上传文件

下面的示例演示如何使用高级别分段上传 API (TransferManager 类) 上传对象。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.File; 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.transfer.TransferManager; import com.amazonaws.services.s3.transfer.TransferManagerBuilder; import com.amazonaws.services.s3.transfer.Upload; public class HighLevelMultipartUpload { public static void main(String[] args) throws Exception { String clientRegion = "*** Client region ***"; String bucketName = "*** Bucket name ***"; String keyName = "*** Object key ***"; String filePath = "*** Path for file to upload ***"; try { AmazonS3 s3Client = AmazonS3ClientBuilder.standard() .withRegion(clientRegion) .withCredentials(new ProfileCredentialsProvider()) .build(); TransferManager tm = TransferManagerBuilder.standard() .withS3Client(s3Client) .build(); // TransferManager processes all transfers asynchronously, // so this call returns immediately. Upload upload = tm.upload(bucketName, keyName, new File(filePath)); System.out.println("Object upload started"); // Optionally, wait for the upload to finish before continuing. upload.waitForCompletion(); System.out.println("Object upload complete"); } 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(); } } }
