代码如下:

/**
     * 对zip文件进行解压解压
     * @param frompath 源文件路径
     * @param topath 解压后的文件路径
     * @throws IOException
     */
    public void ZipDecompress(String frompath,String topath) throws IOException
    {
        ZipFile zf=new ZipFile(new File(frompath));
        InputStream inputStream;
        Enumeration en=zf.getEntries();
        while(en.hasMoreElements())
        {
            ZipEntry zn=(ZipEntry) en.nextElement();
            if(!zn.isDirectory())
            {
                inputStream=zf.getInputStream(zn);
                File f=new File(topath+zn.getName());
                File file=f.getParentFile();
                file.mkdirs();
                System.out.println(zn.getName()+"---"+zn.getSize());

                FileOutputStream outputStream=new FileOutputStream(topath+zn.getName());
                int len=0;
                byte bufer[]=new byte[1024];
                while(-1!=(len=inputStream.read(bufer)))
                {
                    outputStream.write(bufer, 0, len);
                }
                outputStream.close();
            }
        }
    }
