我們有 Spring Boot 2 應用程式，并且有這樣一個任務 - 我們之前保存了 AWS S3 連接詳細資訊（存盤桶、路徑、訪問、秘密），我們需要在運行中創建 AWS S3 客戶端，只是為了測驗與給定細節的聯系。
我想@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)需要那個bean，但是如何動態設定這些連接細節？
也許有更好的方法，任何意見/解決方案表示贊賞，謝謝！
uj5u.com熱心網友回復：
我們可以通過傳遞 AccessKeyId、SecretAccessKey 和 Region 來動態創建 AWS S3 客戶端。這是解決方案。

return AmazonS3ClientBuilder
.standard()
.withCredentials(new AWSStaticCredentialsProvider(basicAWSCredentials))
.withRegion(region)
.build();
}

final S3Object s3Object = amazonS3.getObject(getObjectRequest);
final S3ObjectInputStream objectContent = s3Object.getObjectContent();
