Question

Java字体很不稳定。

这是我目前的编码，这只是一个简单的方法，从文件中获取字体，然后返回它，但我遗漏了一些东西，我只是不知道什么......有人可以帮忙吗？

private Font createFont(){
    try {
        URL fontUrl = getClass().getClassLoader().getResource("res/Fonts/aesysmatt.ttf");
        Font mFont = Font.createFont(Font.TRUETYPE_FONT, fontUrl.openStream());
        GraphicsEnvironment.getLocalGraphicsEnvironment().registerFont(font);
        return mFont;
    } catch (FontFormatException | IOException e) {
        e.printStackTrace();
    }
    return null;
}

以下是我的错误：

嗯，我不确定我是怎么做到的，但是一旦修好了，最后就出现了错误行，希望对某人有所帮助。

    URL fontUrl = getClass().getResource("res/Fonts/aesymatt.ttf");

一定是因为它在原版上加载了classLoader，这实际上没有任何意义。
