技巧:使用Java把文件/目录压缩成ZIP包

来源:岁月联盟 编辑:zhuzhu 时间:2007-07-10

使用java自带的类 java.util.zip进行文件/目录的压缩的话,有一点不足,不支持中文的文件/目录命名,如果有中文名,那么打包就会失败。在Ant.jar类库中也有zip类,引入 org.apache.tools.zip.*,能够解决不支持中文文件目录的问题,同时,Ant的获得途径也比较多,一般的应用服务器中有这个包,如果没有去下载个tomcat5.X,里面也有ant.jar,可以使用。

例子如下:

import java.io.File;import org.apache.tools.zip.ZipOutputStream;import java.io.FileInputStream;import java.io.FileOutputStream;public class CompressBook {        public CompressBook() {            }public void zip(String inputFileName) throws Exception {         String zipFileName="c://test.zip";//打包后文件名字    System.out.println(zipFileName);    zip(zipFileName, new File(inputFileName));          } private void zip(String zipFileName, File inputFile) throws Exception {   ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipFileName));   zip(out, inputFile, "");   System.out.println("zip done");   out.close(); } private void zip(ZipOutputStream out, File f, String base) throws Exception {   if (f.isDirectory()) {     File[] fl = f.listFiles();     out.putNextEntry(new org.apache.tools.zip.ZipEntry(base + "/"));     base = base.length() == 0 ? "" : base + "/";     for (int i = 0; i < fl.length; i++) {       zip(out, fl[i], base + fl[i].getName());     }   }   else {     out.putNextEntry(new org.apache.tools.zip.ZipEntry(base));     FileInputStream in = new FileInputStream(f);     int b;     System.out.println(base);     while ( (b = in.read()) != -1) {       out.write(b);     }     in.close();   } }}
