java压缩文件夹包含所有子文件夹以及子文件

import java.io.File;
import org.apache.tools.zip.ZipOutputStream; //这个包在ant.jar里，要到官方网下载
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.zip.ZipInputStream;
import java.util.zip.ZipEntry;


public class BuildFolderZip {
    public BuildFolderZip() {}


    /*
    * inputFileName 输入一个文件夹
    * zipFileName 输出一个压缩文件夹
    */
    public void zip(String inputFileName,String zipFileName) throws Exception {
//        String zipFileName = "D:\\test.zip"; //打包后文件名字
        System.out.println("in :"+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文件打包成功. <<<<<<");
        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(">>>>>>压缩的文件中包含:"+base+" .<<<<<<");
           while ( (b = in.read()) != -1) {
            out.write(b);
         }
         in.close();
       }
    }


//    public static void main(String [] temp){
//        CompressBook book = new CompressBook();
//        try {
//           book.zip("c:\\天使");//你要压缩的文件夹
//        }catch (Exception ex) {
//           ex.printStackTrace();
//       }
//    }

} 

这个需要一个jar包org.apache.tools.zip.ZipOutputStream; //这个包在ant.jar里，要到官方网下载或者到我共享的资源里面下载
