Question

我正在尝试连接 Azure Cosmos 并尝试检索数据，但由于以下问题（编译时间）而失败。

使用 IntelliJ maven 运行上述项目文件时，Java 代码出现以下错误

java：com.azure.cosmos 包不存在

它应该成功运行，没有错误。

我同意你的观点，必须安装并重新加载特定 SDK 支持的所有模块才能与 Azure Cosmos DB 一起使用。

我正在尝试连接 Azure Cosmos 并尝试检索数据，但由于以下问题（编译时间）而失败。

下面是连接 Azure Cosmos DB 并从 Cosmos DB 检索数据的另一种方法。它使用

query

检索数据，如下面的输出所示。确保某些软件包及其版本在

pom.xml

中是否可用。

public static void main(String[] args) {
        CosmosClientBuilder clientBuilder = new CosmosClientBuilder()
                .endpoint(ENDPOINT)
                .key(KEY);

        CosmosClient cosmosClient = clientBuilder.buildClient();

        CosmosDatabase cosmosDatabase = cosmosClient.getDatabase(DATABASE_NAME);
        CosmosContainer cosmosContainer = cosmosDatabase.getContainer(CONTAINER_NAME);

        String query = "SELECT * FROM c"; 

        CosmosQueryRequestOptions options = new CosmosQueryRequestOptions();
        options.setQueryMetricsEnabled(true);

        cosmosContainer.queryItems(query, options, CosmosItemProperties.class)
                .byPage()
                .flatMap(cosmosItemFeedResponse -> cosmosItemFeedResponse.getResults().stream())
                .forEach(cosmosItemProperties -> {
                    System.out.println(cosmosItemProperties.toJson());
                });

        cosmosClient.close();
    }

输出：

{
    "id": "1",
    "name": "Sai",
    "age": 10,
    "class": "7th",
},
{
    "id": "2",
    "name": "Pavan",
    "age": 15,
    "class": "10th",
},
{
    "id": "3",
    "name": "Balaji",
    "age": 13,
    "class": "8th",
}
