現在很多公司采用SVN開發,其版本管理的确很不錯.
但是有一點很讓人郁悶,就是源代碼的.svn檔案會很多,而且當Java源碼代或者配置檔案改變多次時,會生成很多版本,svn的大小可能是源代碼的N倍.
如果想把某個目錄的svn檔案去掉,可以自己寫個程式去删除.svn目錄下的所有檔案.友善又時用,我這裡采用的是commons-io.jar 裡的 DirectoryWalker,看到名稱就能了解“目錄散步”。
廢話不說了,代碼如下:
- package com.ycl.filter.FileCleaner;
- import java.io.File;
- import java.io.IOException;
- import java.util.ArrayList;
- import java.util.Collection;
- import java.util.List;
- import org.apache.commons.io.DirectoryWalker;
- public class FileCleaner extends DirectoryWalker {
- public FileCleaner() {
- super();
- }
- public List<File> clean(File startDirectory) throws IOException {
- List<File> results = new ArrayList<File>();
- walk(startDirectory, results);
- return results;
- }
- @Override
- protected void handleStart(File startDirectory, Collection results)
- throws IOException {
- System.out.println("-------開始清除-------");
- }
- @Override
- protected void handleEnd(Collection results) throws IOException {
- System.out.println("-------結束清除-------");
- }
- @Override
- protected void handleCancelled(File startDirectory, Collection results,
- CancelException cancel) throws IOException {
- System.out.println("-------清除異常-------");
- super.handleCancelled(startDirectory, results, cancel);
- }
- @Override
- protected boolean handleIsCancelled(File file, int depth, Collection results)
- throws IOException {
- //這裡可以設定斷點,比如當你找到某個類的時候,停止周遊,預設繼續
- return false;
- }
- @Override

- Collection results) throws IOException {

- }

- Collection results) {
- // delete svn directories and then skip
- if (".svn".equals(directory.getName())) {
- deleteDirectory(directory,results);
- return false;
- } else {
- results.add(directory);//删除.svn,還有哪些檔案夾

- }
