[JAVA] Versuchen Sie, die Microsoft Azure SDK für SQL-API von Azure Cosmos DB Service 4.6 zu verwenden

Azure CosmosDB Java SDK Version 4.x wird 2020 veröffentlicht.

Die Verwendung wird im folgenden Dokument veröffentlicht, aber ich habe versucht, den Mindestcode für Hello World festzulegen. https://docs.microsoft.com/en-us/azure/cosmos-db/sql-api-sdk-java-v4

<dependency>
	<groupId>com.azure</groupId>
	<artifactId>azure-cosmos</artifactId>
	<version>4.6.0</version>
</dependency>

Sie können die Informationen, die Sie zum Herstellen einer Verbindung benötigen, im Azure-Portal abrufen.
