java开发AmazonS3对象存储的工具类

上两节说了文档上默认不用证书的方式操作对象，但大部分时候出于安全考虑是要用到证书认证的。下面就是对这种情况下的对象操作。
1.引入pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

2.查询存储对象的工具类，有三种方法

package com.zhanglf.aws;

import com.amazonaws.AmazonClientException;
import com.amazonaws.AmazonServiceException;

import com.amazonaws.Protocol;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.AWSStaticCredentialsProvider;

import com.amazonaws.services.s3.model.S3ObjectSummary;

public class AWSListTest extends AwsConfig {
    public void listObject(){
        AWSCredentials credentials=new BasicAWSCredentials(accessKey,secretKey);
        ClientConfiguration clientConfig=new ClientConfiguration();

        try {
            clientConfig.setProtocol(Protocol.HTTP);
            AmazonS3Client conn=new AmazonS3Client(credentials,clientConfig);
            conn.setEndpoint(ENDPOINT);

            ObjectListing objects = conn.listObjects(bucketName);
            do {
                for(S3ObjectSummary objectSummary:objects.getObjectSummaries()){
                    System.out.println(objectSummary.getKey());
                }
            } while (objects.isTruncated());
        } catch (AmazonServiceException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (AmazonClientException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

    public void listObjectWithClientBuilder(){
        AWSCredentials credentials=new BasicAWSCredentials(accessKey,secretKey);
        ClientConfiguration clientConfig=new ClientConfiguration();
        try {
            clientConfig.setProtocol(Protocol.HTTP);
            AmazonS3ClientBuilder builder=AmazonS3ClientBuilder.standard().withCredentials(new AWSStaticCredentialsProvider(credentials));
            EndpointConfiguration endpointConfiguration=new EndpointConfiguration(ENDPOINT,Regions.AP_NORTHEAST_1.getName());
            builder.setEndpointConfiguration(endpointConfiguration);

            AmazonS3 conn=builder.build();

            ListObjectsV2Request req=new ListObjectsV2Request().withBucketName(bucketName);

            ListObjectsV2Result result;
            do{
                result= conn.listObjectsV2(req);
                for(S3ObjectSummary objectSummary :result.getObjectSummaries()){

                    System.out.println(objectSummary.getKey());
                }
            }while(result.isTruncated());

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

    public void getObjectByKey(String key){
        AWSCredentials credentials=new BasicAWSCredentials(accessKey,secretKey);
        ClientConfiguration clientConfig=new ClientConfiguration();
        try {
            clientConfig.setProtocol(Protocol.HTTP);
            AmazonS3ClientBuilder builder=AmazonS3ClientBuilder.standard().withCredentials(new AWSStaticCredentialsProvider(credentials));
            EndpointConfiguration endpointConfiguration=new EndpointConfiguration(ENDPOINT,Regions.AP_NORTHEAST_1.getName());
            builder.setEndpointConfiguration(endpointConfiguration);

            AmazonS3 conn=builder.build();

            S3Object object = conn.getObject(bucketName, key);
            System.out.println(object.getKey());

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}

3.将对象上传到AWS的工具类，也有三种方法
