banner就是启动时的图标

可以在这几个网址自己定义banner

*  [http://patorjk.com/software/taag][http_patorjk.com_software_taag]
 *  [http://www.network-science.de/ascii/][http_www.network-science.de_ascii]
 *  [http://www.degraeve.com/img2txt.php][http_www.degraeve.com_img2txt.php]

在resources下新建一个banner.txt文件，我放了下面的内容

${AnsiColor.BRIGHT_RED}
    ${AnsiBackground.BRIGHT_YELLOW}
    
                                                         
                                                         
                          .                              
                        .'|                              
                       <  |                              
       ____     _____   | |            ____     _____    
      `.   \  .'    /   | | .'''-.    `.   \  .'    /    
        `.  `'    .'    | |/.'''. \     `.  `'    .'     
          '.    .'      |  /    | |       '.    .'       
          .'     `.     | |     | |       .'     `.      
        .'  .'`.   `.   | |     | |     .'  .'`.   `.    
      .'   /    `.   `. | '.    | '.  .'   /    `.   `.  
     '----'       '----''---'   '---''----'       '----'

启动时样式

![70][]

$\{AnsiColor.BRIGHT\_RED\} 设置字的颜色

$\{AnsiBackground.BRIGHT\_YELLOW\}设置背景色

可以看一下类里定义的其他的东西

若想关闭掉banner，在启动类中修改如下图所示

package com.xhx.springboot.banner;
    
    import org.springframework.boot.Banner;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class BannerApplication {
    
        public static void main(String[] args) {
    //          SpringApplication.run(BannerApplication.class, args);
            SpringApplication app = new SpringApplication(BannerApplication.class);
            app.setBannerMode(Banner.Mode.OFF);
            app.run(args);
    
        }
    }
