java:使用vfs S3插件在AmazonS3中使用服务器端加密
为了在S3中复制文件,我使用的是vfs-S3-2.2.1。jar
我在com下找到了S3FileObject类。因特里迪亚。木卫一。vfs。供应商。s3包。
其中,我使用public void copyFrom(final FileObject file, final FileSelector selector)
方法复制文件。
在这个方法中,我发现了以下代码:
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();
}
In official reference it uses these method
withSourceSSECustomerKey(sseKey)
withDestinationSSECustomerKey(newSseKey);
在vfs-s3-2.2.1的copyFrom方法中。jarS3FileObject 我找不到任何方法来设置SSECustomerKey 我怎样才能达到同样的效果。 谢谢你看这里

我没有进行测试,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中有一种方法可以设置服务器端加密
因此,在调用
copyFrom
之前,您可以执行以下操作
