 :: Spring Boot ::        (v2.0.3.RELEASE)

We can disable the spring banner in various ways using banner-mode. Banner mode comes in three options.

console: Print the banner to System.out.

log: Print the banner to log file.

off: Disable printing off the banner.

1. Using Properties and YAML file

Set the property in the application.properties inside the resources folder of the spring boot project.

spring.main.banner-mode=off

Set the property in the application.yaml.

spring:
  main:
    banner-mode: 'off'

2. Programmatic Configuration

Spring boot provide an option to disable the banner programatically.

You can disable the banner by setting the properties in Map.

package com.walking.techie;

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;

import java.util.HashMap;
import java.util.Map;

@SpringBootApplication
public class HelloWorldApplication {

  public static void main(String[] args) {
    Map<String, Object> props = new HashMap<>();
    props.put("spring.main.banner-mode", "off");
    
    new SpringApplicationBuilder()
            .sources(HelloWorldApplication.class)
            .properties(props)
            .run(args);
  }
}

Or You can use setBannerMode method of SpringApplication class.

package com.walking.techie;

import org.springframework.boot.Banner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class HelloWorldApplication {

  public static void main(String[] args) {
    SpringApplication app = new SpringApplication(HelloWorldApplication.class);
    app.setBannerMode(Banner.Mode.OFF);
    app.run(args);
  }
}

4. Command Line

We can change the banner mode from terminal. When packaging and running our application as jar. We can set the spring.main.banner-mode argument with java command.

java -jar hello-world-1.0.jar --spring.main.banner-mode=off

Or With the equvalent syntax:

java -jar  -Dspring.main.banner-mode=off hello-world-1.0.jar
