Launch browser automatically after spring-boot webapp is ready

Question

How do I launch a browser automatically after starting the spring boot application.Is there any listener method callback to check if the webapp has been deployed and is ready to serve the requests,so that when the browser is loaded , the user sees the index page and can start interacting with the webapp?

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
    // launch browser on localhost 
}

Answer 1

Below code worked for me:

@EventListener({ApplicationReadyEvent.class})
void applicationReadyEvent() {
    System.out.println("Application started ... launching browser now");
    browse("www.google.com");
}

public static void browse(String url) {
    if(Desktop.isDesktopSupported()){
        Desktop desktop = Desktop.getDesktop();
        try {
            desktop.browse(new URI(url));
        } catch (IOException | URISyntaxException e) {
            e.printStackTrace();
        }
    }else{
        Runtime runtime = Runtime.getRuntime();
        try {
            runtime.exec("rundll32 url.dll,FileProtocolHandler " + url);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

@SpringBootApplication
@ComponentScan(basePackageClasses = com.io.controller.HelloController.class)
public class HectorApplication {

    public static void main(String[] args) throws IOException {
       SpringApplication.run(HectorApplication.class, args);
       openHomePage();
    }

    private static void openHomePage() throws IOException {
       Runtime rt = Runtime.getRuntime();
       rt.exec("rundll32 url.dll,FileProtocolHandler " + "http://localhost:8080");
    }
}
