Azure Java SDK for blob-请求加载默认HttpClient提供程序，但在类路径上找不到

以下操作将获取此错误：

Caused by: java.lang.IllegalStateException: A request was made to load the default HttpClient provider but one could not be found on the classpath. If you are using a dependency manager, consider including a dependency on azure-core-http-netty or azure-core-http-okhttp. Depending on your existing dependencies, you have the choice of Netty or OkHttp implementations. Additionally, refer to https://aka.ms/azsdk/java/docs/custom-httpclient to learn about writing your own implementation.

当找不到HttpClient时，将发生错误。它似乎与代码无关。尝试检查您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

凭证（）

，它将返回以下错误：ResourceNotFound指定的资源不存在

无凭据访问公共blob：

它的工作原理是：

接受

将pom中的azure版本更改为12.9

导出AZURE_存储_帐户=AzureMLE示例

编辑如下

运行mvn编译exec:java

输出为：

正在列出容器中的blob： 这是blob名称：criteo-uplation-v2.1.csv.gz

这是blob名称：iris.csv

引发的错误：BlobServiceClient BlobServiceClient=new BlobServiceClientBuilder（）.endpoint(“是公共的，因此我希望无需凭据即可访问。我也尝试无需凭据即可访问公共blob，它也可以工作。我编辑回复以添加屏幕截图。请共享您遵循的步骤，最好共享您的代码。
