找不到httpclient时将发生错误。它似乎与代码无关。尝试检查是否遵循文档中的步骤。
我在app.java中尝试了以下代码，效果很好。

StorageSharedKeyCredential credential = new StorageSharedKeyCredential(accountName, accountKey);
BlobServiceClient blobServiceClient = new BlobServiceClientBuilder().endpoint(endpoint).credential(credential).buildClient();

如果删除 credential() ，它将返回此错误：resourcenotfound指定的资源不存在。
无凭据访问公共blob:

它的工作原理是：
采取https://github.com/azure-samples/azure-sdk-for-java-storage-blob-upload-download
将pom中的azure版本更改为12.9
导出azure\u storage\u account=azuremlexamples
编辑如下

运行mvn compileexec:java
输出为：
正在列出容器中的blob:https://azuremlexamples.blob.core.windows.net/datasets 这是blob名称：criteo-uplevation-v2.1.csv.gz这是blob名称：iris.csv
