Spring Boot CommandLineRunner Example

Date: 2024-04-08

Spring Boot's CommandLineRunner interface lets developers execute code after application startup. It's implemented by creating a class that implements the interface, containing a run method. This method is automatically invoked by Spring Boot once the application context is ready. CommandLineRunner can be used for tasks like database initialization or cache warming. It can be implemented directly or declared as a bean using the @Bean annotation. This provides a reliable and efficient way to perform startup tasks in Spring Boot applications.
