Here is the Test class App.java

package clientpack;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.mahesh.training.aop.Instrumentlist;

public class App {
   
    public static void main(String[] args) throws Exception {
        ApplicationContext ctx = new ClassPathXmlApplicationContext("/applicationContext.xml");
        Instrumentlist inst = (Instrumentlist)ctx.getBean("instrumentlist");
        inst.play();
    }

}

Output
