在Spring Boot Banner

Question

我想在Spring Boot Application中自定义spring boot banner。我想在我的横幅中显示自定义变量。

class AppProfile {

    String title;
    String version;

    //getter-setter and all other stafs
    ......................
    ......................
    ......................

}

如何在Spring Boot Banner中显示标题，版本？

Answer 1

这是一种方式：

@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通过在应用程序中添加banner.txt文件来提供覆盖banner的功能。将您的自定义徽标横幅文本添加到/src/main/resources/banner.txt文件。

下面是生成横幅文本的不错工具。
