aopA.java

      package com.learningspring.aop;
public class aopA {
    public void m() {
        System.out.println("Actual business logic");
    }
}

BeforeAdvisor.java

      package com.learningspring.aop;

import java.lang.reflect.Method;
import org.springframework.aop.MethodBeforeAdvice;

public class BeforeAdvisor implements MethodBeforeAdvice {
    @Override
    public void before(Method method, Object[] args, Object target) throws Throwable {
             System.out.println("Additional concern before actual logic ");
    }
}

TestAOP.java

      package com.learningspring.aop;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;  

public class TestAOP {
    public static void main(String[] args) {
        Resource r = new ClassPathResource("applicationContext.xml");
        BeanFactory bf = new XmlBeanFactory(r);
        aopA a = (aopA) bf.getBean("proxy");
        a.m();
    }
}

Я запустил указанную выше программу, но получаю следующую ошибку:
