Getting Error: " the constructor AmazonKinesisFirehoseClient(AWSCredentials) is deprecated"

Question

我正在尝试将一些数据放入我的 AWS Firehose Stream，但遇到了一些困难。我还收到一条错误消息，指出无法找到我的流名称，即使它确实存在于该名称下。我还尝试了另一个活动流，但遇到了同样的问题。我不确定这个错误是否与我在构造函数被弃用时遇到的错误有关。

Firehose project-stream not found under account xxxxxxxxxxx. (Service: AmazonKinesisFirehose; Status Code: 400; Error Code: ResourceNotFoundException; Request ID: xxxxxxxxxxxxxxxxxxxxxx

在第一次尝试捕获后尝试创建 "firehoseClient," 时出现以下错误：

the constructor AmazonKinesisFirehoseClient(AWSCredentials) is deprecated

我试图查看 AWS 的 API，但找不到有效的构造函数。

使用静态 builder() 方法代替已弃用的构造函数。

javadoc 文档建议使用这种方法而不是使用已弃用的构造函数：

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