Java删除svn文件
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**”。
废话不说了,代码如下:
Java代码- 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());
- }
- }
- }
复制代码 测试代码如下:
Java代码- 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");
- }
- }
复制代码 测试结果如下:
Java代码- ...
- delete:D:\workspace\branches\pamirsshop_branches_8-30\deploy\src\main\.svn
- delete:D:\workspace\branches\pamirsshop_branches_8-30\deploy\src\main\assembly\.svn\text-base\assembly.xml.svn-base
- delete:D:\workspace\branches\pamirsshop_branches_8-30\deploy\src\main\assembly\.svn\text-base
- delete:D:\workspace\branches\pamirsshop_branches_8-30\deploy\src\main\assembly\.svn\prop-base
- delete:D:\workspace\branches\pamirsshop_branches_8-30\deploy\src\main\assembly\.svn\props
- delete:D:\workspace\branches\pamirsshop_branches_8-30\deploy\src\main\assembly\.svn\tmp\text-base
- delete:D:\workspace\branches\pamirsshop_branches_8-30\deploy\src\main\assembly\.svn\tmp\prop-base
- delete:D:\workspace\branches\pamirsshop_branches_8-30\deploy\src\main\assembly\.svn\tmp\props
- delete:D:\workspace\branches\pamirsshop_branches_8-30\deploy\src\main\assembly\.svn\tmp
- delete:D:\workspace\branches\pamirsshop_branches_8-30\deploy\src\main\assembly\.svn\all-wcprops
- delete:D:\workspace\branches\pamirsshop_branches_8-30\deploy\src\main\assembly\.svn\entries
- delete:D:\workspace\branches\pamirsshop_branches_8-30\deploy\src\main\assembly\.svn
- -------结束清除-------
- 共处理3331个文件
复制代码 记得我刚碰到svn的这个问题的时候,也是到处找工具,有没有啥工具可以去掉.svn的,现在想想,自己是程序员,遇到问题,自己开发一个不就完了嘛,实用又方便. |
