Azure Cosmos DB libraries for Java

  • 项目

Overview

Store and query key-value, JSON document, graph, and columnar data in a globally distributed database with Azure Cosmos DB.

To get started with Azure Cosmos DB, see Azure Cosmos DB: Build an API app with Java and the Azure portal.

Client library

Connect to Azure Cosmos DB using the SQL API client library to work with JSON data with SQL query syntax.

Add a dependency to your Maven pom.xml file to use the Cosmos DB client library in your project.

<dependency>
    <groupId>com.microsoft.azure</groupId>
    <artifactId>azure-documentdb</artifactId>
    <version>1.12.0</version>
</dependency>

Example

Select matching JSON documents in Cosmos DB using SQL query syntax.

DocumentClient client = new DocumentClient("https://contoso.documents.azure.com:443",
                "contosoCosmosDBKey", 
                new ConnectionPolicy(),
                ConsistencyLevel.Session);

List<Document> results = client.queryDocuments("dbs/" + DATABASE_ID + "/colls/" + COLLECTION_ID,
        "SELECT * FROM myCollection WHERE myCollection.email = 'allen [at] contoso.com'",
        null)
    .getQueryIterable()
    .toList();
