_key_id";
String accessKeySecret = "your_access_key_secret";
String endpoint = "your_oss_endpoint";
String bucketName = "your_bucket_name";

// 设置下载的文件夹路径
String ossFolder = "your_oss_folder_path";
String localFolder = "your_local_folder_path";

// 创建OSS客户端
OSS ossClient = new OSSClientBuilder().build(endpoint, accessKeyId, accessKeySecret);

// 列出指定前缀的所有文件
List<OSSObjectSummary> fileList = ossClient.listObjects(bucketName, ossFolder).getObjectSummaries();

// 创建本地文件夹
new File(localFolder).mkdirs();

// 下载文件夹中的所有文件
downloadFiles(fileList, ossClient, bucketName, ossFolder, localFolder);

// 关闭OSS客户端
ossClient.shutdown();

// 递归下载文件夹中的所有文件
void downloadFiles(List<OSSObjectSummary> fileList, OSS ossClient, String bucketName, String ossFolder, String localFolder) {
    for (OSSObjectSummary objectSummary : fileList) {
        String ossFilePath = objectSummary.getKey();
        String localFilePath = localFolder + "/" + ossFilePath.substring(ossFolder.length() + 1);

        if (objectSummary.isDirectory()) {
            // 如果是文件夹，则递归下载其子文件夹中的文件
            ListObjectsRequest listObjectsRequest = new ListObjectsRequest(bucketName)
                    .withPrefix(ossFilePath + "/");
            ObjectListing objectListing = ossClient.listObjects(listObjectsRequest);
            List<OSSObjectSummary> subFolderFiles = objectListing.getObjectSummaries();
            downloadFiles(subFolderFiles, ossClient, bucketName, ossFilePath, localFolder);
        } else {
            // 如果是文件，则下载文件
            OSSObject object = ossClient.getObject(bucketName, ossFilePath);
            try (InputStream inputStream = object.getObjectContent();
                 OutputStream outputStream = new FileOutputStream(localFilePath)) {
                byte[] buffer = new byte[1024];
                int bytesRead;
                while ((bytesRead = inputStream.read(buffer)) != -1) {
                    outputStream.write(buffer, 0, bytesRead);
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

这样修改后的代码将递归地下载整个文件夹中的所有文件，并在本地创建相应的文件夹结构。请将 `your_access_key_id`、`your_access_key_secret`、`your_oss_endpoint`、`your_bucket_name`、`your_oss_folder_path`、`your_local_folder_path` 替换为实际的 OSS 访问信息和文件夹路径。
