Non-Web application in spring boot [closed]

Question

I have just started learning Spring-Boot. I have created simple Spring-Boot web-application using gradle. BUT I want a non-web application project where I can run all code from PSVM and also I have to remove tomcat dependency. I searched about it but got no example.

What is needed to make the Spring Boot application context start as a non-web application context?

Spring Boot provides some example applications: https://github.com/spring-projects/spring-boot/tree/master/spring-boot-samples. The simple command line sample would be this one: https://github.com/spring-projects/spring-boot/tree/master/spring-boot-samples/spring-boot-sample-simple

From the referenced example project, the key is for the main class to implement CommandLineRunner - here is the code from the example project:

@SpringBootApplication
public class SampleSimpleApplication implements CommandLineRunner {
    // ...

    @Override
    public void run(String... args) {
        // ...
    }

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

}
