写了个一方法，方便统一批量修改电视剧文件名：
MediaFileUtils：
package net.deniro.utils;import org.apache.commons.lang.StringUtils;import org.apache.log4j.Logger;import java.io.File;import java.util.Arrays;import java.util.List;import java.util.regex.Matcher;import java.util.regex.Pattern;/** * 媒体文件 * * @author deniro *15-2-17上午10:31 */public class MediaFileUtils {/*** 需要过滤的关键词*/private static List<String> filterKeywords = Arrays.asList(new String[]{"", "S01"});private static Logger logger = Logger.getLogger(MediaFileUtils.class);public static void main(String[] args) {recursionAndRename("E:\\tv");}/*** 遍历并重命名** @param path* @return*/public static void recursionAndRename(String path) {if (StringUtils.isEmpty(path)) {logger.error("路径为空。");return;}File f = new File(path);new MediaFileUtils().recursionFile(f);}/*** 提取集号** @return*/public static String extractNos(String str) {if (StringUtils.isEmpty(str)) return str;for (String filterKeyword : filterKeywords) {if (str.contains(filterKeyword)) {str = str.replace(filterKeyword, "");}}Pattern pattern = Pattern.compile("\\d+");Matcher matcher = pattern.matcher(str);while (matcher.find()) {return matcher.group(0);}return str;}/*** 获取文件扩展名** @param file* @return*/private static String getFileExtension(File file) {String fileName = file.getName();if (fileName.lastIndexOf(".") > 0) {return fileName.substring(fileName.lastIndexOf(".") + 1);} else {return fileName.replace(extractNos(fileName), "");}}/*** 遍历文件夹（递归）** @param f*/public void recursionFile(File f) {File[] files = f.listFiles();for (File file : files) {if (file.isDirectory()) {recursionFile(file);} else {try {String extension = getFileExtension(file);File newFile = new File(file.getParent() + "\\" + extractNos(file.getName().replace("." + extension, "")) + "." + extension);file.renameTo(newFile);} catch (Exception e) {logger.error("文件改名", e);}}}}}
单元测试：
