java:使用vfs s3插件在Amazon S3中使用服务器端加密 [英] java : Use Server-Side Encryption in Amazon S3 using vfs s3 plugin
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();
}
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 SSECustomerKey How 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< a href =https://github.com/abashev/vfs-s3/blob/branch-2.3.x/src/main/java/com/intridea/io/vfs/provider/s3/S3FileSystemConfigBuilder.java = nofollow的> https://github.com/abashev/vfs-s3/blob/branch-2.3.x/src/main/java/com/intridea/io/vfs/provider/s3/S3FileSystemConfigBuilder.java 一>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);
