springboot之banner

springboot在正常启动的时候默认打印的如下：

源码如下：

class springbootbanner implements banner {

    private static final string[] banner = { "",
            "  .   ____          _            __ _ _",
            " /\\\\ / ___'_ __ _ _(_)_ __  __ _ \\ \\ \\ \\",
            "( ( )\\___ | '_ | '_| | '_ \\/ _` | \\ \\ \\ \\",
            " \\\\/  ___)| |_)| | | | | || (_| |  ) ) ) )",
            "  '  |____| .__|_| |_|_| |_\\__, | / / / /",
            " =========|_|==============|___/=/_/_/_/" };

    private static final string spring_boot = " :: spring boot :: ";

    private static final int strap_line_size = 42;

    @override
    public void printbanner(environment environment, class<?> sourceclass,
            printstream printstream) {
        for (string line : banner) {
            printstream.println(line);
        }
        string version = springbootversion.getversion();
        version = (version != null) ? " (v" + version + ")" : "";
        stringbuilder padding = new stringbuilder();
        while (padding.length() < strap_line_size
                - (version.length() + spring_boot.length())) {
            padding.append(" ");
        }

        printstream.println(ansioutput.tostring(ansicolor.green, spring_boot,
                ansicolor.default, padding.tostring(), ansistyle.faint, version));
        printstream.println();
    }

}

对于banner的输出可以做如下修改，代码如下：

banner.txt

                   _ooooo_
                  o8888888o
                  88" . "88
                  (| -_- |)
                  o\  =  /o
               ____/`---'\____
             .'  \\|     |//  `.
            /  \\|||  :  |||//  \
           /  _||||| -:- |||||-  \
           |   | \\\  -  /// |   |
           | \_|  ''\---/''  |   |
           \  .-\__  `-`  ___/-. /
         ___`. .'  /--.--\  `. . __

application.yml

spring:
  banner:
    charset: utf-8
    location: banner.txt

application

@springbootapplication
public class application {
    public static void main(string[] args) {
//        springapplication application = new springapplication();
//        application.setbannermode(banner.mode.off);
//        application.run(application.class, args);
        springapplication.run(application.class, args);

    }
}

程序启动后如下：

更高级的操作，后续再进行研究
