Java实现多文件压缩打包的方法

本文实例讲述了Java实现多文件压缩打包的方法。分享给大家供大家参考，具体如下：

package com.biao.test;import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.InputStream;import java.io.OutputStream;import java.util.Enumeration;import java.util.zip.ZipEntry;import java.util.zip.ZipFile;import java.util.zip.ZipOutputStream;public class TestZIP {    public static void zipFiles(File[] srcfile,File zipfile){    byte[] buf=new byte[1024];    try {      //ZipOutputStream类：完成文件或文件夹的压缩      ZipOutputStream out=new ZipOutputStream(new FileOutputStream(zipfile));      for(int i=0;i<srcfile.length;i++){        FileInputStream in=new FileInputStream(srcfile[i]);        out.putNextEntry(new ZipEntry(srcfile[i].getName()));        int len;        while((len=in.read(buf))>0){          out.write(buf,0,len);        }        out.closeEntry();        in.close();      }      out.close();      System.out.println("压缩完成.");    } catch (Exception e) {      // TODO Auto-generated catch block      e.printStackTrace();    }  }    public static void unZipFiles(File zipfile,String descDir){    try {      ZipFile zf=new ZipFile(zipfile);      for(Enumeration entries=zf.entries();entries.hasMoreElements();){        ZipEntry entry=(ZipEntry) entries.nextElement();        String zipEntryName=entry.getName();        InputStream in=zf.getInputStream(entry);        OutputStream out=new FileOutputStream(descDir+zipEntryName);        byte[] buf1=new byte[1024];        int len;        while((len=in.read(buf1))>0){          out.write(buf1,0,len);        }        in.close();        out.close();        System.out.println("解压缩完成.");      }    } catch (Exception e) {      // TODO Auto-generated catch block      e.printStackTrace();    }  }    public static void main(String[] args) {    //2个源文件    File f1=new File("D:\\workspace\\flexTest\\src\\com\\biao\\test\\abc.txt");    File f2=new File("D:\\workspace\\flexTest\\src\\com\\biao\\test\\test.zip");    File[] srcfile={f1,f2};    //压缩后的文件    File zipfile=new File("D:\\workspace\\flexTest\\src\\com\\biao\\test\\biao.zip");    //TestZIP.zipFiles(srcfile, zipfile);    //需要解压缩的文件    File file=new File("D:\\workspace\\flexTest\\src\\com\\biao\\test\\biao.zip");    //解压后的目标目录    String dir="D:\\workspace\\flexTest\\src\\com\\biao\\test\\";    TestZIP.unZipFiles(file, dir);  }}
