技巧：使用Java把文件/目录压缩成ZIP包

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();
   }
 }
}
