Spring Catalog File Overview:

List of jar packages required:

After the jar is imported, you will need to build path, select the jar right key build path-"Add Build Path"

First create Persion.java

Package Com.hpe.po;

public class Person {
	//requirement, the
	Print method ends public

	void Eat ()

		after the Print method starts//prints eating only after the eating is hit System.out.println ("Eat ...");
	}

	public void Drunk () {

		System.out.println ("Drunk ...");
	}
	
	public void Drunkbear () {

		System.out.println ("Drunkbear ...");
	}

	public void Play () {

		System.out.println ("Play ...");
	}

Then create the enhanced class: Myadvice.java

Package Com.hpe.po;

Import Org.aspectj.lang.ProceedingJoinPoint;

public class Myadvice {public

	void before () {
		System.out.println ("method Start");
	}

	public void End () {
		System.out.println ("method ended");
	}

	public void Final1 () {
		System.out.println ("Method End");
	}

	public void Around (Proceedingjoinpoint joinpoint) throws Throwable {
		System.out.println ("Method Bigin");
		Joinpoint.proceed ();
		System.out.println ("Method End");
	}

Configure Log4j.xml

# Global Logging Configuration
log4j.rootlogger=debug, stdout
# Console output ...
Log4j.appender.stdout=org.apache.log4j.consoleappender
log4j.appender.stdout.layout= Org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.conversionpattern=%5p [%t]-%m%n

Last configuration file:

Write Test class:

Package com.hpe.test;

Import Org.junit.Test;
Import Org.springframework.context.ApplicationContext;
Import Org.springframework.context.support.ClassPathXmlApplicationContext;


Import Com.hpe.po.Person;


public class Aoptest {
	@Test public
	void Test1 () {
		
		ApplicationContext context=new Classpathxmlapplicationcontext ("Applicationcontext.xml");
		Persion p= (persion) Context.getbean ("Persion1");
		Person person = Context.getbean ("person", person.class);
		Person.eat ();
		Person.drunk ();
	}
