不确定下面的版本是否是最优化的版本。但它似乎工作：

public static void deleteAtLocation(BlobContainerClient container, String historical) {
    if (checkIfPathExists(container, historical)) {
        List<BlobItem> collect = container.listBlobsByHierarchy(historical).stream().collect(Collectors.toList());
        for (BlobItem blobItem : collect) {
            String name = blobItem.getName();
            if (name.endsWith("/")) {
                deleteAtLocation(container, name);
            } else container.getBlobClient(name).delete();
        }
        container.getBlobClient(historical.substring(0, historical.length() - 1)).delete();
    }
}

public static boolean checkIfPathExists(BlobContainerClient container, String filePath) {
    BlobClient blobClient = container.getBlobClient(filePath);
    return blobClient.exists();
}

你只需要设置前缀并删除所有的子blob，如果文件夹中没有实际的blob，默认情况下文件夹将被删除。

public void deleteBlobs(BlobContainerClient blobContainerClient, String path){

    log.info("Deleting all blobs at {} in container {}", path, blobContainerClient.getBlobContainerName());

    ListBlobsOptions options = new ListBlobsOptions().setPrefix(path)
            .setDetails(new BlobListDetails().setRetrieveDeletedBlobs(false).setRetrieveSnapshots(false));
    blobContainerClient.listBlobs(options, null).iterator()
            .forEachRemaining(item -> blobContainerClient.getBlobClient(item.getName()).delete());
}
