Spring是否用java配置中的现有bean替换方法调用?

我的方法对吗 loadView 将仅调用一次(创建时 mainView 豆)?

@Configuration
public class Config {

    @Bean(name = "mainView")
    public View getMainView() throws IOException {
        return loadView("fxml/main.fxml");
    }

    @Bean
    public MainController getMainController() throws IOException {
        return (MainController) getMainView().getController();
    }

    @Bean
    public Step1Controller getStep1Controller() throws IOException {
        return getMainController().getStep1Controller();
    }

   ...
}
