类名称：FileUtils
方法名：copyFileToDirectory

FileUtils.copyFileToDirectory介绍

[英]Copies a file to a directory preserving the file date.

This method copies the contents of the specified source file to a file of the same name in the specified destination directory. The destination directory is created if it does not exist. If the destination file exists, then this method will overwrite it.

Note: This method 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.
[中]将文件复制到保留文件日期的目录。
此方法将指定源文件的内容复制到指定目标目录中同名的文件中。如果目标目录不存在，则创建该目录。如果目标文件存在，则此方法将覆盖它。
注意：此方法尝试使用file#setlastmedited（long）保留文件的上次修改日期/时间，但不能保证操作会成功。如果修改操作失败，则不提供任何指示。
