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.
