Spring AOP with AspectJ not intercepting

I am writing my first AOP. I have pasted the code below which isnt getting intercepted on the method call. I am not sure what could be the reason.

On the console it only prints:

addCustomerAround() is running, args : dummy

and none of the AOP advice code is printed.

Can somebody help?

Interface:

package com.test.model;

import org.springframework.beans.factory.annotation.Autowired;

public interface AopInterface {


    @Autowired
    void addCustomerAround(String name);
}

Class:

package com.test.model;

import com.test.model.AopInterface;
import org.springframework.stereotype.Component;
import org.springframework.beans.factory.annotation.Autowired;

@Component
public class AopClass implements AopInterface {

    public void addCustomerAround(String name){
        System.out.println("addCustomerAround() is running, args : " + name);
    }
}

AOP:

package com.test.model;

import java.util.Arrays;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;



@Aspect
public class TestAdvice{


     @Around("execution(* com.test.model.AopInterface.addCustomerAround(..))")
       public void testAdvice(ProceedingJoinPoint joinPoint) throws Throwable {

        System.out.println("testAdvice() is running!");
        System.out.println("hijacked method : " + joinPoint.getSignature().getName());
        System.out.println("hijacked arguments : " + Arrays.toString(joinPoint.getArgs()));

        System.out.println("Around before is running!");
        joinPoint.proceed(); 
        System.out.println("Around after is running!");

        System.out.println("******");

       }
}

appcontext.xml:

<!-- Aspect -->
    <aop:aspectj-autoproxy />
    <bean id="AopClass" class="com.test.model.AopClass" />
    <bean id="TestAdvice" class="com.test.model.TestAdvice" />

POM:

<!-- AOP -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aop</artifactId>
            <version>${spring.version}</version>
        </dependency>

        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjrt</artifactId>
            <version>1.6.11</version>
        </dependency>

        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjweaver</artifactId>
            <version>1.6.11</version>
        </dependency>

Method call:

aoptest.addCustomerAround("dummy");

According to Aspect Oriented Programming with Spring, when a class implements interface(s), a JDK dynamic proxy will be used and if no interface is implemented then a CGLIB proxy will be created. To force CGLIB proxy you have to set proxy-target-class="true".

appcontext.xml:

<!-- Aspect -->
<aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy>
<bean id="AopClass" class="com.test.model.AopClass" />
<bean id="TestAdvice" class="com.test.model.TestAdvice" />

Output : 

testAdvice() is running!
hijacked method : addCustomerAround
hijacked arguments : [dummy]
Around before is running!
addCustomerAround() is running, args : dummy
Around after is running!

I don't see any error here. I've just tried your code and it works well. My test class:

public class App {
    public static void main(String[] args) throws Exception {

        ApplicationContext appContext = new ClassPathXmlApplicationContext("appcontext.xml");

        //-------------------------
        AopClass aopClass = (AopClass) appContext.getBean("AopClass");
        aopClass.addCustomerAround("dummy");
    }
}

enter image description here Result

Can you retry to build your maven project?! And try again?!
