How to disable the Spring boot logo banner at startup

There are mainly 3 ways to disable the spring boot logo banner at startup.

---

1- Pro-grammatically

SpringBootDemoApplication.java

package in.tecmentor;
import org.springframework.boot.Banner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringBootDemoApplication {
	
	public static void main(String[] args) {
		SpringApplication springApp = new SpringApplication(SpringBootDemoApplication.class);
		springApp.setBannerMode(Banner.Mode.OFF);
		springApp.run(args);
	}
}

Note-
There are 3 possible Banner.Mode availables:
OFF – Disable printing spring boot startup banner from console and log files.
CONSOLE – Print the spring boot startup banner only to console.
LOG – Print the spring boot startup banner only to the log file.

2- Using properties file

3- Using command line arguments
