AOP切入點匹配Spring Step.execute（...）方法

我正在嘗試使用AspectJ AOP攔截對Spring批處理步驟執行的調用，並建議要登錄的文件。AOP切入點匹配Spring Step.execute（...）方法

繼this example的配置，我的切入點是這樣的：

@Before("execution(* org.springframework.batch.core.Step.execute(..)) && " + "args(stepExecution)") 
public void setupLogging(Object stepExecution) {...} 

@After("execution(* org.springframework.batch.core.Step.execute(..))") 
public void tearDownLogging() {...}

使用下面的測試（和一個類似的，當我推倒我的記錄），切入點比賽，但不要似乎當我嘗試部署它們時工作。

@Test 
    public void testSetupLoggingMatcher() throws NoSuchMethodException, SecurityException { 
     java.lang.reflect.Method method = LoggingAspect.class.getMethod("setupLogging", Object.class); 
     Annotation[] annotations = method.getDeclaredAnnotations(); 

     boolean matched = false; 
     for (Annotation annotation: annotations) { 
      if (annotation.annotationType() == org.aspectj.lang.annotation.Before.class) { 
       org.aspectj.lang.annotation.Before beforeAnnotation = (org.aspectj.lang.annotation.Before) annotation; 
       String pointcutstring = beforeAnnotation.value(); 
       PointcutParser pointcutParser = 
         PointcutParser.getPointcutParserSupportingAllPrimitivesAndUsingContextClassloaderForResolution(); 
       Collection<PointcutParameter> parameters = new ArrayList<PointcutParameter>(); 
       parameters.add(new PointcutParameter() { 

        @Override 
        public Class getType() { 
         return StepExecution.class; 
        } 

        @Override 
        public String getName() { 
         return "stepExecution"; 
        } 

        @Override 
        public Object getBinding() { 
         return mockStepExecution; 
        } 
       }); 
       PointcutExpression pointcut = 
         pointcutParser.parsePointcutExpression(pointcutstring, LoggingAspect.class, 
           parameters.toArray(new PointcutParameter[0])); 
       ShadowMatch match = pointcut.matchesMethodExecution(Step.class.getMethod("execute", StepExecution.class)); 
       matched = matched || match.alwaysMatches(); 
      } 
     } 
     assertTrue("No pointcuts on setupLogging matched Step.execute(StepExecution.class)", matched); 
    }

我已驗證我的切入點匹配Step接口，並且我的Aspect正在ApplicationContext中初始化。但是，當我嘗試運行作業時，切入點不會被觸發。爲什麼會發生？有什麼方法可以解決它嗎？
