Java删除svn文件

我是靠谱客的博主干净玉米，最近开发中收集的这篇文章主要介绍Java删除svn文件，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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
	}

	/**
	 * 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");

	}
}

测试结果如下:


...
