Spring AOP不起作用

我使用Spring AOP作爲我的應用程序的日誌記錄系統。但我有一些麻煩。Spring AOP不起作用

我有簡單的類

@Component 
@Scope(BeanDefinition.SCOPE_PROTOTYPE) 
public class MessageReceiverImpl implements MessageReceiver { 
    final private BufferedReader reader; 

    public MessageReceiverImpl(BufferedReader reader) { 
     this.reader = reader; 
    } 
    public String receive(){ 
     String msg = null; 
     try { 
      msg = reader.readLine(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
     return msg; 
    } 
}

;記錄儀類piontcut爲MessageReceiverImpl

@Aspect 
public class LoggerMessage { 

    private static final Logger log = Logger.getLogger("listenerLogger"); 

    @Before("execution(* server.logic.listener.message.MessageReceiverImpl.receive(..))") 
    public void logMessageReceiver() { 
     log.info("INFO : LoggerMessage -> new Client"); 
    } 
}

而且我bean.xml

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns:aop="http://www.springframework.org/schema/aop" 
     xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
    http://www.springframework.org/schema/aop 
    http://www.springframework.org/schema/aop/spring-aop-3.0.xsd "> 

    <aop:aspectj-autoproxy> 
     <aop:include name="loggerMessage"/> 
    </aop:aspectj-autoproxy> 
    <aop:aspectj-autoproxy proxy-target-class="true"/> 

    <!-- Aspect --> 
    <bean id="loggerMessage" class="service.logger.listener.LoggerMessage" /> 

</beans>

但它不執行之前收到。（）方法。其他日誌類工作良好。我在哪裏遇到問題？

更多信息。創建instatnce

@Bean 
@Scope(BeanDefinition.SCOPE_PROTOTYPE) 
UploadSession getSession(Socket socket) { 
    UploadSessionImpl uploadSession = null; 
    try { 
     uploadSession = new UploadSessionImpl(socket); 

     BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream())); 
     MessageReceiver receiver = new MessageReceiverImpl(reader); 
     uploadSession.setReceiver(receiver); 

     PrintWriter out = new PrintWriter(socket.getOutputStream(), true); 
     MessageSender sender = new MessageSenderImpl(out); 
     uploadSession.setSender(sender); 

     uploadSession.setBaseDir(context.getEnvironment().getProperty("listener.test-runs-folder")); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
    return uploadSession; 
}

使用

public class UploadSessionImpl implements UploadSession,  ApplicationContextAware { 

private MessageReceiver receiver; 

public UploadSessionImpl(Socket socket) throws IOException { 
    this.socket = socket; 
} 

public void process() throws IOException { 
    String msg; 

    while (true) { 
     msg = receiver.receive(); 
     if (msg.equals("close")) break; 
     ... 
    } 
}

你有'aop：aspectj-autoproxy'應該被刪除的重複條目。還要保留'proxy-target-class =「true」' –

你如何創建'MessageRecieverImpl'類的實例？這個配置如何加載？這裏的信息太少了......請提供一個可以複製此信息的樣本，而不僅僅是片段。 –

@M。 Deinum我添加了一些更多的信息 –

到目前爲止，從你的代碼，看起來你與bean創建配置搞亂。試試這些：

@Bean 
    @Scope(BeanDefinition.SCOPE_PROTOTYPE) 
    public BufferedReader bufferedReader(Socket socket) throws Exception { 
     return new BufferedReader(new InputStreamReader(socket.getInputStream())); 
    } 

    @Bean 
    @Scope(BeanDefinition.SCOPE_PROTOTYPE) 
    public MessageReceiver receiver(BufferedReader bufferedReader) { 
     return new MessageReceiverImpl(bufferedReader); 
    } 

    @Bean 
    @Scope(BeanDefinition.SCOPE_PROTOTYPE) 
    UploadSession getSession(Socket socket, MessageReceiver receiver) { 
     UploadSessionImpl uploadSession = null; 
     try { 
      uploadSession = new UploadSessionImpl(socket); 

      BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream())); 
      uploadSession.setReceiver(receiver); 

      PrintWriter out = new PrintWriter(socket.getOutputStream(), true); 
      MessageSender sender = new MessageSenderImpl(out); 
      uploadSession.setSender(sender); 

      uploadSession.setBaseDir(context.getEnvironment().getProperty("listener.test-runs-folder")); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
     return uploadSession; 
    }
