Java Vaadin无弹簧靴问题

我目前正在做一个不使用Spring Boot的Vaadin Spring应用程序。我已按照说明加载带注释的Spring设置。已加载设置，但随后会弹出此异常：

严重：路径为[/dashboard]的上下文中Servlet[poc.spring.vaadin.dashboard.config.SpringVaadinServlet]的Servlet.service（）引发异常[com.vaadin.server.ServiceException:org.springframework.beans.factory.BeanCreationException:创建名为'poc.spring.vaadin.dashboard.DashboardUI'的bean时出错：自动关联依赖项的注入失败；嵌套异常为org.springframework.beans.factory.BeanCreationException:无法自动关联字段：private com.vaadin.spring.navigator.SpringViewProvider poc.spring.vaadin.dashboard.DashboardUI.viewProvider；嵌套异常为java.lang.IllegalArgumentException:未找到具有根本原因的有效com.vaadin.spring.internal.UIID实例！] java.lang.IllegalArgumentException:未找到有效的com.vaadin.spring.internal.UIID实例

这是我的主要UI代码：

 @SuppressWarnings("serial")
 @Theme("dashboardTheme")
 @SpringUI()
 public class DashboardUI extends UI {

@Autowired
private SpringViewProvider springViewProvider;

@Autowired
private PostValuesService postValuesService;

SampleSideBar sampleSideBar = new SampleSideBar();
LoginComponent loginComponent = new LoginComponent();

private TransMonitoring getTransGrid() throws ParseException {

    Collection<PostValue> transList = postValuesService.getAllPostValues(null, null, null, null, null, null, null,
            null, null, null, 100);
    System.out.println(transList.size());
    BeanItemContainer<PostValue> container = new BeanItemContainer<PostValue>(PostValue.class, transList);
    return new TransMonitoring(container);
}

@Override
protected void init(VaadinRequest request) {
    final VerticalLayout root = new VerticalLayout();
    // root.setSizeFull();
    root.setMargin(true);
    root.setSpacing(true);

    root.addComponent(loginComponent);
    root.setComponentAlignment(loginComponent, Alignment.MIDDLE_CENTER);
    setContent(root);

     Navigator navigator = new Navigator(this, root);
     navigator.addProvider(springViewProvider);
}

希望这里有人能帮助我

谢谢！

请不要添加代码的截图。只需将代码放入文本中（用四个字符缩进）即可显示为ok。然后，其他人可以编辑该代码，将其用于答案，并可以进行搜索。已将更改的截图更新为代码。
