[FIXED] Can i configure the Spring MVC application so that when ever i run the application, the controller or any method should be called automatically

Issue

I have developed a spring application with rest controller which will have only one GET method. Can i configure the Spring MVC application so that when ever i run the application, the controller or any method should be called automatically with out hitting the api from browser(Just like stand alone application)

Solution

You can create a bean that implements org.springframework.boot.CommandLineRunner interface.

E.g.

@Component
public class MyRunner implements CommandLineRunner {
@Override
    public void run(String... args) throws Exception {
        // Do stuff here at startup
    }
}

As this is a regular Spring component, you can use field or constructor injection to inject other Spring components.
