現在很多公司采用SVN開發，其版本管理的確很不錯.
但是有一點很讓人鬱悶，就是源代碼的.svn文件會很多，而且當Java源碼代或者配置文件改變多次時，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文件去掉，可以自己寫個程序去刪除.svn目錄下的所有文件.方便又時用,我這裡采用的是commons-io.jar 裡的 DirectoryWalker,看到名稱就能理解“目錄散步”。
廢話不說瞭，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 {
//這裡可以設置斷點，比如當你找到某個類的時候，停止遍歷,默認繼續
return false;
}
@Override
protected void handleDirectoryStart(File directory, int depth,
Collection results) throws IOException {
// System.out.println(“****開始處理:”+directory.getName()+”deep:”+depth+”results:”+results.toString());
}
@Override
protected void handleDirectoryEnd(File directory, int depth,
Collection results) throws IOException {
// System.out.println(“****結束處理:”+directory.getName()+”deep:”+depth+”results:”+results.toString());
}
@Override
protected void handleRestricted(File directory, int depth,
Collection results) throws IOException {
System.out.println(“****受限制目錄:”+directory.getName()+”deep:”+depth+”results:”+results.toString());
}
/**
* 是否處理某個目錄.返回false 不處理
*
* @see 這裡直接刪除.svn.然後不處理.
*/
@Override
protected boolean handleDirectory(File directory, int depth,
Collection results) {
// delete svn directories and then skip
if (“.svn”.equals(directory.getName())) {
deleteDirectory(directory,results);
return false;
} else {
results.add(directory);//刪除.svn,還有哪些文件夾
return true;
}
}
/**
* 刪除文件，並把文件加到刪除列表中
*/
@Override
protected void handleFile(File file, int depth, Collection results) {
// delete file and add to list of deleted
//file.delete();
//results.add(file);
//刪除.svn文件後，還有哪些文件
}
/**
* 刪除目錄及目錄下的文件夾和文件
* @param directory
* @param results
*/
private void deleteDirectory(File directory,Collection results){
if(directory.isDirectory()){
File[] list = directory.listFiles();
for(File file:list){
deleteDirectory(file,results);
}
}
Log(directory.delete(),directory);
results.add(directory);//刪除文件
}
/**
* 刪除文件或者目錄失敗日志
* @param flag
*/
private void Log(boolean flag,File directory){
if(!flag){
System.err.println(“刪除文件失敗:”+directory.getAbsolutePath());
}else{
System.out.println(“delete:”+directory.getAbsolutePath());
}
}
}
測試代碼如下:
package com.ycl.filter.FileCleaner;
import java.io.File;
import java.io.IOException;
import java.util.List;
public class TestFileCleaner {
/**
* @param args
* @throws IOException
*/
public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub
FileCleaner cleaner = new FileCleaner();
File startDirectory = new File(“D:\workspace\branches\pamirsshop_branches_8-30”);
List<File> list = cleaner.clean(startDirectory);
for(File file:list){
// System.out.println(“file:”+file.getAbsolutePath());
}
System.out.println(“共處理”+list.size()+”個文件”);
}
}
測試結果如下:
…

記得我剛碰到svn的這個問題的時候，也是到處找工具，有沒有啥工具可以去掉.svn的，現在想想，自己是程序員，遇到問題，自己開發一個不就完瞭嘛，實用又方便.
