Spring “瓦丁误差”；范围'；瓦丁视图'；对于当前线程不处于活动状态"；

我正在尝试使用附加组件com.Vaadin.Vaadin-spring.1.0.0创建Vaadin 7.5.5应用程序。这不是Spring Boot应用程序，而是可以使用Spring上下文部署的war，它应该引导Vaadin

错误是：

当前线程的作用域“vaadin view”未处于活动状态

嵌套异常为java.lang.IllegalStateException:无活动视图

以下是完整的错误跟踪：

以下是应用程序主类：

@Theme("valo")
@SpringUI
public class VaadinSpringApplication extends UI {

    @Configuration
    @EnableVaadin
    public static class VaadinSpringApplicationConfiguration {}
    
    @Autowired
    SpringViewProvider viewProvider;

    @Override
    protected void init(VaadinRequest request) {
        Navigator navigator = new Navigator(this, this);
        navigator.addProvider(viewProvider);
        navigator.navigateTo(DefaultView.NAME);
    }
}

DefaultView.java

@SpringComponent
@SpringView(name = DefaultView.NAME)
public class DefaultView extends CustomComponent implements View {

    public static final String NAME = "defaultView";

    @Override
    public void enter(ViewChangeListener.ViewChangeEvent event) {
        VerticalLayout layout = new VerticalLayout();
        layout.setMargin(true);
        Button button = new Button("Click Me");
        setCompositionRoot(layout);
    }
}

从日志中可以看到，SpringBean（viewCache、defaultView、springLoginView、springMainView）已经创建。但是，一旦我尝试将其注入到主类中，就会出现错误“作用域'vaadin view'对于当前线程不处于活动状态”

请给我一些建议。谢谢。

您也可以分享您的DefaultView实现吗？@mstahv请查看uptadesI无法重现您的问题。您的Spring上下文设置可能有问题？我举了个例子：Mstahv，谢谢！一旦我修改了DefaultView如下：@SpringView（name=DefaultView.name）公共类DefaultView扩展了VerticalLayout实现视图{…}您是否也可以共享您的DefaultView实现？@mstahv请查看uptadesI无法重现您的问题。您的Spring上下文设置可能有问题？我举了个例子：Mstahv，谢谢！一旦我修改了DefaultView如下：@SpringView（name=DefaultView.name）公共类DefaultView扩展了VerticalLayout实现了视图{…}
