• Java zip解压,并遍历zip中的配置文件 .cfg或.properties


    1.解析cfg或properties配置文件

    讲配置文件,读取,并封装成为map类型数据

    /**
         * 解析cfg文件
         *
         * @param cfgFile
         * @return
         */
        public static Map<String, Object> readCfg(FileInputStream cfgFile) {
            Properties prop = new Properties();
            Map<String, Object> map = new HashMap<String, Object>();
    
            try {
                // 读取cfg属性文件
                InputStream in = new BufferedInputStream(cfgFile);
                prop.load(new InputStreamReader(in, "GBK")); /// 加载属性列表
                Iterator<String> it = prop.stringPropertyNames().iterator();
                while (it.hasNext()) {
                    String key = it.next();
                    map.put(key, prop.getProperty(key).replaceAll(""", "").replaceAll(";", ""));
                }
                in.close();
            } catch (Exception e) {
                System.out.println(e);
            }
            return map;
        }

    2、文件夹遍历

     /**
         * 文件夹遍历
         * @param path
         * @throws Exception
         */
        public static void traverse(String path,String parent_id) throws Exception {
            System.out.println("path---->" + path);
            File file = new File(path);
            Map<String, Object> map = new HashMap<String, Object>();
            if (file.exists()) {
                File[] files = file.listFiles();
                if (files.length == 0) {
                    System.out.println("文件夹是空的!");
                    return;
                } else {
                    String k_id = UuidUtil.get32UUID();
    
                    for (File file2 : files) {
                        if (file2.isDirectory()) {//文件夹
    
                            traverse(file2.getAbsolutePath(),parent_id);
                            parent_id =  k_id;
                        } else if (file2.isFile()){//文件
                            if (file2.getName().endsWith(".cfg")) {
                                System.out.println("文件:" + file2.getAbsolutePath());
                                map = readCfg(new FileInputStream(file2));
                                System.out.println("-------------"+file2.getAbsolutePath()+"--start-----------");
                                map.put("path_url", getUrlPath(file2.getAbsolutePath()));
                                map.put("k_id", k_id);
                                map.put("parent_id", parent_id);
                                for (String key : map.keySet()) {
                                    System.out.println(key+"--->"+map.get(key));
                                }
                                parent_id = k_id;
                                System.out.println("-------------"+file2.getAbsolutePath()+"--end-----------");
                            }
                        }
                    }
                }
            } else {
                System.out.println("文件不存在!");
            }
        }

    3、解压zip

     /**
         * 解压zip
         *
         * @param zipFile
         * @param descDir
         * @throws Exception
         */
        public static void unZipFiles(File zipFile, String descDir) throws Exception {
            System.out.println("******************解压开始********************");
            File pathFile = new File(descDir);
            if (!pathFile.exists()) {
                pathFile.mkdirs();
            }
            ZipFile zip = new ZipFile(zipFile);
            for (Enumeration entries = zip.entries(); entries.hasMoreElements();) {
                ZipEntry entry = (ZipEntry) entries.nextElement();
                String zipEntryName = entry.getName();
                InputStream in = zip.getInputStream(entry);
                String outPath = (descDir + "/" + zipEntryName).replaceAll("\*", "/");
                // 判断路径是否存在,不存在则创建文件路径
                File file = new File(outPath.substring(0, outPath.lastIndexOf('/')));
                if (!file.exists()) {
                    file.mkdirs();
                }
                // 判断文件全路径是否为文件夹,如果是上面已经上传,不需要解压
                if (new File(outPath).isDirectory()) {
                    continue;
                }
                OutputStream out = new FileOutputStream(outPath);
                byte[] buf1 = new byte[1024];
                int len;
                while ((len = in.read(buf1)) > 0) {
                    out.write(buf1, 0, len);
                }
                if ((zipEntryName.trim().lastIndexOf("/")) == -1) {
    
                }
                in.close();
                out.close();
            }
    
            System.out.println("******************解压完毕********************");
            System.out.println("******************遍历文件夹********************");
            String parent_id = "";
            traverse(descDir,parent_id);
        }

    4,main方法

     
    private static ZipFile zf;
    private static ZipInputStream zin;
    public static void main(String[] args) throws Exception {
            try {
                File file = new File("D:\CCC.zip");
                unZipFiles(file, "D:\CCC");
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
