Unable to understand output

[raja singh kumar]

Hi,

I am just trying my hands on spring aop. I am confused with the output. In the MainApp class when I comment the setter then I get advice logs 2 times in the output. But when I use the setter in MainApp class I get advice log only once. I am not sure why it is coming only once whereas there are 2 getters which are called from MainApp?

Thanks for your help

Circle.java

package com.spring.model;

public class Circle {
	String name;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
	
	
}

LoggingAspect.java

package com.spring.model;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;

@Aspect
public class LoggingAspect {
	@Before("execution(* get*())")
	public void LoggingAdvice(){
		System.out.println("Logging advice run...get method called");
	}
	
}

ShapeService.java

package com.spring.model;

public class ShapeService {
	private Circle circle;
	private Triangle triangle;

	public Triangle getTriangle() {
		return triangle;
	}

	public void setTriangle(Triangle triangle) {
		this.triangle = triangle;
	}

	public Circle getCircle() {
		return circle;
	}

	public void setCircle(Circle circle) {
		this.circle = circle;
	}
	
	
}

Triangle.java

package com.spring.model;

public class Triangle {
	String name;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}
	
}

MainApp.java

package com.spring.main;

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

import com.spring.model.Circle;
import com.spring.model.ShapeService;

public class MainApp {
	public static void main(String[] args) {
		System.out.println(1);
		ApplicationContext context=new ClassPathXmlApplicationContext("Beans.xml");		
		ShapeService shapeService=(ShapeService)context.getBean("shapeService");
//		shapeService.setCircle(new Circle());
		shapeService.getCircle().getName();
	}
}

Output when setter is commented in MainApp:
Logging advice run...get method called
Logging advice run...get method called

Output when setter is used in MainApp:
Logging advice run...get method called
