Can'；t使用java检索azure存储Blob中Blob的元数据

我正在使用JavaAPI for azure，如下所述

在下面的代码示例中，我能够从BlobItem对象检索blob内容，但“metadata”除外，它返回null，尽管我已经在azure portal中手动向blob添加了元数据

BlobServiceClient blobServiceClient = new 
BlobServiceClientBuilder().connectionString(azConnectionString).buildClient();
BlobContainerClient blobContainerClient = blobServiceClient.getBlobContainerClient("myContainer")

ListBlobsOptions listsBlobOptions = new ListBlobsOptions();
listsBlobOptions.getDetails().getRetrieveMetadata();

blobContainerClient.listBlobs(listsBlobOptions, Duration.ofHours(1000)).forEach(blobItem -> {
    log.info(blobItem.getName());
    log.info(blobItem.getProperties().getETag());
    log.info(String.valueOf(blobItem.getProperties().getLeaseStatus()));
    log.info(String.valueOf(blobItem.getMetadata()));
  });

谢谢你的帮助

关于

我认为您没有获得元数据的原因是因为您没有元数据选项

您可以尝试以下内容（未经测试的代码）：

设置元数据选项解决了问题：）谢谢！

BlobServiceClient blobServiceClient = new 
BlobServiceClientBuilder().connectionString(azConnectionString).buildClient();
BlobContainerClient blobContainerClient = blobServiceClient.getBlobContainerClient("myContainer")

BlobListDetails blobListDetails = (new BlobListDetails()).setRetrieveMetadata(true);//set "retrieve metadata" option to true
ListBlobOptions listBlobOptions = (new ListBlobOptions()).setDetails(blobListDetails);

blobContainerClient.listBlobs(listsBlobOptions, Duration.ofHours(1000)).forEach(blobItem -> {
    log.info(blobItem.getName());
    log.info(blobItem.getProperties().getETag());
    log.info(String.valueOf(blobItem.getProperties().getLeaseStatus()));
    log.info(String.valueOf(blobItem.getMetadata()));
  });
