Interface used to indicate that a bean should run when it is contained within
\n a SpringApplication. Multiple CommandLineRunner beans can be defined
\n within the same application context and can be ordered using the Ordered
\n interface or @Order annotation.
\n If you need access to ApplicationArguments instead of the raw String array consider using ApplicationRunner.<\/p>\n","protected":false},"excerpt":{"rendered":"
