目标：更改控制台打印的图案

1、在SpringBoot 项目的resource目录下创建banner.txt文件，在项目初始化时，会去加载资源，banner.txt文件的内容作为一个字符数组传入并打印到控制台。

private Banner printBanner(ConfigurableEnvironment environment) {
    if (this.bannerMode == Mode.OFF) {
        return null;
    } else {
        ResourceLoader resourceLoader = this.resourceLoader != null ? this.resourceLoader : new DefaultResourceLoader(this.getClassLoader());
        SpringApplicationBannerPrinter bannerPrinter = new SpringApplicationBannerPrinter((ResourceLoader)resourceLoader, this.banner);
        return this.bannerMode == Mode.LOG ? bannerPrinter.print(environment, this.mainApplicationClass, logger) : bannerPrinter.print(environment, this.mainApplicationClass, System.out);
    }
}

2、简单的文字图案可以到文本转Ascll自定义。

3、我本人使用的是佛祖图案。

4、效果如下：
