Question

我在application-context.xml中定义了一个Aspect及其配置，如下所示：

<aop:aspectj-autoproxy proxy-target-class="true"/>
<bean id="myAspect" class="myAspectClass"/>
<aop:config>
    <aop:aspect ref="myAspect">
      <aop:pointcut id="myPointCut" expression="(@within(MyPointCutAnnotation) or @annotation(MyPointCutAnnotation)) and execution(* *(..))"/>
      <aop:before pointcut-ref="myPointCut" method="beforeMethod" />   
    </aop:aspect>
</aop:config>

我的servlet-context.xml看起来像这样：

<context:annotation-config />
    <context:component-scan base-package="mypackage" />

我的Spring Controller类：

@Controller
@RequestMapping( value="/xxx", method=RequestMethod.POST, consumes=MediaType.APPLICATION_JSON_VALUE )
public class MyController {  
    @MyPointCutAnnotation    
    @ResponseBody
    @RequestMapping( value="/signOn" )
    public void myMethod() {
        ...do something
    }  
}

web.xml如下：

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:application-context.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener> 
    <servlet>
        <servlet-name>appServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:servlet-context.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

但myPointCut不会被myMethod触发，除非我在servlet-context.xml中添加以下内容（导入根上下文），如下所示：

<import resource="classpath:application-context.xml"/ >

有人能告诉我为什么会这样吗？是不是所有bean都包括Aspect，PointCut和Advice在Spring中通过上下文层次结构自动在Controller中可用？

PointCut未在Spring Controller中触发
