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 read

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();
        }
    }
}
