Spring : Xml style configuration for pointcuts (Before advice)

The Aspect Class:

import org.aspectj.lang.JoinPoint;

//This is an Aspect class
public class LoggingAspect {

//This is an advice.
//Pointcut means where will this advice be applied.
public void log(JoinPoint joinPoint) {
System.out.println("common logging code executed for : "+joinPoint);


The configuration file:

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

<!-- Tells the container we will be using AspectJ.
Also tells the container to use the proxy approach for executing aspects -->
<aop:aspectj-autoproxy />

<bean id="customerService" class="service.CustomerServiceImpl" />

<bean id="loggingAspect" class="com.xxxx.LoggingAspect" />

<!-- Aop config start -->

<aop:pointcut expression="execution(public * apply*(..))" id="pointcut1" />
<aop:aspect ref="loggingAspect">
<aop:before method="log" pointcut-ref="pointcut1" />


Note that we are using "aop" namespace in the xml to configure it to aspect class.
