apache ant进行zip解压缩操作示例分享

需要导入ant.jar包，apache网站（http://ant.apache.org/bindownload.cgi）下载即可。

复制代码 代码如下:

   throw new RuntimeException("目标文件无法创建!!!");

  BufferedOutputStream bos = null;

  FileOutputStream out = null;

  ZipOutputStream zOut = null;

  try {

   // 將文件輸出ZIP输出流接起来

   zOut = new ZipOutputStream(bos);

   zip(zOut, inputFile, inputFile.getName());

   CloseIoUtil.closeAll(zOut, bos, out);

  } catch (Exception e) {

   e.printStackTrace();

  }

 }

  try {

   // 如果文件句柄是目录

   if (file.isDirectory()) {

    // 获取目录下的文件

    // 建立ZIP条目

    zOut.putNextEntry(new ZipEntry(base + "/"));

    if (listFiles != null && listFiles.length > 0)

     // 遍历目录下文件

     for (File f : listFiles)

      // 递归进入本方法

      zip(zOut, f, base + f.getName());

   }

   // 如果文件句柄是文件

   else {

     base = file.getName();

    }

    // 填入文件句柄

    zOut.putNextEntry(new ZipEntry(base));

    // 开始压缩

    // 从文件入流读,写入ZIP 出流

    writeFile(zOut, file);

   }

  } catch (Exception e) {

   e.printStackTrace();

  }

 }

   zOut.write(buff, 0, len);

  zOut.flush();

  CloseIoUtil.closeAll(bis, in);

 }
