Static Pointcut

Static pointcuts are based on method and target class, they cannot take into account the methods arguments.

SimpleBean.java

package roseindia.net.pointcut;

public class SimpleBean {
	public void greetMethod() {
		System.out.println("Have a Peaceful Day");
	}
}

SimpleAdvice.java

package roseindia.net.pointcut;

import org.aopalliance.intercept.MethodInterceptor;
import org.aopalliance.intercept.MethodInvocation;

public class SimpleAdvice implements MethodInterceptor {

	@Override
	public Object invoke(MethodInvocation methodInvocation) throws Throwable {
		// TODO Auto-generated method stub
		System.out.println("Calling " + methodInvocation.getMethod().getName());
		Object obj = methodInvocation.proceed();
		System.out.println("proceed...........");
		return obj;
	}

}

SimplePointCut.java

package roseindia.net.pointcut;

import java.lang.reflect.*;

import org.springframework.aop.ClassFilter;
import org.springframework.aop.support.ClassFilters;
import org.springframework.aop.support.StaticMethodMatcherPointcut;

public class SimplePointCut extends StaticMethodMatcherPointcut {

	@Override
	public boolean matches(Method method, Class clazz) {
		// TODO Auto-generated method stub
		return ("greetMethod".equals(method.getName()));
	}

import org.springframework.aop.framework.ProxyFactory;
import org.springframework.aop.support.DefaultPointcutAdvisor;
import org.springframework.aop.support.Pointcuts;

	public static void main(String[] args) {
		SimpleBean simpleBean = new SimpleBean();
		SimpleBean beanProxy;
		Pointcut pointcut = new SimplePointCut();
		Advice advice = new SimpleAdvice();
		Advisor advisor = new DefaultPointcutAdvisor(pointcut, advice);

		ProxyFactory proxyFactory = new ProxyFactory();
		proxyFactory.addAdvisor(advisor);
		proxyFactory.setTarget(simpleBean);
