Properties 使用

   try {

        private Properties prop = new Properties();

        FileReader fr = new FileReader("conf" + File.separator + "config.properties");
        BufferedReader br = new BufferedReader(fr);
        prop.load(br);
        br.close();
    } catch (FileNotFoundException e) {
        new Alert(Alert.AlertType.NONE, "未找到配置文件config.properties", new ButtonType[]{ButtonType.CLOSE}).show();
    } catch (Exception e) {
        e.printStackTrace();
    }


建议用下边这个

String conf = System.getProperty("user.home") + File.separator + "conf.properties";
FileInputStream fis = new FileInputStream(conf);
prop.load(fis);
fis.close();
