Why Custom Banners and Startup Customization Matter

Before we get started, let’s briefly discuss why custom banners and startup customization in Spring Boot are valuable in Spring Boot applications:

  1. Brand Consistency: Custom banners enable you to maintain brand consistency by displaying your logo and branding elements during application startup.
  2. Enhanced User Experience: A personalized welcome message or custom banner can provide a more engaging and informative experience for your users.
  3. Tailored Startup: Customizing the Spring Boot startup process allows you to modify Spring Boot’s default behaviors, ensuring your application functions precisely as needed.

Creating a Custom Banner in Spring Boot

Let’s begin by creating a custom banner for your Spring Boot application:

  • Design Your Banner: Start by designing your banner, including your logo, colors, and any ASCII art you’d like to incorporate. Ensure your design aligns with your brand identity.
  • ASCII Art Conversion: Convert your design into ASCII art. Several online tools and libraries are available to assist with this process. Optimize the size and format for the best results.
  • Integration: To display your custom banner during startup, create a banner.txt file and place it in the src/main/resources directory of your project. Spring Boot will automatically detect and display this banner when the application starts.

Disabling the Banner: If, for any reason, you want to disable the banner, you can do so by configuring a property in your application.properties or application.yml file:

Java
spring:
  main:
    banner-mode: off

Disabling the Banner: Programmatic approach

Java
@SpringBootApplication
class BootApplication {
    public static void main(String args[]) {
        SpringApplicationBuilder builder = new SpringApplicationBuilder(BootApplication.class);
        
        // Turn off the Spring Boot banner programmatic approach
        builder.bannerMode(Banner.Mode.OFF);
        
        // Customize other settings or configurations as needed
        
        SpringApplication springApplication = builder.build();
        ApplicationContext context = springApplication.run(args);
    }
}

In this code snippet, we:

  • Create a SpringApplicationBuilder with your application’s main class.
  • Turn off the Spring Boot banner using bannerMode(Banner.Mode.OFF).
  • Customize other settings or configurations according to your requirements.
