  以下为例子的源码,大家可以参考一下:





  /**

  package com.opensource.zip;

  import java.io.File;
  import java.io.FileInputStream;
  import java.io.FileOutputStream;
  import java.io.IOException;
  import java.util.ArrayList;
  import java.util.List;
  import java.util.zip.ZipEntry;
  import java.util.zip.ZipOutputStream;

  /**
  * 在CSDN帖子http://community.csdn.net/EXPert/topic/3316/3316352.xml?temp=.2301905中看到
  * 关于ZIP压缩文件的问题,在该类中主要演示在ZIP压缩中可以不把文件路径压缩进去
