java.lang.IllegalArgumentException: warning no match for this type name: ru.sbt.filial.cards.aspect.SomeBean [Xlint:invalidAbsoluteTypeName]

Question

I never used Spring AOP and trying to configure my first bean. It seems that I configured it properly, but I get an exception that the bean is not found.

My aspect is –

@Aspect
@Component
public class IdentificationAspect {

    @Before("execution(* ru.sbt.filial.cards.aspect.SomeBean.*(..))")
    public void logBefore(JoinPoint joinPoint) throws Throwable {

        System.out.println("logBefore() is running!");
        System.out.println("hijacked : " + joinPoint.getSignature().getName());
        System.out.println("******");
    }
}

And my bean that AOP doesn't find is -

package ru.sbt.filial.cards.aspect;

import org.springframework.stereotype.Component;

@Component
public class SomeBean {

    public void printSmth() {
       System.out.println("!!!!!!!!!!!");
    }

}

I've got the following exception -

I have following maven dependencies -

              <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-aop</artifactId>
                <version>3.2.0.RELEASE</version>

              </dependency>

And my spring applicationContext.xml configuration is -

<mvc:annotation-driven/>
<aop:aspectj-autoproxy/>

<bean id="someBean" class="ru.sbt.filial.cards.aspect.SomeBean">
</bean>

UPDATE I added to my Spring configuration line

<context:component-scan base-package="ru.sbt.filial.cards.aspect"/>

but still same message. I also tried to annotate different ways - if I don't specify the bean i.e. write -

@Before("execution(* ru.sbt.filial.cards.aspect.*.*(..))")

instead

@Before("execution(* ru.sbt.filial.cards.aspect.SomeBean.*(..))")

I have no error on loading, but aop method is not invoked.

I also tried to annotate like this

@Before("this(ru.sbt.filial.cards.aspect.SomeBean) and execution(* printSmth(..))") 

but with same result - no match for this type name. Any more ideas??

Answer 1

I have the same problem as you and I've solved mine. I give you two suggestions, you can try it out. Please modify the @Before annotation in the aspect class as one of the following:

@Before("execution(* ru.sbt.filial.cards.aspect.SomeBean.logBefore(..))")

or

@Before("execution(* ru.sbt.filial.cards.aspect.SomeBean..*(..))")

Hope it helps.
