spring aop logging advice is not getting called - spring

Question

I am writing simple aspect with simple logging advice which will be called upon setter of class.
Below is code Snippet
AopMain.java
package com.example.test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.example.test.model.Triangle;
import com.example.test.service.ShapeService;
public class AopMain {
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
//ShapeService shapeService = context.getBean("shapeService", ShapeService.class);
//shapeService.getTriangle().setName("triangle");
Triangle triangle = new Triangle();
triangle.setName("triangle class");
System.out.println(triangle.getName());
}
}
Triangle.java
package com.example.test.model;
public class Triangle {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
System.out.println(name);
}
}
LoggingAspect.java
package com.example.test.aspect;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.springframework.stereotype.Component;
import com.example.test.model.Triangle;
#Component
#Aspect
public class LoggingAspect {
#Before("execution(public * *(..))")
public void LoggingAdvice(JoinPoint jPoint) {
System.out.println("Advice run. Get method is called " + jPoint.getTarget());
Triangle triangle = (Triangle) jPoint.getTarget();
}
#Before("args(name)")
public void test(String name) {
System.out.println("logging advice args " + name);
}
}
Output
triangle class
triangle class
spring.xml
<?xml version="1.0" encoding="UTF-8"?>

class="com.example.test.service.ShapeService" autowire="byType" />
<aop:aspectj-autoproxy />
<context:component-scan

</beans>
spring is working properly.
I do not understand why aspect is not gettting called.
please help me to understand this issue.
