java - 自定义注释方面不起作用

Question

我正在尝试使用 @Around 建议为自定义注释编写方面，但有些原因它不调用。 这是我的代码:

@Aspect
@Component
public class AspectMeasureTime {
    @Around(value = "execution(* com.beh.businesslayer..*(..)) && @annotation(measureTime)")
    public void measureTime(ProceedingJoinPoint pjp, MeasureTime measureTime) throws Throwable {
    /*some code*/
    }
}

---

@Configuration
@ComponentScan(basePackages = {"com.beh"})
@EnableAspectJAutoProxy(proxyTargetClass = false)
public class WebConfig {
}

---

package com.beh.businesslayer.businessworkflows.pagefetcher;
public class PageFetcherWriter implements ItemWriter, StepExecutionListener {
    @MeasureTime("timee")
    private void printString(Object s) {
        logger.info("entry = " + s);
    }
}

---

package com.beh.businesslayer.businessworkflows.pagefetcher;
@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface MeasureTime {
    String value();
}

我尝试在没有此注释的情况下创建连接点，它工作正常。尝试使用@annotation(com.beh.businesslayer.businessworkflows.pagefetcher.MeasureTime)，它也不起作用。您知道为什么以及它应该是什么样子吗？

如果你要传递一个参数，那么你需要明确地告诉 AspectJ 它正在被传递

@Around(value = "execution(* com.beh.businesslayer..*(..)) && @annotation(measureTime) && args(measureTime)")
public void measureTime(ProceedingJoinPoint pjp, MeasureTime measureTime) throws Throwable {
