JavaFX : Integrating Spring framework with JavaFX app(Incorrect configuration)

Question

I am working on a JavaFX application and I would like to integrate Spring functionality with it. Currently the code compiles without any error, but when I request service la

You have created a SpringFxmlLoader but you are not using it. You want

SpringFxmlLoader loader = new SpringFxmlLoader();
Parent root = (Parent) loader.load(getClass().getResource("login.fxml").toExternalForm());

instead of using the FXMLLoader directly.

I would actually write the SpringFxmlLoader differently, so that it matched the standard FXMLLoader API a little more closely:

public class SpringFxmlLoader {

    private static final ApplicationContext applicationContext = new AnnotationConfigApplicationContext(ApplicationConfiguration.class);

    public <T> T load(URL url) {
        try  {
            FXMLLoader loader = new FXMLLoader(url);
            loader.setControllerFactory(applicationContext::getBean);
            return loader.load();
        } catch (IOException ioException) {
            throw new RuntimeException(ioException);
        }
    }
}

Then your start method looks like:

SpringFxmlLoader loader = new SpringFxmlLoader();
Parent root = loader.load(getClass().getResource("login.fxml"));

You might need to tinker with the exact path to get things right, depending on your setup.
