CommandLineRunner (Spring Boot API)

Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface CommandLineRunner
```
Interface used to indicate that a bean should run when it is contained within a SpringApplication. Multiple CommandLineRunner beans can be defined within the same application context and can be ordered using the Ordered interface or @Order annotation.
If you need access to ApplicationArguments instead of the raw String array consider using ApplicationRunner.
