Java实现迭代复制MinIo指定bucket下的文件

先上代码

    
      io.minio
      minio
      7.1.0
    

    
    public static void iterableCopyOfMinIoPath(MinioClient minioClient, String bucketName, String minIoPath, String targetPath){
        try {
            if (minioClient.bucketExists(bucketName)){
                Iterable> itemLists =
                        minioClient.listObjects(ListObjectsArgs.builder().bucket(bucketName).prefix(minIoPath).recursive(false).build());
                for (Result result : itemLists) {
                    Item item = result.get();
                    if (item.isDir()){
                        new File(targetPath+"\"+bucketName+"\"+item.objectName()).mkdirs();
                        iterableCopyOfMinIoPath(minioClient,bucketName,item.objectName(),targetPath);
                    }else {
                        InputStream inputStream = minioClient.getObject(GetObjectArgs.builder().bucket(bucketName)
                                .object(item.objectName()).build());
                        FileOutputStream fileOutputStream = new FileOutputStream(targetPath+"\"+bucketName+"\"+item.objectName());
                        int index;
                        byte[] bytes = new byte[1024];
                        while ((index = inputStream.read(bytes)) != -1) {
                            fileOutputStream.write(bytes, 0, index);
                            fileOutputStream.flush();
                        }
                        fileOutputStream.close();
                        inputStream.close();
                    }
                }
            }

        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

调用

亲测可用

 其中在

Iterable> itemLists =
                        minioClient.listObjects(ListObjectsArgs.builder().bucket(bucketName).prefix(minIoPath).recursive(false).build());

中:     .prefix(“”)方法添加如"AA/"后，itemLists即可获取到bucketName/AA/目录下的子文件/目录

PS:本人新手菜鸡，具体的就不太懂了
