In a Spring Boot application, the console startup banner is driven by a file named banner.txt. Place it under src/main/resources to replace the default Spring artwork.

Composing the Banner

The file supports plain text, ASCII art, and property placeholders using ${...} syntax. Colors are applied via ${AnsiColor.xxx} constants defined in org.springframework.boot.ansi.AnsiColor.

${AnsiColor.BRIGHT_CYAN}

       |_|
${AnsiColor.BRIGHT_WHITE}
Application: ${spring.application.name} v${application.version}
Active Profile: ${spring.profiles.active}

Available built‑in placeholders include application.version, spring.application.name, spring.profiles.active, local.date, local.time, aswell as random generators such as ${random.int}. Custom properties defined in application.properties or application.yml can also be referenced.

application.properties

app.description=Order Management Service

banner.txt

${app.description}

Banner Location

The default path is classpath:banner.txt. To use a different file, set the location:

application.yml

spring:
  banner:
    location: static/custom-banner.txt

Controlling Display

Banner mode is controlled via the enum org.springframework.boot.Banner.Mode with values OFF, CONSOLE, and LOG. The default is CONSOLE.

Disable via Configuration

application.properties

spring.main.banner-mode=off

Disable Programmatically

When launching the application, set the mode directly on the SpringApplication instance or use the builder:

new SpringApplicationBuilder(MyApplication.class)
        .bannerMode(Banner.Mode.OFF)
        .run(args);

Alternatively, set bannerMode on a SpringApplication object:

SpringApplication app = new SpringApplication(MyApplication.class);
app.setBannerMode(Banner.Mode.OFF);
app.run(args);

Programmatic Banner

For full control, implement the Banner interface and register it:

SpringApplication app = new SpringApplication(MyApplication.class);
app.setBanner((environment, sourceClass, out) -> {
    out.println("Custom programmatic banner");
});
app.run(args);
