Amazon s3 に接続するために Java コードを使用しています。S3 に接続しようとするたびに、HttpHostConnection の拒否エラーが発生します。S3 では、所有者としてのすべての権限を持つバケットが 1 つしかありません。バケット内のファイルを一覧表示しようとしたり、S3 にファイルをアップロードしようとしたりするたびに、エラーが発生します。
コードは次のとおりです。
TransferManager tx = new TransferManager(credentials);
Upload upload = tx.upload("bucket.name", doc.getFileName(), new File("C:\\testing2.pdf"));
while (upload.isDone() == false) {
System.out.println(upload.getProgress().getPercentTransferred() + "%");
}
