Spring DI NullPointerException @Autowired fail

Мое имя Daniel и я новичок Java и WebApplications. У меня вопрос, потому что у меня проблема с NullPointerException.Spring DI NullPointerException @Autowired fail

Я изучаю инъекцию зависимой от весны. Я сделал ошибку, но не могу ее найти. Благодарим вас за помощь.

public class EmailServiceImpl implements MessageService { 
    @Override 
    public String getMessage(String messageName) { 
     return "EMAIL_SERVICE"; 
    } 
} 

public class NotifyServiceImpl implements MessageService { 
    @Override 
    public String getMessage(String messageName) { 
     return "NOTIFY_SERVICE"; 
    } 
} 

@Component 
public interface MessageService { 
    public String getMessage(String messageName); 
} 

@Configuration 
public class DIConfiguration { 

    @Bean 
    public MessageService getMessageService(){ 
     return new NotifyServiceImpl(); 
    } 
} 


//vaadin init first class  
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(); 
     context.register(DIConfiguration.class); 
     context.refresh(); 
     MessageService message = context.getBean(MessageService.class); 

     Notification.show(message.getMessage("dfsa")); 
//it works 



     //context.close(); 
//different class 
//it doesn't work 
@Autowired 
    private MessageService messages; 

Notification.show(messages.getMessage("first"));

// трассировки стека //

пожалуйста post полный стек следы. Это поможет с точным указанием выводов. Также аннотацию '@ Component' следует применять к классу, а не по интерфейсу –

Любой может помочь? – danieloo

Очевидно, что в вашем классе 'HelpView' (первый внутренний класс) произошла ошибка из-за этой строки стека ошибок:' pl.infotower.views.HelpView $ 1.buttonClick (HelpView.java:52) '. Не могли бы вы показать нам код этого класса, особенно все, что касается линии 52? –

Теперь я ошибаюсь в HelpView, но теперь я не знаю, в чем причина.

package pl.xxx.views; 


import com.vaadin.navigator.View; 
import com.vaadin.navigator.ViewChangeListener.ViewChangeEvent; 
import com.vaadin.shared.ui.label.ContentMode; 
import com.vaadin.ui.Button; 
import com.vaadin.ui.Label; 
import com.vaadin.ui.Notification; 
import com.vaadin.ui.VerticalLayout; 
import org.springframework.beans.factory.annotation.Autowired; 
import pl.xxx.data.ExampleUtil; 
import pl.xxx.spring.di.MessageService; 
import pl.xxx.models.CalculatorModel; 
import pl.xxx.ui.MainMenuComponent; 
import pl.xxx.presenters.CalculatorPresenter; 


public class HelpView extends VerticalLayout implements View { 

    @Autowired 
    private MessageService messages; 

    public HelpView() { 
     setSizeFull(); 
     setSpacing(true); 
     addComponent(new MainMenuComponent()); 
     addComponent(headingLabel()); 
     addComponent(someText()); 
     addComponent(redirectButton()); 
     addComponent(calculator()); 
    } 

    @Override 
    public void enter(ViewChangeEvent event) { 
     Notification.show("Showing view: Help!"); 
    } 

    private Label headingLabel() { 
     return new Label("Help"); 
    } 

    private Label someText() { 
     Label label = new Label(ExampleUtil.lorem); 
     label.setContentMode(ContentMode.HTML); 
     return label; 
    } 

    private Button redirectButton(){ 
     Button button = new Button("Calculator", new Button.ClickListener(){ 
      public void buttonClick(Button.ClickEvent event){ 
      Notification.show(messages.getMessage("first")); 
      } 
     }); 
     return button; 
    } 

    private CalculatorViewImpl calculator() { 
     CalculatorModel model = new CalculatorModel(); 
     CalculatorViewImpl view = new CalculatorViewImpl(); 
     new CalculatorPresenter(model, view); 
     return view; 
    } 

}

Vaadin объекты изначально не управляется Spring контейнером. Поэтому аннотация @Autowired, используемая в классе HelpView, не выполняется. Чтобы привести пример в работу, вам нужно сделать некоторые интеграционные усилия. Есть несколько различных подходов, которые можно найти в блогах и учебниках в Интернете.

Один из подходов, работающих, не меняя ваш пример кода на много, использует @AspectJ. Я объясню это с помощью Maven как инструмента управления. Пожалуйста, примите необходимые шаги, если вы управляете своим проектом по-другому.

Главная точка: аннотировать классы Vaadin (или любые другие не пружинные классы), а также нуждающихся в возможности автоматического связывания/впрыска с @Configurable. Не забудьте добавить запись <context:spring-configured /> в файл контекста приложения, показанный ниже. Таким образом AspectJ будет делать все волшебство необходимое:

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.beans.factory.annotation.Configurable; 

@Configured 
public class HelpView extends VerticalLayout implements View { 

    @Autowired 
    private MessageService messages; 

    ...

Получить AspectJ работать

сам AspectJ будет нуждаться в некоторой конфигурации. Прежде всего необходимо вызвать компилятор AspectJ. С помощью Maven вы достичь, используя следующий плагин (скопировать XML на ваш pom.xml, как ребенка <plugins />):

 <plugin> 
      <groupId>org.codehaus.mojo</groupId> 
      <artifactId>aspectj-maven-plugin</artifactId> 
      <version>1.4</version> 
      <configuration> 
       <source>1.6</source> 
       <target>1.6</target> 
       <aspectLibraries> 
        <aspectLibrary> 
         <groupId>org.springframework</groupId> 
         <artifactId>spring-aspects</artifactId> 
        </aspectLibrary> 
       </aspectLibraries> 
      </configuration> 
      <executions> 
       <execution> 
        <goals> 
         <goal>compile</goal> 
         <goal>test-compile</goal> 
        </goals> 
       </execution> 
      </executions> 
     </plugin>

Во-вторых, AspectJ выполнения и в Spring AOP RESSOURCES необходимы. Скопируйте следующие строки в Maven <dependencies /> элемента (в pom.xml):

<dependency> 
     <groupId>org.aspectj</groupId> 
     <artifactId>aspectjrt</artifactId> 
     <version>1.6.11</version> 
    </dependency> 
    <dependency> 
     <groupId>org.springframework</groupId> 
     <artifactId>spring-aspects</artifactId> 
     <version>3.2.1.RELEASE</version> 
    </dependency>

Наконец вам нужна запись конфигурации в приложений контекст файла (Bean.xml, корневой context.xml, applicationContext.xml, или независимо от имени вашего XML-файла объявления с вашими бобами).

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:context="http://www.springframework.org/schema/context" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 

    <context:spring-configured />

Версия номер версий я выбрал работу в моей среде вместе хорошо.Возможно, нужно изменить их соответственно своей среде.
