现在很多公司采用SVN开发,其版本管理的确很不错.
但是有一点很让人郁闷,就是源代码的.svn文件会很多,而且当Java源码代或者配置文件改变多次时,会生成很多版本,svn的大小可能是源代码的N倍.
如果想把某个目录的svn文件去掉,可以自己写个程序去删除.svn目录下的所有文件.方便又时用,我这里采用的是commons-io.jar 里的 DirectoryWalker,看到名称就能理解“目录散步”。
废话不说了,代码如下:
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("-------开始清除-------");
}
@Override
protected void handleEnd(Collection results) throws IOException {
System.out.println("-------结束清除-------");
}
@Override
protected void handleCancelled(File startDirectory, Collection results,
CancelException cancel) throws IOException {
System.out.println("-------清除异常-------");
super.handleCancelled(startDirectory, results, cancel);
}
@Override
protected boolean handleIsCancelled(File file, int depth, Collection results)
throws IOException {
//这里可以设置断点,比如当你找到某个类的时候,停止遍历,默认继续
return false;
}
@Override
protected void handleDirectoryStart(File directory, int depth,
Collection results) throws IOException {
// System.out.println("****开始处理:"+directory.getName()+"deep:"+depth+"results:"+results.toString());
}
@Override
protected void handleDirectoryEnd(File directory, int depth,
Collection results) throws IOException {
// System.out.println("****结束处理:"+directory.getName()+"deep:"+depth+"results:"+results.toString());
}
@Override
protected void handleRestricted(File directory, int depth,
Collection results) throws IOException {
System.out.println("****受限制目录:"+directory.getName()+"deep:"+depth+"results:"+results.toString());
}
/**
* 是否处理某个目录.返回false 不处理
*
* @see 这里直接删除.svn.然后不处理.
*/
@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);//删除.svn,还有哪些文件夹
return true;
}
}
/**
* 删除文件,并把文件加到删除列表中
*/
@Override
protected void handleFile(File file, int depth, Collection results) {
// delete file and add to list of deleted
//file.delete();
//results.add(file);
//删除.svn文件后,还有哪些文件
}
/**
* 删除目录及目录下的文件夹和文件
* @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);//删除文件
}
/**
Tp-Link教程 * 删除文件或者目录失败日志
* @param flag
*/
private void Log(boolean flag,File directory){
if(!flag){
System.err.println("删除文件失败:"+directory.getAbsolutePath());
}else{
System.out.println("delete:"+directory.getAbsolutePath());
}
}

测试代码如下:
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("共处理"+list.size()+"个文件");
}
}
