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="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

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

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