How to Create and Run a Command Line Application using Spring Boot

If you have a requirement to develop a simple application using Spring Boot that runs on the Console (Terminal) then you can follow below two easy steps to get started,

Step 1: Project Dependencies

    Go to and do not choose any dependencies and hit Generate.

    Create a Spring Boot Project using

    You only need one starter dependency i.e. 'org.springframework.boot:spring-boot-starter'

    dependencies {
        implementation 'org.springframework.boot:spring-boot-starter'
    Maven: pom.xml

Step 2: Make Application class implement CommandLineRunner

    Now all you need to do is open the Application class (one with annotation @SpringBootApplication) and make it implement CommandLineRunner.

    Next, you need to override the run() method where you add your logic for your command-line application.

    package org.code2care.demo;
    import org.springframework.boot.CommandLineRunner;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.context.ApplicationContext;
    public class DemoApplication implements CommandLineRunner {
        public static void main(String[] args) {
  , args);
            ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationConfig.xml");
            Employee employee = applicationContext.getBean("employee", Employee.class);
        public void run(String... args) throws Exception {
            System.out.println("This is it!");
