Making fun with Spring ImageBanner

I believe that  most you have seen Spring ASCII logo in your console window on the Spring Boot application start up. Just in case here is an example:

But the interesting thing is that you can create such ASCII graphics easily by your own.

In Spring Boot 1.4 a new class called ImageBanner was introduced. You can play with this class in any project that has spring-boot version 1.4 or greater. So to make some fun I created a simple spring boot application using Spring Initializr and the basic usage of ImageBanner is following:

package com.wordpress.nikitapavlenko;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.ImageBanner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.core.env.Environment;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;

@SpringBootApplication
public class ImagebannerSpringApplication implements CommandLineRunner {

	@Autowired
	private Environment environment;

	public static void main(String[] args) {
		SpringApplication.run(ImagebannerSpringApplication.class, args);
	}

	@Override
	public void run(String... strings) throws Exception {
		Resource imageResource = new ClassPathResource("9gag.png");
		ImageBanner imageBanner = new ImageBanner(imageResource);
		imageBanner.printBanner(environment, getClass(), System.out);
	}
}

Just to clarify I need to mention that Spring boot initilizr creates usual mvn project with src/main/java, src/main/resources folders. The image “9gag.png” was placed to src/main/resources folder and it looks following:

The result of program execution printed that cool ASCII graphics in the console log:

It looks awesome, does not it? You can checkout the code from my github imagebanner-spring-demo or you can try to play with ImageBanner directly in browser imagebanner-demo.herokuapp.com. I created and deployed to heroku small app that can do conversion to ASCII for you.

Thanks for your attention!
