我尝试使用附加组件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上下文部署的战争，它应该引导Vaadin。
错误是：
范围＆＃39; vaadin-view＆＃39;当前线程
无效嵌套异常是java.lang.IllegalStateException：没有活动视图
这是完整的错误跟踪：

这是应用程序主类：
@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);
}
}
正如您在日志中看到的那样，已经创建了spring bean（viewCache，defaultView，springLoginView，springMainView）。但是，一旦我试图将它注入主要课程 - 得到错误＆＃34; 范围＆＃39; vaadin-view＆＃39;当前线程无法激活＆＃34;。
请指教。谢谢。
