對應的代碼

    public static Properties loadConf(String file) {
        Properties pro = new Properties();
        try {
            InputStream in = pro.getClass().getResourceAsStream(file);
            pro.load(in);
            in.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return pro;

已測試ok的方法

    private static Properties loadConf(String file) {
        Properties pro = new Properties();
        try {
            pro.load(new FileInputStream(file));
        } catch (Exception e) {
            e.printStackTrace();
        }
        return pro;
    }
