Prefil h2-console login data by request parameter

[Fachher]

Hi,

I have written a Spring ApplicationListener which logs the application URL after the application has been started. So that I can click on it and my browser opens the URL. Now I want to enhance this listener. It should also print the URL to the h2-console where the user enters a username, password, and jdbc url. Then I thought about a more convenient way. Providing this information via request parameter should be possible so that the input fields are prefilled. The user only needs to hit the connect button.

What do you think about this idea? I can create a pull request.

@Profile({ "default", "local" })
@AllArgsConstructor
@Slf4j
@Component
@ExcludeFromGeneratedCoverage // configuration
public class ApplicationInfoProvider implements ApplicationListener<ApplicationStartedEvent> {

    @Override
    public void onApplicationEvent(final ApplicationStartedEvent event) {
        final ConfigurableEnvironment environment = event.getApplicationContext().getEnvironment();
        final String contextPath = environment.getProperty("server.servlet.context-path", "").replace("/", "");
        final String serverPort = environment.getProperty("server.port", "8080");
        final String h2consolePath = environment.getProperty("spring.h2.console.path", "h2-console").replace("/", "");
        final String jdbcUrl = environment.getProperty("spring.datasource.url");
        final String dataSourceUsername = environment.getProperty("spring.datasource.username");
        final String dataSourcePassword = environment.getProperty("spring.datasource.password");

        final UriComponentsBuilder serverUri = UriComponentsBuilder.fromUriString("http://127.0.0.1").port(serverPort).pathSegment(contextPath);
        final UriComponentsBuilder h2Uri = serverUri.cloneBuilder().pathSegment(h2consolePath).queryParam("user_name", dataSourceUsername).queryParam("password", dataSourcePassword).queryParam("jdbc_url", jdbcUrl);
        log.info("Server url: {}", serverUri.toUriString());
        log.info("H2 url: {}", h2Uri.toUriString());
    }

}
