java - Vaadin - Spring Boot でカスタマイズされたサーブレットの productionMode

Question

プロジェクトを本番モードにしようとしていますが、うまくいきません:(

起動ログではすべて問題ないようです。

しかし、アプリケーションにアクセスすると:

vaadin 用のカスタム サーブレットを使用しています。コメントすると (vaadin spring boot auto config によって提供されるデフォルトを使用すると)、DEBUG 情報は表示されません...

@Bean(name = "springBootServletRegistrationBean")
    public ServletRegistrationBean servletRegistrationBean() {
        SpringVaadinServlet servlet = new SpringVaadinServlet() {

            @Override
            protected VaadinServletService createServletService(DeploymentConfiguration deploymentConfiguration) throws ServiceException {
                SpringVaadinServletService service = new SpringVaadinServletService(this, deploymentConfiguration, null) {
...

誰かが私が間違っていることを知っていますか?
