where is the pointcut in this example?

[Samanthi perera]

this is my impl class

package com.spring.aop;

public class AdderImpl implements Adder {

	public int add(int a, int b){
        return a+b;
    }

}

this is my advice

package com.spring.aop;

import java.lang.reflect.Method;
import org.springframework.aop.MethodBeforeAdvice;

public class LogBeforeCallAdvice implements MethodBeforeAdvice{

    public void before(Method method, Object[] args, Object target) {
        System.out.println("Before Calling the Method");
    }

}

this is my test class

package com.spring.aop;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.core.io.*;

public class AdderTest {

    public static void main(String args[]){

    	ApplicationContext factory =new ClassPathXmlApplicationContext("hello.xml");   
        Adder adder = (Adder)factory.getBean("adder");
        int result = adder.add(10,10);
        System.out.println("Result = " + result);

       // result = adder.add(0,0);
        System.out.println("Result = " + result);        
    }
}

this is my xml file

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

	<bean id="beforeCall" class="com.spring.aop.LogBeforeCallAdvice" />

	<!-- Implementation Class -->
	<bean id="adderImpl" class="com.spring.aop.AdderImpl" />

	<!-- Proxy Implementation Class -->
	<bean id="adder" class="org.springframework.aop.framework.ProxyFactoryBean">

		<property name="proxyInterfaces">
			<value>com.spring.aop.Adder</value>
		</property>

		<property name="interceptorNames">
			<list>
				<value>beforeCall</value>
			</list>
		</property>

		<property name="target">
			<ref bean="adderImpl" />
		</property>
	</bean>

</beans>

this examle working fine.
but my problem is where is the pointcut in this example?

I'd recommend spending some time with the Spring AOP API reference docs; there does not need to be an explicit pointcut when you're advising an interface. Everything in the interface is included (at least that's my understanding).
