我正在尝试将Spring Dependency Injection与我的Vaadin application/servlet集成。但是依赖注入不起作用。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
因为我可以看到我所需的对象，例如UserManager，mainWindow ...
然而，当涉及实际注射时，它似乎不起作用。我得到了nullpointerexceptions。
现在我正试图用MainWindow来测试它，这里应该注入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;
}
是的我知道我把@Autowired放在了两者上：setter和变量本身，但它无论如何都不起作用。
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，因为我可能达到了字符限制，但依赖项似乎并不缺乏imho。在pom.xml中我收到此错误：
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)
但是从命令行看，一切似乎都在编译好：

正如我所说，一切都达到了实际需要注入的地步，nullpointerexception之前没有错误消息。
任何人都知道什么是错的？
感谢。
