不推荐使用的AmazonDynamoDBClient的替代方案是什么？

使用DynamoDB表类扫描: -

private static void findProductsForPriceLessThanZero() {

        Table table = dynamoDB.getTable(tableName);

        Map expressionAttributeValues = new HashMap();
        expressionAttributeValues.put(":pr", 100);

        ItemCollection 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 iterator = items.iterator();
        while (iterator.hasNext()) {
            System.out.println(iterator.next().toJSONPretty());
        }    
    }
