What's the best way to Invoke a service on spring-boot start up?

I have a spring boot application and i need to invoke a service(a rest end point)on start up.

Solution

  • CommandLineRunner

    @Component
public class MyBean implements CommandLineRunner {

    public void run(String... args) {
        // Do something...
    }

}

    You can perform any task you'd like at Application startup with this handy interface.

    To call a REST endpoint you can use RestTemplate

    RestTemplate restTemplate = new RestTemplate();
String result = restTemplate.getForObject("http://www.example.com/api/resource", String.class);

    If you build a POJO with fields that match the JSON response, the RestTemplate will automatically map them with the help of Jackson. See the docs for more detail.
