Java - copy JPG while preserving all file attributes

What is the best way to move/copy file while maintaining all its attributes (Date created, Date开发者_运维问答, etc)?

Thank you

If you are using Java 7, use java.nio.file.Files.copy(Path source, Path target, CopyOption... options)

Use the COPY_ATTRIBUTES option to maintain the last modified time:

COPY_ATTRIBUTES Attempts to copy the file attributes associated with this file to the target file. The exact file attributes that are copied is platform and file system dependent and therefore unspecified. Minimally, the last-modified-time is copied to the target file if supported by both the source and target file store. Copying of file timestamps may result in precision loss.

Emphasis added

For Java 6 and earlier, Apache commons has a function to copy files

    org.apache.commons.io.FileUtils.copyFile(File srcFile, File destFile,
boolean preserveFileDate)

Note the comments

Setting preserveFileDate to true tries to preserve the file's last modified date/times using File.setLastModified(long), however it is not guaranteed that the operation will succeed. If the modification operation fails, no indication is provided.

This will only try to preserve the modified date, and not other file attributes.

Otherwise, you will have to use Runtime.exec or something similar to run an external process.
