与Vaadin的Spring集成不起作用

Question

我正在尝试将Spring Dependency Injection与我的Vaadin application/servlet集成在一起。 但是，依赖项注入无效。 我认为Spring可以很好地读取组件：

2013-01-15 06:57:11,361 [localhost-startStop-1] INFO  org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Loading XML bean definitions from class path resource [com/nortal/pirs/spring/application-context.xml]
2013-01-15 06:57:12,012 [localhost-startStop-1] INFO  org.springframework.beans.factory.support.DefaultListableBeanFactory - Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@fa5214b: defining beans [org.springframework.context.annotation.internalConfigurationAnnotationProcessor,org.springframework.context.annotation.internalAutowiredAnnotationProcessor,org.springframework.context.annotation.internalRequiredAnnotationProcessor,org.springframework.context.annotation.internalCommonAnnotationProcessor,org.springframework.context.annotation.internalPersistenceAnnotationProcessor,org.springframework.context.config.internalBeanConfigurerAspect,mainController,UserManager,VisitManager,mainWindow,org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor#0,org.springframework.context.annotation.CommonAnnotationBeanPostProcessor#0,org.springframework.context.annotation.ConfigurationClassPostProcessor$ImportAwareBeanPostProcessor#0]; root of factory hierarchy

由于我可以看到所需的对象，例如UserManager ， mainWindow ...

但是，当涉及到实际注射时，它似乎不起作用。 我得到nullpointerexceptions。

现在，我正在尝试使用MainWindow进行测试，这是应该注入MainWindow的应用程序：

    @Configurable
public class PirsVaadinController extends Application implements
        NavigatorInterface {

    private String title = "WELCOME";
    private transient Logger log;
    private Map userData;
    private boolean useFakeData = false;

    @Autowired
    private MainWindow mainWindow;

public UserManagerInterface getUserManager() {
        return userManager;
    }

    @Autowired
    public void setUserManager(UserManagerInterface userManager) {
        this.userManager = userManager;
    }

是的，我知道我在设置器和变量本身上都使用了@Autowired ，但是这两种方法均无效。

主窗口：

 @org.springframework.stereotype.Component
@org.springframework.context.annotation.Scope("session")
public class MainWindow extends Window {

我没有提供依赖项，因为我可能已经达到字符数限制，但是依赖项似乎并没有缺少恕我直言。 在pom.xml中，我确实收到此错误：

Multiple annotations found at this line:
- Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:aspectj-maven-plugin:1.2:test-compile (execution: default, phase: 
 process-test-sources)
- Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:aspectj-maven-plugin:1.2:compile (execution: default, phase: process-
 sources)

但是从命令行来看，一切似乎都编译良好：

 mvn compile

就像我说的，一切正常，实际上需要注入，在nullpointerexception之前没有错误消息。

有人知道怎么了吗？

谢谢。

您可能应该使用插件在Vaadin中使用Spring 链接
