我正在尝试将我的应用程序连接到 DynamoDB。我已经按照亚马逊推荐的方式设置了一切。但我仍然一遍又一遍地遇到同样的错误:

解决办法是什么？
最佳答案
好吧，看来您需要添加:
ddbClient.setRegion(Region.getRegion(Regions.EU_WEST_1));
// Add correct Region. In my case its EU_WEST_1
在以下行之后:
AmazonDynamoDBClient ddbClient = new AmazonDynamoDBClient(credentialsProvider);
现在可以了。表已成功创建。 祝你有美好的一天，谢谢!
