解压zip压缩文件，Java

    //解压
    public static void decompress(String srcPath, String destPath) throws Exception 
        File file = new File(srcPath);
        if (!file.exists()) 
            throw new RuntimeException(srcPath + "文件不存在");
        

        ZipFile zf = new ZipFile(file);
        Enumeration entries = zf.entries();
        ZipEntry entry;
        while (entries.hasMoreElements()) 
            entry = (ZipEntry) entries.nextElement();
            //非文件
            if (entry.isDirectory()) 
                String dirPath = destPath + File.separator + entry.getName();
                File dir = new File(dirPath);
                dir.mkdirs();
             else 
                //文件
                File f = new File(destPath + File.separator + entry.getName());
                if (!f.exists()) 
                    f.createNewFile();
                

                // 文件数据写入文件
                InputStream is = zf.getInputStream(entry);
                FileOutputStream fos = new FileOutputStream(f);

                int count;
                byte[] buf = new byte[1024 * 4];
                while ((count = is.read(buf)) != -1) 
                    fos.write(buf, 0, count);
                

                is.close();
                fos.close();
            
        
    

传入一个压缩文件(srcPath)，然后将压缩文件的内容（文件，目录）递归的解压到目的路径（destPath）下重建文件层次结构。
