/** * 创建目录 * * @param path */ public static void CreatFileDir(String path) { try { File file = new File(path); if(file.getParentFile().isDirectory()){//判断上级目录是否是目录 if(!file.exists()){ //如果文件目录不存在 file.mkdirs(); //创建文件目录 } }else{ throw new Exception("传入目录非标准目录名"); } } catch (Exception e) { e.printStackTrace(); } }
