我正在尝试检索手动上传到AWS S3 Bucket的文件(asdf.txt)。我们称之为" myBucket"。我已经设置了存储桶的权限,并且所有人都可以完全访问该文件。当我致电getObject()
时,我收到错误消息Connection timed out
。这是我的stacktrace:

这是我的代码:
public static void main(String[] args) {
AmazonS3Client s3 = new AmazonS3Client();
s3.setEndpoint("s3.amazonaws.com");
s3.setRegion(Region.getRegion(Regions.US_WEST_1));
S3Object obj = s3.getObject(new GetObjectRequest("myBucket", "asdf.txt"));
System.out.println(obj.getBucketName());
}
我也尝试了几种不同的方法。修改后的行如下所示:
s3.setEndpoint("https://myBucketName.s3.amazonaws.com");
S3Object obj = s3.getObject("myBucket", "asdf.txt");
谁能告诉我我做错了什么?
答案 0 :(得分:2)
U have to configure AmazonS3Client with following properties:
1.connectionTimeout=50000 in ms
2.maxConnections=500
3.socketTimeout=50000 in ms
4.maxErrorRetry=10
And don't use Transfermanager for upload and download
Use:
AmazonS3Client(AWSCredentials awsCredentials, ClientConfiguration clientConfiguration)
see:[properties][1]
[1]: http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/ClientConfiguration.html
答案 1 :(得分:0)
原来这是代理问题。我只需要指定代理配置并使用配置实例化客户端
AwsSyncClientBuilder builder = AmazonS3ClientBuilder.standard();
ClientConfiguration cc = new ClientConfiguration();
cc.setProxyHost("<proxyAddress>");
cc.setProxyPort(<proxyPort>);
AWSCredentialsProvider credentials = new DefaultAWSCredentialsProviderChain();
AmazonS3Client s3 = (AwsSyncClientBuilder) builder
.withClientConfiguration(cc)
.withCredentials(credentials)
.withRegion(Regions.US_EAST_1);
