包路径：org.apache.commons.io.FileUtils
类名称：FileUtils
方法名：iterateFiles

FileUtils.iterateFiles介绍

[英]Allows iteration over the files in given directory (and optionally its subdirectories).

All files found are filtered by an IOFileFilter. This method is based on #listFiles(File,IOFileFilter,IOFileFilter), which supports Iterable ('foreach' loop).
[中]允许对给定目录（以及可选的子目录）中的文件进行迭代。
找到的所有文件都由IOFileFilter筛选。此方法基于#listFiles（File，IOFileFilter，IOFileFilter），它支持Iterable（'foreach'循环）。
