There are multiple ways to disable spring boot banner as follows:

1. SpringBootApplication main method

@SpringBootApplication
public class SpringBootDemoApplication {

    public static void main(String[] args) throws Exception {

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

Three possible values of Banner.Mode are as follows:-

OFF     – Disable printing of the banner.
CONSOLE – Print the banner to System.out.
LOG     – Print the banner to the log file

2. application.properties

spring.main.banner-mode=off

3. application.yml

spring:
  main:
    banner-mode:"off"

4. command-line parameter

$ java -jar -Dspring.main.banner-mode=off spring-boot-app-1.0.jar

OR

$ java -jar spring-boot-app-1.0.jar --spring.main.banner-mode=off
