本文整理了Java中org.apache.commons.io.FileUtils.copyDirectory()方法的一些代码示例，展示了FileUtils.copyDirectory()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。FileUtils.copyDirectory()方法的具体详情如下：
包路径：org.apache.commons.io.FileUtils
类名称：FileUtils
方法名：copyDirectory

FileUtils.copyDirectory介绍

[英]Copies a whole directory to a new location preserving the file dates.

This method copies the specified directory and all its child directories and files to the specified destination. The destination is the new location and name of the directory.

The destination directory is created if it does not exist. If the destination directory did exist, then this method merges the source with the destination, with the source taking precedence.

Note: This method tries to preserve the files' last modified date/times using File#setLastModified(long), however it is not guaranteed that those operations will succeed. If the modification operation fails, no indication is provided.
[中]将整个目录复制到保留文件日期的新位置。
此方法将指定目录及其所有子目录和文件复制到指定的目标。目标是目录的新位置和名称。
如果目标目录不存在，则创建该目录。如果目标目录确实存在，则此方法将源目录与目标目录合并，源目录优先。
注意：此方法尝试使用文件#setlastmedited（long）保留文件的上次修改日期/时间，但不能保证这些操作会成功。如果修改操作失败，则不提供任何指示。
