Java用ZIP进行多文件保存

Java里面的内置的ZIP文件压缩流具有很强的功能，能进行ZIP的压缩请求，下面我们来看利用ZIP流实现对文件的压缩和读取

package com.bird.thinking; import java.io.BufferedOutputStream; import java.io.BufferedReader; import java.io.FileOutputStream; import java.io.FileReader; import java.util.Enumeration; import java.util.zip.Adler32; import java.util.zip.CheckedOutputStream; import java.util.zip.ZipEntry; import java.util.zip.ZipFile; import java.util.zip.ZipOutputStream; /** * @use 用ZIP进行多文件保存 * @author Bird * */ public class ZipCompress { public static void creatIndex() throws Exception{//构建压缩文件 FileOutputStream f = new FileOutputStream("d://bird.zip");//构建文件输出流 CheckedOutputStream csum = new CheckedOutputStream(f,new Adler32());//计算和校验文件Adler32()比较快一点 ZipOutputStream zos = new ZipOutputStream(csum);//压缩文件输出流 BufferedOutputStream out = new BufferedOutputStream(zos);//构建缓冲区 zos.setComment("A Test of java Zipping");//添加注释 BufferedReader in = new BufferedReader(new FileReader("d://book.xml"));//读取磁盘的一个文件 zos.putNextEntry(new ZipEntry("book.xml"));//设置压缩包里面的内容 int c ; while((c = in.read()) != -1){ out.write(c); } in.close(); out.flush(); out.close(); } public static void readIndex() throws Exception{//读取ZIP文件 ZipFile zf = new ZipFile("d://bird.zip"); Enumeration<? extends ZipEntry> e = zf.entries(); while(e.hasMoreElements()){ ZipEntry ze2 = (ZipEntry)e.nextElement(); System.out.println(ze2.getName()); } } public static void main(String[] args) throws Exception{ readIndex(); } }
