这是一种方法：

@SpringBootApplication
public class BootApplication extends SpringBootServletInitializer {

    public static void main(final String[] args) {
        SpringApplication springApplication = new SpringApplication(BootApplication.class);
        springApplication.setBanner(new CustomBanner());
        springApplication.run(args);
    }

    private static class CustomBanner implements Banner {
        //@formatter:off
        private static final String[] BANNER = {
                "  ______          ",
                " |  ____|         ",
                " | |__ ___   ___  ",
                " |  __/ _ \\ / _ \\ ",
                " | | | (_) | (_) |",
                " |_|  \\___/ \\___/ ",
                "                  "
        };
        //@formatter:on

        private static final String SPRING_BOOT = " :: Spring Boot :: ";

        @Override
        public void printBanner(final Environment environment, final Class<?> sourceClass, final PrintStream printStream) {
            String padding = "";
            for (String line : BANNER) {
                printStream.println(line);
            }
            AppProfile appProfile = new AppProfile();
            printStream.println(AnsiOutput.toString(AnsiColor.YELLOW, appProfile.title, AnsiColor.DEFAULT, padding, AnsiStyle.FAINT,
                    appProfile.version));
            printStream.println(AnsiOutput.toString(AnsiColor.GREEN, SPRING_BOOT, AnsiColor.DEFAULT, padding, AnsiStyle.FAINT,
                    SpringBootVersion.getVersion()));
            printStream.println();
        }

    }

    private static class AppProfile {
        public String title = " :: Foo App :: ";
        public String version = "4.2.12.123";
    }
}

Spring提供了通过在应用程序中添加banner.txt文件来覆盖banner的功能。将您的自定义徽标banner文本添加到/src/main/resources/banner. txt文件。
下面是一个很酷的工具来生成横幅文本。

您可以在pom.xml中添加插件
