本文整理了Java中com.amazonaws.services.dynamodbv2.document.DynamoDB.<init>()方法的一些代码示例，展示了DynamoDB.<init>()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。DynamoDB.<init>()方法的具体详情如下：
包路径：com.amazonaws.services.dynamodbv2.document.DynamoDB
类名称：DynamoDB
方法名：<init>

DynamoDB.<init>介绍

[英]Create a DynamoDB object that talks to the specified AWS region. The underlying service client will use all the default client configurations, including the default credentials provider chain. See AmazonDynamoDBClient#AmazonDynamoDBClient() for more information.

If you need more control over the client configuration, use DynamoDB#DynamoDB(AmazonDynamoDB) instead.
[中]创建与指定AWS区域对话的DynamoDB对象。基础服务客户端将使用所有默认客户端配置，包括默认凭据提供程序链。有关更多信息，请参见AmazondynamodClient#AmazondynamodClient（）。
如果您需要对客户端配置进行更多控制，请改用DynamoDB#DynamoDB（AmazonDynamoDB）。
