java -minio.rar
您可以使用Minio的Java SDK来实现批量下载文件的功能。首先,您需要使用Minio的listObjects方法获取指定文件夹下的所有文件的objectName。您可以使用ListObjectsArgs.builder().recursive(true)来设置递归获取文件夹下的文件路径。然后,根据获取到的objectName逐个下载文件即可。
以下是一个示例代码片段,展示了如何使用Minio的Java SDK来实现批量下载文件的功能:
```java
import io.minio.MinioClient;
import io.minio.Result;
import io.minio.messages.Item;
import io.minio.errors.MinioException;
import java.util.ArrayList;
import java.util.List;
public class MinioDownloader {
private MinioClient minioClient;
public MinioDownloader() {
// 初始化MinioClient
minioClient = MinioClient.builder()
.endpoint("your-minio-endpoint")
.credentials("your-access-key", "your-secret-key")
.build();
}
public void downloadFilesInFolder(String folderPath, String destinationPath) {
try {
// 获取文件夹下的所有文件的objectName
List<String> objectNameList = getAllObjectNameInFolder(folderPath);
// 逐个下载文件
for (String objectName : objectNameList) {
minioClient.downloadObject("your-bucket", objectName, destinationPath + "/" + objectName);
}
System.out.println("Files downloaded successfully.");
} catch (Exception e) {
e.printStackTrace();
}
}
public List<String> getAllObjectNameInFolder(String folderPath) {
try {
ListObjectsArgs listObjectsArgs = ListObjectsArgs.builder()
.bucket("your-bucket")
.prefix(folderPath)
.recursive(true)
.build();
Iterable<Result<Item>> results = minioClient.listObjects(listObjectsArgs);
List<String> objectNameList = new ArrayList<>();
for (Result<Item> item : results) {
objectNameList.add(item.get().objectName());
}
return objectNameList;
} catch (Exception e) {
e.printStackTrace();
return new ArrayList<>();
}
}
}
```
请注意,您需要将代码中的"your-minio-endpoint"、"your-access-key"、"your-secret-key"和"your-bucket"替换为您自己的Minio配置信息。另外,您还需要指定下载文件的目标路径。
希望这可以帮助到您!
