切入點到Spring @RequestMapping

我只是試圖在我的Spring項目上啓用AOP。我想在@RequestMapping完成後執行代碼（會話清理）。這是我的applicationContext.xml （只需加載引用的資源切入點到Spring @RequestMapping

這是方面類

package appname; 
import it.pstmarche.model.HibernateSessionFactory; 
import org.aspectj.lang.ProceedingJoinPoint; 
import org.aspectj.lang.annotation.AfterReturning; 
import org.aspectj.lang.annotation.Aspect; 
import org.aspectj.lang.annotation.Before; 
import org.aspectj.lang.annotation.Pointcut; 
import org.springframework.stereotype.Component; 
@Component 
@Aspect 
public interface SessionInterceptor { 

@Pointcut("execution(public * appname.ImplantManager+.*(..))") 
public void pc() ; 

@Before("pc()") 
public void print(); 
}

的接口的實現很簡單 @Before（「PC（）」）公衆void print（）{ System.out.println（「關於打電話打印Hello World」 }

我也嘗試了一些其他表達式，如：

@Pointcut（「執行（@ org.springframework.web.bind.annotation.RequestMapping公共*應用程序的名字*（..））」）
和許多其他

沒有運氣。我開始認爲問題不是表達式（我已經嘗試了大約10-15個類型......），但是這個類沒有在上下文中考慮。

作爲回答，請考慮：

名稱APPNAME旨在例如，obviusly
插入AOP：配置和AOP：AspectJ的自動代理只是一個嘗試，因爲我也在其他readed線程必須在由applicationContext加載的每個文件中啓用配置。我也試過只插入一個，但沒有結果
控制器具有註釋的接口+註釋的實現。我也嘗試沒有註釋界面或完全沒有結果

任何幫助嗎？ :)

編輯：響應axtavt ..對不起，我忘了加我的web.xml，這裏是一塊吧

<servlet> 
<description>context-servlet</description> 
    <servlet-name>appname Servlet</servlet-name> 
    <servlet-class> 
     org.springframework.web.servlet.DispatcherServlet 
    </servlet-class> 
    <init-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value> 
      classpath:appname-web-context.xml 
     </param-value> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
</servlet>

我正確加載通過Web-context.xml文件contextConfigLocation的。對不起，我忘了:-(

編輯2：我得到了答案我的錯誤由axtavt的建議！謝謝！

AOP在每個上下文的基礎上配置。

您有兩個上下文 - 根Web應用程序上下文（applicationContext.xml，其中包括導入其中的配置文件）和DispatcherServlet的應用程序上下文，其中聲明瞭控制器bean。

因此，爲了將方面應用到控制器，您需要將<aop:aspectj-autoproxy>添加到servlet特定的上下文中。

另請注意，不應在相同的基本包中使用<context:component-scan>，請參閱@Service are constructed twice。

已更新的問題。所以我很好地定義了調度程序上下文，但問題與多個上下文有關：組件掃描也許？ – Gtazok 2012-04-20 12:57:12

更新：感謝。我想清楚我錯過了什麼：在DispatcherServlet環境下掃描正確的軟件包！我在應用程序上下文的所有其他文件中正確掃描，但不是在這（這只是請求...，我錯過了！）再次感謝您！ – Gtazok 2012-04-20 13:28:19
