java：使用vfs s3插件在Amazon S3中使用服务器端加密

本文介绍了java：使用vfs s3插件在Amazon S3中使用服务器端加密的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 为了在S3中复制文件，我使用 vfs-s3-2.2.1.jar 我在 com.intridea下找到 S3FileObject 类.io.vfs.provider.s3 包。 我在其中使用 public void copyFrom（最终FileObject文件，最终FileSelector选择器）复制文件的方法。 在这个方法中，我找到了以下代码：For copying file in S3, I am using vfs-s3-2.2.1.jar I found S3FileObject class under com.intridea.io.vfs.provider.s3 package.In which I am using public void copyFrom(final FileObject file, final FileSelector selector) method for copy file.In this method I found following code :try { if (srcFile.getType().hasChildren()) { destFile.createFolder(); // do server side copy if both source and dest are in S3 and using same credentials } else if (srcFile instanceof S3FileObject) { S3FileObject s3SrcFile = (S3FileObject)srcFile; String srcBucketName = s3SrcFile.getBucket().getName(); String srcFileName = s3SrcFile.getS3Key(); String destBucketName = destFile.getBucket().getName(); String destFileName = destFile.getS3Key(); CopyObjectRequest copy = new CopyObjectRequest( srcBucketName, srcFileName, destBucketName, destFileName); if (srcFile.getType() == FileType.FILE && getServerSideEncryption()) { ObjectMetadata meta = s3SrcFile.getObjectMetadata(); meta.setSSEAlgorithm(AES_256_SERVER_SIDE_ENCRYPTION); copy.setNewObjectMetadata(meta); } getService().copyObject(copy); } else if (srcFile.getType().hasContent() && srcFile.getURL().getProtocol().equals("file")) { // do direct upload from file to avoid overhead of making a copy of the file try { File localFile = new File(srcFile.getURL().toURI()); destFile.upload(localFile); } catch (URISyntaxException e) { // couldn't convert URL to URI, but should still be able to do the slower way super.copyFrom(file, selector); } } else { super.copyFrom(file, selector); }} catch (IOException e) { throw new FileSystemException("vfs.provider/copy-file.error", new Object[]{srcFile, destFile}, e);} catch (AmazonClientException e) { throw new FileSystemException("vfs.provider/copy-file.error", new Object[]{srcFile, destFile}, e);} finally { destFile.close();} 在官方参考中它使用这些方法 withSourceSSECustomerKey(sseKey)withDestinationSSECustomerKey(newSseKey); vfs-s3-2.2.1的 copyFrom 方法.jar S3FileObject 我找不到任何方法来设置 SSECustomerKey 如何实现相同的目标。 感谢您查看此处。In copyFrom method of vfs-s3-2.2.1.jar S3FileObject I can't find any method to set SSECustomerKeyHow can I achieve the same.Thanks for looking here.推荐答案我没有测试，但我快速查看了lib /代码 - 在 https://github.com/abashev/vfs-s3/blob/branch-2.3.x/src/main/java/com/intridea/io/vfs/provider/s3/S3FileSystemConfigBuilder.java 有一种设置服务器端加密的方法I did not test but I look at the lib/code quickly - in https://github.com/abashev/vfs-s3/blob/branch-2.3.x/src/main/java/com/intridea/io/vfs/provider/s3/S3FileSystemConfigBuilder.java there is a method to set the server-side encryption/** * use server-side encryption. * * @param opts The FileSystemOptions. * @param serverSideEncryption true if server-side encryption should be used. */public void setServerSideEncryption(FileSystemOptions opts, boolean serverSideEncryption){ setParam(opts, SERVER_SIDE_ENCRYPTION, serverSideEncryption);}所以在你调用 copyFrom之前你可以做什么so before you're calling the copyFrom you can do S3FileSystemConfigBuilder.getInstance().setServerSideEncryption( S3FileSystemConfigBuilder.getInstance().getFileSystem().getFileSystemOptions(), true); 这篇关于java：使用vfs s3插件在Amazon S3中使用服务器端加密的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
