JAVA文件压缩

最近工作中用到了文件压缩的功能，整理了一下。文件压缩的实现，可用JDK自带的 java.util.zip.功能，但是压缩时中文会有乱码，用org.apache.tools.zip.下的jar包可解决乱码问题，也可以修改JDK中的jar包，来决绝乱码问题。

文件压缩和解压代码：

package cn.lsh.test;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.Enumeration;

import org.apache.tools.ant.taskdefs.Mkdir;
import org.apache.tools.zip.ZipEntry;
import org.apache.tools.zip.ZipFile;
import org.apache.tools.zip.ZipOutputStream;

public class FileUtil {
    //文件压缩
    public static void zipFiles(String zipFile,String path, File... srcFiles) throws IOException{
        ZipOutputStream zos = new ZipOutputStream(new FileOutputStream(zipFile));
        FileUtil.zipFiles(zos, path, srcFiles);
        zos.close();
        System.out.println("*********压缩完毕***********");
    }
    public static void zipFiles(ZipOutputStream zos,String path,File... srcFiles){
        path = path.replaceAll("\\*", "/");
        if(!path.endsWith("/")){
            path +="/";
        }
        byte[] buf = new byte[1024];
        try {
            for(int i = 0; i < srcFiles.length; i++){
                if(srcFiles[i].isDirectory()){
                    File[] files = srcFiles[i].listFiles();

                        srcPath +="/";
                    }
                    zos.putNextEntry(new ZipEntry(srcPath+path));
                    zipFiles(zos, srcPath+path, files);
                }else{
