Can't find referenced pointcut

问题

I'm developing my first aspect and I'm encountering the following trouble.

MyAspect class:

@Component
@Aspect
public class MyAspect{


@Pointcut("execution(* com.mypackage.MyClass.method(..))")
public void sendComunication(){}

@AfterReturning("sendComunication()")
public void sendComunicationMail() {

    //TODO somethings
}

}

Then i added "aop:aspectj-autoproxy" and aop namespace in the applicationContext. Now when i try to build my application, i get this error:

    Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.transaction.annotation.AnnotationTransactionAttributeSource#0': Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: error at ::0 can't find referenced pointcut sendComunication

Where am I doing wrong?

回答1:

This post hints that you need to upgrade to a newer version of aspectj. Get it here.

回答2:

It is unable to find the aspect whatever you have mentioned ( i. e "execution(* com.mypackage.MyClass.method(..))" ). method signature might be wrong.

回答3:

I've met the same problem recently. The answer is change our version of aspectj to a new version. Just like Sotirios Delimanolis says.

回答4:

The problem was that

com.mypackage.MyClass

wasn't a bean managed to Spring, but instead it was a method in vaadin panel
