Spring Dependency Injection を Vaadin に統合しようとしていますapplication/servlet。ただし、依存性注入は機能しません。Spring はコンポーネントをうまく読み取ると思います。

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

のような必要なオブジェクトが表示されるのでUserManager、mainWindow...

しかし、実際に注入してみると、うまくいかないようです。私はそれでnullpointerexceptionsを取得します。

今、私はそれをテストしようとしています。注入MainWindowする必要があるアプリケーションは次のとおりです。MainWindow

    @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;
    }

はい@Autowired、セッターと変数自体の両方を配置していることはわかっていますが、どちらの方法でも機能しません。

メインウィンドウ:

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

私のweb.xml：

おそらく文字数制限に達する可能性があるため、依存関係を提供しませんでしたが、依存関係には私見が欠けているようには見えません。pom.xml で、次のエラーが発生します。

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)

しかし、コマンドラインからは、すべてがうまくコンパイルされているようです:

私が言ったように、実際に注入する必要があるポイントまですべてが機能し、前にエラーメッセージは表示されませんnullpointerexception。

誰が何が悪いのか知っていますか？

ありがとう。

VaadinリンクでSpringを使用するには、おそらくアドオンを使用する必要があります
