使用Java AWS S3 1.9.8访问StorageGRID Webscale

Question

我正在尝试使用aws-java-sdk使用java连接到我们的StorageGRID Webscale系统，并且收到以下错误：

我对aws的maven依赖看起来像这样：

    <dependency>
        <groupId>com.amazonaws</groupId>
        <artifactId>aws-java-sdk</artifactId>
        <version>1.9.8</version>
    </dependency>

我正在使用的代码是这样的：

import com.amazonaws.auth.profile.ProfileCredentialsProvider;
import com.amazonaws.services.s3.AmazonS3Client;
import com.amazonaws.services.s3.S3ClientOptions;
import com.amazonaws.services.s3.model.Bucket;
import com.amazonaws.services.s3.model.Owner;

public class Controller {
public static void main(String[] args) {
    final String profile = "default";
    final String address = "https://my_ip_address:443";

    // use path-style access to avoid issues with DNS-incompatible bucket names
    final S3ClientOptions options = new S3ClientOptions();
    options.setPathStyleAccess(true);

    // will load credentials from ~/.aws/credentials
    final AmazonS3Client s3 = new AmazonS3Client(new ProfileCredentialsProvider(profile));
    s3.setEndpoint(address);
    s3.setS3ClientOptions(options);

    Owner owner = s3.getS3AccountOwner();
    System.out.println("Owner: " + owner.getId());
    for (Bucket b : s3.listBuckets()) {
        System.out.println("Bucket: " + b);
    }
}
}

我按照本博客中的说明操作：

我似乎无法克服这个错误。有任何想法吗？

这里的问题是我将我的代码指向错误的服务器和端口。我将'address'变量更改为：

final String address = "https://mystoragegridserver:8082";

我们还必须将证书加载到服务器上以处理SSL。
