java - 无法执行 HTTP 请求

Question

我正在尝试使用 java sdk 获取附加到用户的 aws ec2 实例和 s3 存储桶的列表。我的主要程序类是

`

package com.aws.demo;

import java.util.List;




import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import com.amazonaws.auth.AWSStaticCredentialsProvider;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.ec2.AmazonEC2;
import com.amazonaws.services.ec2.AmazonEC2ClientBuilder;
import com.amazonaws.services.ec2.model.Image;
import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.AmazonS3ClientBuilder;
import com.amazonaws.services.s3.model.Bucket;

@SpringBootApplication()
public class AwsApplication {

    public static void main(String[] args) {
        SpringApplication.run(AwsApplication.class, args);
        
        final String aws_access_key_id = ""; // deleted for security reasons
        final String aws_secret_access_key = ""; // deleted for security reasons
                
        
        BasicAWSCredentials awsCreds = new BasicAWSCredentials(aws_access_key_id, aws_secret_access_key);
        
        try {           AmazonS3 s3 = AmazonS3ClientBuilder.standard().withCredentials(new AWSStaticCredentialsProvider(awsCreds))                  .withRegion("us-east-1")
                    .build();           
            List<Bucket> buckets = s3.listBuckets();
            
            buckets.stream().forEach(bucket ->{
                System.out.println("Bucket Name : "+ bucket.getName()+", Bucket Owner : "+bucket.getOwner().getDisplayName()
                +", Bucket Creation Date: "+ bucket.getCreationDate());
            });
            
            AmazonEC2 amazonEC2 = AmazonEC2ClientBuilder
                    .standard()
                    .withCredentials(new AWSStaticCredentialsProvider(awsCreds))
                    .withRegion("us-east-1")
                    .build();
            List<Image> listEc2s = amazonEC2.describeImages().getImages();
            listEc2s.stream().forEach(image->{
                System.out.println("Image id : "+image.getImageId()+"Image owner : "+image.getImageOwnerAlias());
            });
                    System.out.println("Image list"+amazonEC2.describeImages().getImages());
        }
        catch (Exception e) {
            System.out.println(e.getMessage());
            System.out.println(e.getStackTrace().toString());
        }
            
        
        
    }
    
    

}

`s3 存储桶返回存储桶列表的响应，但 ec2 实例的响应抛出以下错误

无法执行 HTTP 请求:javax.xml.stream.XMLStreamException:ParseError at [row,col]:[29070,4] 消息:连接重置

我的pom.xml文件是

`请问我该怎么做才能返回正确的响应，即附加到我的 aws 帐户的 ec2 实例列表

Answer 1

我已经解决了。我使用 AmazonEC2AsyncClientBuilder 而不是 AmazonEC2ClientBuilder
