JAVA彻底解决获取空格路径有关问题

ReadProperties read = new ReadProperties("db");
		double currentVersion = Double.valueOf(read.readProperties("Version"));
		if (version <= currentVersion) {
			String path = Thread.currentThread().getContextClassLoader()
					.getResource("").toString();//获取更目录地址
			path = path.substring(path.indexOf("/") + 1, path.length()) + "pda";
			try {
				path = URLDecoder.decode(path, "utf-8");
			} catch (UnsupportedEncodingException e) {
				e.printStackTrace();
			}// 关键啊 ！主要转换文件地址，避免空格问题
			System.out.println(path);
