使用Java的Azure Blob的StorageException

当我尝试为我的存储创建容器时，我得到StorageException。1.我创建了一个Azure帐户。2.我为blob创建了一个Azure存储。3.我写了一个简单的测试（如下）。4.我在本地计算机上编写了此代码，并得到了异常。怎么了？

public class Test {
public static final String storageConnectionString =
        "DefaultEndpointsProtocol=https;" +
                "AccountName=my_account;" +
                "AccountKey=my_account_key";


public static void main(String[] args) throws StorageException, InvalidKeyException, URISyntaxException {



    pushControll();

}

public static void pushControll() throws URISyntaxException, StorageException, InvalidKeyException {

        CloudStorageAccount storageAccount = CloudStorageAccount.parse(storageConnectionString);

        CloudBlobClient blobClient = storageAccount.createCloudBlobClient();


        CloudBlobContainer container = blobClient.getContainerReference("observer");

        container.create();




    }
}

我得到StorageException->：

流程以退出代码1完成

我做错了什么？
