我有以下视图类：

@Route(value = NewsAdminView.ROUTE)
@RequiredArgsConstructor
public class NewsAdminView extends VerticalLayout {
    public static final String ROUTE = "";
    private final NewsService service;
    final Grid<News> grid = new Grid<>(News.class);

    @Override
    protected void onAttach(AttachEvent attachEvent) {
        addComponents();

        service.getNews().subscribe(items -> updateItems(attachEvent.getUI(), items));
    }

    private void updateItems(final UI ui, final List<News> news) {
        ui.access(() -> {
            grid.setItems(news);
            grid.setEnabled(true);
        });
    }

    // Some details are omitted, like setting up the components and handling security, locale & URL parameters
}

该服务执行 GraphQL 查询，该查询返回 Mono<List>，完成后将新闻条目添加到页面。AppShellConfigurator 具有必要的 @Push …
