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();}}
