使用 AWS SDK for Java 复制对象

以下示例演示如何使用AWS SDK for Java复制 Amazon S3 中的对象。有关创建和测试有效示例的说明,请参阅测试 Amazon S3 Java 代码示例

import java.io.IOException; import com.amazonaws.AmazonServiceException; import com.amazonaws.SdkClientException; import com.amazonaws.auth.profile.ProfileCredentialsProvider; import com.amazonaws.services.s3.AmazonS3; import com.amazonaws.services.s3.AmazonS3ClientBuilder; import com.amazonaws.services.s3.model.CopyObjectRequest; public class CopyObjectSingleOperation { public static void main(String[] args) throws IOException { String clientRegion = "*** Client region ***"; String bucketName = "*** Bucket name ***"; String sourceKey = "*** Source object key *** "; String destinationKey = "*** Destination object key ***"; try { AmazonS3 s3Client = AmazonS3ClientBuilder.standard() .withCredentials(new ProfileCredentialsProvider()) .withRegion(clientRegion) .build(); // Copy the object into a new object in the same bucket. CopyObjectRequest copyObjRequest = new CopyObjectRequest(bucketName, sourceKey, bucketName, destinationKey); s3Client.copyObject(copyObjRequest); } catch(AmazonServiceException e) { // The call was transmitted successfully, but Amazon S3 couldn't process // it, so it returned an error response. e.printStackTrace(); } catch(SdkClientException e) { // Amazon S3 couldn't be contacted for a response, or the client // couldn't parse the response from Amazon S3. e.printStackTrace(); } } }
