Pointcut NameMethodMatch using BeanFactory

A pointcut is a bunch of codes that picks out join points and exposes data from the execution context of those join points.Following is an example of NameMethodMatch using springConfig.xml.

SimpleBean.java

package roseindia.net.bean;

public class SimpleBean {
	String name;

	public String getName() {
		return name;
	}

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

	public void displayName() {
		System.out.println("Hello " + this.name);
	}
}

MainClaz.java

package roseindia.net.main;

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

import roseindia.net.bean.SimpleBean;

public class MainClaz {
	public static void main(String[] args) throws Exception {
		BeanFactory beanFactory = new XmlBeanFactory(new ClassPathResource(
				"springconfig/config.xml"));
		SimpleBean simpleBean = (SimpleBean) beanFactory.getBean("testBean");
		simpleBean.displayName();
	}
}

config.xml


<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"

    "http://www.springframework.org/dtd/spring-beans.dtd">
