JAVA 解决获取空格路径问题

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);
