Spring Boot 

package com.logicbig.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

@SpringBootApplication
public class ApplicationExample {
    @Bean
    public MyBean myBean() {
        return new MyBean();
    }

    public static void main(String[] args) {

        SpringApplication.run(ApplicationExample.class, args)
                         .getBean(MyBean.class)
                         .doSomething();
    }

    private static class MyBean {
        public void doSomething() {

In this example we are importing spring-boot-dependencies rather than inheriting spring-boot-starter-parent pom. 

package com.logicbig.example;

import org.apache.commons.codec.binary.Hex;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import java.nio.charset.StandardCharsets;

@SpringBootApplication
public class ApplicationExample {
    @Bean
    public MyBean myBean() {
        return new MyBean();
    }

    public static void main(String[] args) {
        ApplicationContext ctx =
                SpringApplication.run(ApplicationExample.class, args);
        MyBean bean = ctx.getBean(MyBean.class);
        bean.doSomething();
    }

    private static class MyBean {

        public void doSomething() {
            System.out.println("Doing something in MyBean");
            System.out.println(Hex.encodeHexString(
                    "ONE".getBytes(StandardCharsets.UTF_8)));
            System.out.println(Hex.class.getProtectionDomain()
                                        .getCodeSource()
                                        .getLocation());
        }
    }
}

In this example we are using spring-boot-starter and commons-codec dependencies. We are also changing versions in pom properties. 

package com.logicbig.example;

import org.apache.commons.codec.binary.Hex;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import java.nio.charset.StandardCharsets;

@SpringBootApplication
public class ApplicationExample {
    @Bean
    public MyBean myBean() {
        return new MyBean();
    }

    public static void main(String[] args) {
        ApplicationContext ctx =
                SpringApplication.run(ApplicationExample.class, args);
        MyBean bean = ctx.getBean(MyBean.class);
        bean.doSomething();
    }

    private static class MyBean {

        public void doSomething() {
            System.out.println("Doing something in MyBean");
            System.out.println(Hex.encodeHexString(
                    "ONE".getBytes(StandardCharsets.UTF_8)));
            System.out.println(Hex.class.getProtectionDomain()
                                        .getCodeSource()
                                        .getLocation());
        }
    }
}

Output
