Java 将awssdk s3 v2与地面军事系统和Minio网关一起使用时出现Etag解码错误

我目前正在迁移Java代码库以供使用

我通过Minio网关与S3API交互，该网关向GCS（谷歌云存储）发送/获取对象。 同步客户端以前工作正常，但现在我无法执行简单的Put操作，例如

PutObjectRequest

，因为sdk客户端在实际接收到不同编码的哈希时，在“eTag”字段中需要MD5哈希。我宣布我的客户如下：

AwsBasicCredentials credentials=AwsBasicCredentials.create（config.getKey（），config.getSecret（））；
返回S3Client.builder（）
.endpointOverride（URI.create（config.getEndpoint（）））
.region（region.of（config.getRegion（）））
.credentialsProvider（StaticCredentialsProvider.create（凭据））
.serviceConfiguration（S3Configuration.builder（）.pathStyleAccessEnabled（true）.build（））
.build（）；

并将其与简单的Put请求一起使用，例如：

byte[]content=“这是内容”。getBytes（）；
RequestBody RequestBody=RequestBody.fromBytes（内容）；
PutObjectRequest build=PutObjectRequest.builder（）
.桶（桶）
.key（“测试文件”）
.build（）；
s3Client.putObject（build，requestBody）；

stacktrace错误如下所示：

请注意：

• 我直接在GCS上做了同样的测试，它工作得很好（GCS实际上返回了一个MD5散列），所以这似乎是一个Minio网关问题
• 我以前（使用客户端v1时）使用了“S3SignerType”覆盖
• 我已尝试将

  Aws4Signer

  或

  AwsS3V4Signer

  中的一个添加到我的客户端配置中，但未成功

环境：

• 迷你们：

• Java SDK版本：2.5.25

有什么想法吗？

它实际上是

发行版下的版本。2019-05-23T00-29-34Z

，从那以后就有了。
