Question

我正在尝试将一些数据放到我的AWS Firehose Stream中，但遇到了一些困难。我也收到一个错误，我的流名称无法找到，即使它肯定存在于该名称下。我也尝试了另一个活动流，我遇到了同样的问题。我不确定这个错误是否与我不赞成使用构造函数的错误有关。

在帐户xxxxxxxxxxx下找不到Firehose项目流。（服务：AmazonKinesisFirehose;状态代码：400;错误代码： ResourceNotFoundException;请求ID：xxxxxxxxxxxxxxxxxxxxxx

当我尝试创建＆＃34; firehoseClient，＆＃34;时出现以下错误在我第一次试试之后：

构造函数AmazonKinesisFirehoseClient（AWSCredentials）是弃用

我试图透过AWS＆＃39; API，但找不到有效的构造函数。

使用static builder（）方法代替不推荐使用的构造函数。

javadoc文档提出了这种方法，而不是使用弃用的构造函数：

AmazonKinesisFirehoseClient client = AmazonKinesisFirehoseClientBuilder.standard().withCredentials(new AWSStaticCredentialsProvider(awsCredentials)).build();
// You can now use the client as you normally would...
client.putRecord(xyz);

请参阅：http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/kinesisfirehose/AmazonKinesisFirehoseClient.html#AmazonKinesisFirehoseClient-com.amazonaws.auth.AWSCredentials-

得到错误：＆＃34;不推荐使用构造函数AmazonKinesisFirehoseClient（AWSCredentials）＆＃34;
