In this example you will learn how to match the method name using BeanFactory.

In this example you will learn how to match the method name using BeanFactory.

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
