Question

有谁知道什么已经取代了AmazonDynamoDBClient？在文档中找不到任何内容

包 - com.amazonaws.services.dynamodbv2

    AmazonDynamoDBClient amazonDynamoDBClient = new AmazonDynamoDBClient();

Answer 1

根据API文档,构建器类(例如AmazonDynamoDBClientBuilder)应该用于创建实例.

使用构建器类的示例代码: -

我已经为DynamoDB本地创建了客户端.

DynamoDB dynamoDB = new DynamoDB(AmazonDynamoDBClientBuilder.standard().withEndpointConfiguration(new EndpointConfiguration("http://localhost:8000", "us-east-1")).build());

Table table = dynamoDB.getTable("Movies");

使用DynamoDB表类扫描: -

private static void findProductsForPriceLessThanZero() {

        Table table = dynamoDB.getTable(tableName);

        Map<String, Object> expressionAttributeValues = new HashMap<String, Object>();
        expressionAttributeValues.put(":pr", 100);

        ItemCollection<ScanOutcome> items = table.scan(
            "Price < :pr", //FilterExpression
            "Id, Title, ProductCategory, Price", //ProjectionExpression
            null, //ExpressionAttributeNames - not used in this example 
            expressionAttributeValues);

        System.out.println("Scan of " + tableName + " for items with a price less than 100.");
        Iterator<Item> iterator = items.iterator();
        while (iterator.hasNext()) {
            System.out.println(iterator.next().toJSONPretty());
        }    
    }
